• exim configuration: 503 AUTH command used when not advertised

  - by jrdioko

  I'm running a piece of software on a Windows server that sends email notifications via a remote SMTP server. It has very few configuration options, and only supports basic SMTP authentication without SSL/TLS. I have exim4 running on a Debian server that will be the SMTP server for this Windows program. It is set up with default configuration, plus allowing AUTH PLAIN and AUTH LOGIN unencrypted connections. I have successfully sent an email over telnet: telnet servername 25 ehlo test 250-AUTH PLAIN LOGIN ... auth plain XXX 235 Authentication succeeded mail from: ... ... However, the program I want to connect to this server fails to connect. To see why, I ran a packet sniffer during the connection, and see the following session: C: HELO hostname S: 250 Hello hostname C: AUTH LOGIN XXX | XXX S: 503 AUTH command used when not advertised | 500 unrecognized command C: QUIT S: 221 closing connection I'm not familiar enough with the SMTP protocol to understand what's going on here. What do I need to change on my exim4 SMTP server to allow for this connection to be made?

• Sign multiple domains with single Domain Key (dk-filter)

  - by Lashae

  Motivation The private shopping website GILT, send periodical update emails from giltgroupe.bounce.ed10.net however all of the mails are signed with domain keys of giltgroupe.com. mailed-by giltgroupe.bounce.ed10.net signed-by giltgroupe.com My Story I couldn't manage to sign x.com with y.com 's domain key using dk-filter under Debian Lenny with postfix. If I try to init dk-filter service with following arguments: DAEMON_OPTS="$DAEMON_OPTS -d x.com,y.com -c nofws -k -i /var/dk-filter/internal_hosts -s /etc/dk-keys.conf" dk-filter service signs with domain x.com (d=x.com) If I change the daemon arg.s as following: DAEMON_OPTS="$DAEMON_OPTS -d x.com -c nofws -k -i /var/dk-filter/internal_hosts -s /etc/dk-keys.conf" then emails sent From y.com is not being signed. the dk-keys.conf file is as follows: *:/var/dk-filter/y.com/mail I managed to do same thing with DKIM, works perfect. However DK doesn't seem to work. I don't have any problem signing y.com's emails with y.com's key and x.com's emails x.com's key, which indicates there is no configuration problem. Do you have any experience/advice to make it possible to sign emails from multiple domains by a specific chosen domain?

• Problems sending email using .Net's SmtpClient

  - by Jason Haley

  I've been looking through questions on Stackoverflow and Serverfault but haven't found the same problem mentioned - though that may be because I just don't know enough about how email works to understand that some of the questions are really the same as mine ... here's my situation: I have a web application that uses .Net's SmtpClient to send email. The configuration of the SmtpClient uses a smtp server, username and password. The SmtpClient code executes on a server that has an ip address not in the domain the smtp server is in. In most cases the emails go without a problem - but not AOL (and maybe others - but that is one we know for sure right now). When I look at the headers in the message that was kicked back from AOL it has one less line than the successful messages hotmail gets: AOL Bad Message: Received: from WEBSVRNAME ([##.###.###.###]) by domainofsmtp.com with MailEnable ESMTP; Mon, 18 Jun 2012 09:48:24 -0500 MIME-Version: 1.0 From: "[email protected]" <[email protected]> ... Good Hotmail Message: Received: from mail.domainofsmtp.com ([###.###.###.###]) by subdomainsof.hotmail.com with Microsoft SMTPSVC(6.0.3790.4900); Thu, 21 Jun 2012 09:29:13 -0700 Received: from WEBSVRNAME ([##.###.###.###]) by domainofsmtp.com with MailEnable ESMTP; Thu, 21 Jun 2012 11:29:03 -0500 MIME-Version: 1.0 From: "[email protected]" <[email protected]> ... Notice the hotmail message headers has an additional line. I'm confused as to why the Web server's name and ip address are even in the headers since I thought I was using the SmtpClient to go through the smtp server (hence the need for the username and password of a valid email box). I've read about SPFs, DKIM and SenderID's but at this point I'm not sure if I would need to do something with the web server (and its ip/domain) or the domain the smtp is coming from. Has anyone had to do anything similiar before? Am I using the smtp server as a relay? Any help on how to describe what I'm doing would also help.

• How to repair a damage transaction log file for Exchange 2003

  - by Markus Larsson

  Hi! Yesterday we had a power failure and the UPS did not work (it has worked perfect before). Everything seem to be ok when I started all the servers again except of the mail, when I try to mount the store I get the following message: “The database files in this store are corrupted” Server: Exchange 2003 running on a Small Business Server Latest full backup: one week old Backup program: Backup Exec 9.0 This is what I have done: 1. Copy every file in the MDBDATA folder (edb, stm, log) 2. Run Eseutil /d for priv1.edb 3. Run Eseutil /p for priv1.edb (took seven hours) 4. Run Isintig –fix –test alltests, now it breaks down. Isintig fails with the following error: Isinteg cannot initiate verification process. Please review the log file for more information. The problem is that there is no log file created. 5. Giving up on this route I decide to do a restore from the backup, it fails with the following error: Unable to read the header of logfile E00.log. Error -501, and the error: Information Store (5976) Callback function call ErrESECBRestoreComplete ended with error 0xC80001F5 The log file is damaged. My conclusion is that E00.log is damage, so how can I repair it so that I can restore the database? Or should I give up and try some other route?

• Emails going to Junk for Hotmail recipients

  - by David George

  We send daily mass emails to our customers (~30,000+ emails per day). We have problems with Hotmail users receiving our emails. Sometimes the email goes to the Junk folder, but often it will got to their inbox, but the content is blocked so the user sees a message saying "This email was blocked and may be dangerous". If an email is sent to GMAIL it is usually not blocked, but it does show up as from "Uknown" instead of the company. Please be advised I've done the following: 1. No RBLs Checked on - http://multirbl.valli.org/ 2. We do have SPF records published 3. We do have reverse DNS setup 4. Our company even signed up for the Junk Mail Reports Program at Hotmail Here is a sample header, I've noticed the X-SID-Result and the X-AUTH-Result both FAIL every time at Hotmail: X-Message-Delivery: Vj0xLjE7dXM9MDtsPTA7YT0wO0Q9MTtTQ0w9MQ== X-Message-Status: n:0 X-SID-Result: Fail X-AUTH-Result: FAIL X-Message-Info: JGTYoYF78jFqAaC29fBlDlD/ZI36+S6WoFmkQN10UxWFe1xLHhP+rDthGRZM87uHYM926hUBS+s0q46Yx9y6jdurhN6fx0bK Received: from privatecompany.com ([WanIPAddress]) by col0-mc3-f30.Col0.hotmail.com with Microsoft SMTPSVC(6.0.3790.4675); Wed, 5 May 2010 08:41:27 -0700 X-AuditID: ac10fe93-000013bc00000534-46-4be191a1618e Received: from INTERNAL-Email-SERVER([InternalIPAddress]) by privatecompany.com with Microsoft SMTPSVC(6.0.3790.4675); Wed, 5 May 2010 11:41:21 -0400 From: Private Company, Inc.<[email protected]> To: [email protected] Message-Id: <[email protected]> Subject: Date: Wed, 5 May 2010 11:42:46 -0400 MIME-Version: 1.0 Reply-To: [email protected] Content-Type: text/plain; charset="ISO-8859-1" Content-Transfer-Encoding: 8bit X-Brightmail-Tracker: AAAAAA== Return-Path: [email protected] X-OriginalArrivalTime: 05 May 2010 15:41:27.0837 (UTC) FILETIME=[6D06E4D0:01CAEC69]

• Recommendation for Document Management Solution

  - by BillN

  We've just been informed by our software vendor that the custom document management system they'd written is no longer in development, and will not be supported in the future. So we are looking at new document management systems. Requirements: Multiple input vectors, we receive documents via e-mail, fax, scanning, and from the originating application Ability to Redact or obscure data. Customers may fax an order with CC data, we want to attach the image of the order form with the order record, but the CC data needs to be protected. Same with Tax IDs. Certain users should be able to see the redacted data, but access should be logged. Version control on documents. We'd like Product Development and Marketing to be able to track various versions of documents like Packaging Designs, but ensure that users have the latest approved version. AD integration, my users don't need another password. Ability to integrate to other apps. Our current system, offers function keys in the order-entry system, that will spawn the viewer application, and open the correct document. Mass import facility, we have a half a terabyte of existing documents in the old system that we would like to import. Retention Policy. I'd like a way to have the system comply with the corporate retention policy, so that when a document of a certain type reaches a certain age, it gets deleted, or atleast marked for manual deletion. We are a Windows Server and HP-UX shop. Does anybody have any experience with Document Management systems that they would like to share? Thanks.

• SeLinux blocking connection to sshd on Ubuntu 9.10

  - by Barton Chittenden

  When I try to log on to my laptop, which runs Ubuntu 9.10, the server rejects my login attempts. Checking /var/log/auth.log, I see the following: Feb 14 12:41:16 tiger-laptop sshd[6798]: error: ssh_selinux_getctxbyname: Failed to get default SELinux security context for tiger I googled for this, and ran across the following: http://www.spinics.net/lists/fedora-.../msg13049.html Here's the part that I think relates to the problem that I'm having: Quote: What's wrong on my system? Why it's not possible to login even if selinux is in permissive mode? Any suggestions? I'd start by trying to figure out why sshd isn't running in sshd_t (it seems to be running in sysadm_t). Paul. selinux mailing list selinux@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mail...stinfo/selinux Yes, sshd is running in sysadm_t: ps axZ | grep sshd system_u:system_r:sysadm_t 3632 ? Ss 0:00 /usr/sbin/sshd -o PidFile=/var/run/sshd.init.pi ls -Z /usr/sbin/sshd system_ubject_r:sshd_exec_t /usr/sbin/sshd Don't know why it's not sshd_t. I didn't modified something. It's a standard installation of sles11 with the default reference policy from tresys. Maybe this code snippet from policy/modules/services/ssh.te is responsible for that: Allow ssh logins as sysadm_r:sysadm_t gen_tunable(ssh_sysadm_login, true) Any ideas? Do you have boolean init_upstart set to on? if not try setting it to on. I do not believe ssh_sysadm_login boolean works currently but i may be mistaken. -- Yeah, setting init_upstart to on did the trick! THANK A LOT! Do you know why this prevents the user from logging in through ssh even if selinux is set to permissive?? Ok, so the million dollar question is "where do I set 'init_upstart=1'"? It's not clear from context which configuration file needs to be edited, and I'm not at all familiar with SELinux configuration.

• Mac OS X: which folders should ClamXav Sentry watch?

  - by trolle3000

  I'm using ClamXav on my Mac. I've read this, and I am aware of the whole Macs-need-no-AV-but-they-do-anyway discussion. I guess that's why I would feel like a real jerk if I somehow managed to compromise my system! So ClamXav has been downloaded and ClamXav Sentry set up to start on log-in, but it doesn't really do anything before you tell it to. Specifically, you have to tell it which folders to watch for virusses/vira so I'm wondering, where are good places to look? Currently it's been set up to look the following places: In the home folder: ~/Downloads ~/Library/Caches ~/Library/Contextual Menu Items ~/Library/Cookies ~/Library/Internet Plug-Ins ~/Library/LaunchAgents In my system folder: /Library/Application Support /Library/Caches /Library/Contextual Menu Items /Library/Cookies /Library/Internet Plug-Ins /Library/LaunchAgents /Library/LaunchDaemons /Library/Startupitems Basically, this is 100% conjecture. All (most of) the folders have something to do with the Internet and things that start up automatically, so I'm guessing that's where vira go. But still, the qustion: Which folders should ClamXav Sentry watch, if any? FYI, I'm not using any mail applications, but please include that in your answer for anyone who might be interested.

• Postfix not sending email after upgrading to Ubuntu 12.04

  - by Luke

  After upgrading a server from Ubuntu 10.04 to 12.04, postfix is no longer sending email through sendgrid.com. I followed this guide about 6 months ago and everything had been working perfectly until the upgrade. Now it doesn't seem to be authenticating with sendgrid.

• Why are snapshots considered as temporary backups not real backups?

  - by Samselvaprabu

  I am using VMware ESXi. In our team we use to provide snapshots for long term backup. Then we faced issues like memory spillover and the server got hang up. I started reading in VMware knowledgebase articles and everywhere. Everywhere it was recommended not to have snapshots for a long time. Even VMware advised to keep snapshots for maximum of three days. But our team kept asking us to have at least two permanent snapshots (till deleting the VM). Sometimes we may use the VM for a year). one snapshot is for fresh machine state. (So when we complete testing an application, we will revert back to fresh state and install another application) (If I did not allow that, I may often need to host the VM.) Next snapshot for keeping the VM in some state (maybe they would have found an issue and keep that state for some time. Or they may install prerequisites for the application and keep the machine ready for testing.) Logically, their needs seems to be fair. But if I allow that, I am to permit them to hold the snapshots for long time. We are not using our VM as a mail server or database server. Why is keeping snapshots for long time having an adverse effect? Why are snapshots considered as temporary backups, not real backups?

• Easiest way to send encrypted email?

  - by johnnyb10

  To comply with Massachusetts's new personal information protection law, my company needs to (among other things) ensure that anytime personal information is sent via email, it's encrypted. What is the easiest way to do this? Basically, I'm looking for something that will require the least amount of effort on the part of the recipient. If at all possible, I really want to avoid them having to download a program or go through any steps to generate a key pair, etc. So command-line GPG-type stuff is not an option. We use Exchange Server and Outlook 2007 as our email system. Is there a program that we can use to easily encrypt an email and then fax or call the recipient with a key? (Or maybe our email can include a link to our website containing our public key, that the recipient can download to decrypt the mail?) We won't have to send many of these encrypted emails, but the people who will be sending them will not be particularly technical, so I want it to be as easy as possible. Any recs for good programs would be great. Thanks.

• ULogd2.x - Documents - IPFIX data generation

  - by Gomathivinayagam

  I would like to generate IPFIX data from the packets that are coming to my local system as part of experimentation. It seems ULogd is a good tool to do that. I am able to capture PCAP data. But there are very less documents available on ULogd2.x about IPFIX format data generation.(There are very few examples provided in ulogd.conf). Can you provide me any links that describes about how to generate IPFIX data using ulogd2.x? 1) What are the options available? I saw there is polling interval configuration. But I have no idea how does it work? 2) If I set hash_enable = 0, and uncomment the polling_interval value, I'm getting an exception as NFCT plugin requires hash table, evne though I have specified hash_buckets and hash_max_entries. Could you help on this? 3) In general, I would like to know how NFCT plugin works in ulogd2.x. I sent mail to ulogd mailing list, but there are no replies. Could you shed some light?

• Exchange Out of Office Reply reset

  - by Richard West

  I have a question. We have an employee that is going to be on maternity leave for the next 8 weeks. I think that Outlook/Exchange is designed to send one out of office message to each person that sends an email to my user for the duration of the out of office reply. Meaning that if someone sends an email to my user each week they are only going to receive one out of office message - the first time they send her an e-mail. My concern is that over time people might forget that she is out of the office. Since they are not receiving any type of reply when they send an email this would seem possible. Does anyone know if Exchange ever resets the out of message notification after a certain amount of time? Like a week or so? I'm not looking for every message to get an out of office message, but I think more than one over the course of 8 weeks would be appropriate. I know that I can turn off and turn back on the out of office assistant to "reset" the replies, but I'm curious if Exchange performs a reset after a certain period of time automatically.

• Keyboard's media keys are blocked by a program

  - by Mike Hanson

  I've got a Microsoft Natural Ergonomic Keyboard 4000. In addition to the regular keys, it's also got keys for Web/Home, Search, Mail, Favorites (5), Calculator, and Media functions (Mute, Volume Up/Down, and Play/Pause). Everything works most of the time, and the exception is rather odd. I use a programming system called Clarion. When that has focus, the Media keys don't work. (All the others still do.) I've also discovered that programs that I create using Clarion also block the media keys (only when they have focus). This indicates that it's probably something in Clarion's Run-Time Library (RTL) that's causing the trouble. The keys will work if I click on a non-Clarion window before hitting the media key, but that's an undesirable hassle. The odd thing is that I have many colleagues with the same keyboard, and they have no problem. When I recently upgraded from Vista Professional to Win7 Ultimate, I noticed that various things "appear" differently. For example, with my old system, when I changed the volume or muted the volume bar visualization always appeared at the bottom right on the screen. Now it doesn't appear in certain programs, even when it works. This indicates an order of precedence for visual elements. I'm fairly certain a similar order of precedence exists for keyboard hooks. Depending on how the hooks are defined, and the order in which they're applied, it would seem that sometimes the IntelliType drivers don't see the media keystrokes. The Media keys probably behave differently than the rest of the "special" keys, because they are more of a standard across all keyboards, so perhaps are handled by a different driver hooking mechanism. Does anyone have any suggestions of how I might fix this problem? Is there some way to change the order of hooks? Delay the loading of the IntelliType driver? Thanks in advance!

• Working with barcode fonts in Word

  - by Bob Rivers

  I need to create labels in Microsoft Word 2010 with numbers encoded as barcodes. The barcode's format (ean, code39, upc, etc) does not matter. I have downloaded a barcode conversion font that I found at this site. When I type the number that I want and then I format it with my new font, it produces a barcode. I then print it on an OKI laser printer (1200 dpi). The result seems to be fine, at least for common people. But, when I try to scan it, nothing happens. I tried both with a barcode scanner and a data collector, but neither of them read the barcode. My barcode scanner is working fine, because I can read commercial barcodes printed on products. Does anybody have any advice? How do I do this kind of stuff? I want to do it using Word because I will generate labels using Mail Merge. Therefore using external programs aren't option for me.

• Live Mesh starts exactly once on fresh Win7 Ultimate installation

  - by Reb.Cabin

  I did a fresh install of Windows 7 Ulimate 64-bit on a formatted drive on a refurbed Lenovo PC, applied all 102 (!) windows updates, windows seems to be working fine. No quirks installing, no apps, no junkware, just straight, legal, Win7 Ultimate right from an unopened 2009 Microsoft box. Ok, breathe sigh -- Install Live Mesh (no messenger, no mail, no writer, no photo, none of the rest of the Windows Live freeware). Set up my shares, let it run overnight. watch MOE.exe in the Task-Manager perf pane to make sure it's all settled down. reboot. Ok, check that MOE is running and files are getting updated properly from other machines in the mesh. Great. HOWEVER -- when I try to launch Windows Live Mesh app from the Start jewel, I get a brief hourglass, then nothing. Reboot. Same story. result -- the shares I already posted seem to be synching properly, but I can't run the app, so I can't add and delete shares. The background process MOE seems to run, but I can't get the app going. btw, the reason I did this fresh install is I had exactly the same experience running Vista, so I wiped the machine hoping it would solve this nasty problem. Imagine my surprise! Will be grateful for clues, advice, etc, please & thanks!

• How to compress .pdfs in word 2007?

  - by chobo2

  Hi I am trying to send my cover letter and resume away but apparently it is too big to send through craigs list(my computer says the total size is 500kb) as it has a 600kb limit(so small should be at least a meg). Hi there. You recently tried to email Some job Email, an anonymous craigslist address. However, your message was too big to be sent through our system. Craigslist has a 600KB limit on the messages we'll send. Please reduce the size of your mail and try again. Thanks for using craigslist. So when I convert my word 2007(.docx) files to pdf they become huge. Like they got from 32kb to 320kb. So is there a way I can either get around craigslist limits or compress my pdfs a bit to make it happy. I don't want to send zips and stuff since the person who gets it might not even know what to do. I rather not send .docx since not sure if will have office 2007 or the compatibility view installed and I rather just send it as pdf(as some place require it anyways to be in pdfs). Thanks

• A possible case of hacked email account. What kind of an attack is this?

  - by Rickesh John

  I own a Yahoo mail account. I am using this account for sending resumes and receive notifications from various job portals. But yesterday, I found that some 10-15 mails had been sent to random addresses from my account. Most of them had this format: hr@<companyname>.com I am pretty sure that I didn't send any mails to such addresses. Initially, I thought the job portals may be sending mails on my behalf and Yahoo is logging them, but then I saw the contents. The contents of all those mails were a URL, which I did not click. SCARED. Also, to top it off, my "Sending Name" has been changed to 'Nice Maria'!! o_0 I have taken the necessary measures and changed my password and the secret question. I cannot delete this account as this email is registered with all the job portals and other companies. Is this a simple case of my account being compromised or was I a victim of some web vulnerability? All the mails seem to be bot generated, with only a URL as the message body. Please advice.

• Only one domains not resolving via Windows DNS server at multiple locations, but is at others

  - by Brett G

  I'm having quite a weird issue. Had mail delivery issues to a specific domain. After looking closer, I realized that the DNS for that domain isn't resolving via the in-house Windows 2003 SP2 DNS server. C:\>nslookup foodmix.net Server: DC.DOMAIN.com Address: 10.1.1.1 DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. *** Request to DC.DOMAIN.com timed-out (DC.DOMAIN.com and 10.1.1.1 are generic values to replace the actual ones) Even if I run this nslookup from the DC.DOMAIN.com server, I get the same result. However, all other requests are working as they should. I tried it on severs at completely separate organizations on different networks(Windows 2003 AD servers). The weird thing is some of these were having the same exact issue. However using public DNS servers work. I have tried clearing the DNS cache, restarting the server, restarting the services, etc. Nothing has worked. One weird event I noticed in the DNS Server Event Logs that might be related is an event ID of 5504 with the following description: The DNS server encountered an invalid domain name in a packet from 192.33.4.12. The packet will be rejected. The event data contains the DNS packet. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. In the data section below, I can see the following mentioned: ns2.webhostingstar.com Which happens to be the nameserver for the domain in question. Several discussion threads and a MS KB have pointed to disabling EDNS. I have done this via "dnscmd /config /enableednsprobes 0" and it has not fixed the issue.

• Need to get SMTP server on MS Server 2003

  - by Matt Dawdy

  Long story short, client paid networking company to move their website in house. Now I have to figure out how to email out from their website even though they don't have an SMTP server. At least until I install one. Their email is hosted with Gmail right now (the client's domain through Google App for Your Domain). I changed my code to connect as one of their users "[email protected]" and send email. Worked great for about 12 hours. All of a sudden none of the automated emails are going out now, and google is sending the emails back saying that it is a permanent failure and Message Rejected. The link they direct me to, http://mail.google.com/support/bin/answer.py?answer=69585 is telling me that our emails look like spam. They aren't. They are emails we send to out clients about the status of their applications. Seriously, they are NOT spam. So...long story short is out the window, sorry...but I need to get an SMTP server setup inside their domain that I can send emails out of. This thing won't need to receive emails ever, and really only needs 1 email account customercare. What can I do? Will I have to have the networking company open a port in the firewall? Is there one built into Server 2003?

• LDAP Authentication woes

  - by Marcelo de Moraes Serpa

  Hello list, I have a local OpenLDAP server with a couple of users. I'm using it for development purposes, here's the ldif: #Top level - the organization dn: dc=site, dc=com dc: site description: My Organization objectClass: dcObject objectClass: organization o: Organization #Top level - manager dn: cn=Manager, dc=site, dc=com objectClass: organizationalRole cn: Manager #Second level - organizational units dn: ou=people, dc=site, dc=com ou: people description: All people in the organization objectClass: organizationalunit dn: ou=groups, dc=site, dc=com ou: groups description: All groups in the organization objectClass: organizationalunit #Third level - people dn: uid=celoserpa, ou=people, dc=site, dc=com objectclass: pilotPerson objectclass: uidObject uid: celoserpa cn: Marcelo de Moraes Serpa sn: de Moraes Serpa userPassword: secret_12345 mail: [email protected] So far, so good. I can bind with "cn=Manager,dc=site,dc=com" and the 12345678 password (the local server password, setup on slapd.conf). However, I would like to bind with any user in under the people OU. In this case, I'd like to bind with: dn: uid=celoserpa, ou=people, dc=site, dc=com userPassword: secret_12345 But I'm getting a "(49) - Invalid Credentials" error everytime. I have tried through CLI tools (such as ldapadd, ldapwhoami, etc) and also ruby/ldap. The bind with these credentials fails with a invalid credentials error. I thought that it could be an ACL issue, however, the ACLs on slapd.conf seem to be right: access to attrs=userPassword by self write by dn.sub="ou=people,dc=site,dc=com" read by anonymous auth access to * by * read I was suspecting that maybe OpenLDAP doesn't compare against userPassword? Or maybe some ACL configuration I am missing that is somehow affecting the read access to userPassword for the specific DN. I'm really lost here, any suggestion appreciated! Cheers, Marcelo.

• Emails sent to outlook.com not being delivered

  - by imukcedup

  I'm having an issue that is a little strange. I have a cPanel webserver that I own and have root. I was testing out emailing and noticed some issues. When I send an email to outlook.com address the email sends ok but nothing is recieved at the outlook mailbox. I also dont get an 'email delivery failure notification' in any mailbox. 2014-06-12 09:53:47 SMTP connection from [127.0.0.1]:45334 (TCP/IP connection count = 1) 2014-06-12 09:53:47 1Wv5Rr-0003rA-2K <= [email protected] H=localhost (ourdomain.com) [127.0.0.1]:45334 P=esmtpa A=dovecot_login:joe S=667 [email protected] T="This is a test message" for [email protected] 2014-06-12 09:53:47 SMTP connection from localhost (ourdomain.com) [127.0.0.1]:45334 closed by QUIT 2014-06-12 09:53:50 cwd=/var/spool/MailScanner/incoming/1029481 5 args: /usr/sbin/exim -C /etc/exim_outgoing.conf -Mc 1Wv5Rr-0003rA-2K 2014-06-12 09:53:50 1Wv5Rr-0003rA-2K SMTP connection outbound 1402581230 1Wv5Rr-0003rA-2K ourdomain.com [email protected] 2014-06-12 09:53:50 1Wv5Rr-0003rA-2K => Test Account <[email protected]> R=archive_outgoing_email T=archiver_outgoing 2014-06-12 09:53:52 1Wv5Rr-0003rA-2K => [email protected] R=dkim_lookuphost T=dkim_remote_smtp H=mx1.hotmail.com [65.54.188.110] X=UNKNOWN:AES128-SHA256:128 C="250 <[email protected]> Queued mail for delivery" 2014-06-12 09:53:52 1Wv5Rr-0003rA-2K Completed I have checked the outlook.com's spam folders and its not in there either. This is a new IP address allocation from our ISP and there was a block on gmail addresses, so we know it was used for spam. But with gmail we got a notifaction of failure and I know outlook/microsoft also send out notification. Does anyone know what could be happening here? Thanks

• Advance DNS - Redirecting Emails to new webhost

  - by Martin

  I am not to sure if this question belongs here but I will surely find out soon enough. I have two web hosts (Not sure why it has been setup this way but it has). I do not want to use the original web host to handle the emails as the Data that we get from them is 500 mb which is already full with hosting the website. The second web host has an unlimited data plan and was created so we could use this host for the email accounts. Now the problem is I have reset the Advance DNS Zone records on both accounts and I am not sure what they were before. (Silly me should have taken a backup of how it was setup before hand I know) Emails were working before and going to the second hosts server now they are going to the first host but it has no email addresses setup for use so all emails are bouncing saying that the address does not exist. Host 1 IP: 192.185.96.110 Host 2 IP: 27.54.88.66 So far I have changed the Advanced DNS Zone record on Host 1 with the following: A Record: mail.australisinstitute.qld.edu.au - 27.54.88.66 I have not made any changes on Host 2 and both hosts have the default MX Records. If I need to provide any more information I can but I just hope someone can decipher what I have said haha. Cheers in advance!

• Postfix Whitelist before recipient restrictions

  - by GruffTech

  Alright. Some background. We have an anti-spam cluster trucking about 2-3 million emails per day, blocking somewhere in the range of 99% of spam email from our end users. The underlying SMTP server is Postfix 2.2.10. The "Frontline defense" before mail gets carted off to SpamAssassin/ClamAV/ ect ect, is attached below. ...basic config.... smtpd_recipient_restrictions = reject_unauth_destination, reject_rbl_client b.barracudacentral.org, reject_rbl_client cbl.abuseat.org, reject_rbl_client bl.mailspike.net, check_policy_service unix:postgrey/socket ...more basic config.... As you can see, standard RBL services from various companies, as well as a Postgrey service. The problem is, I have one client (out of thousands) who is very upset that we blocked an important email of theirs. It was sent through a russian freemailer who was currently blocked in two of our three RBL servers. I explained the situation to them, however they are insisting we do not block any of their emails. So i need a method of whitelisting ANY email that comes to domain.com, however i need it to take place before any of the recipient restrictions, they want no RBL or postgrey blocking at all. I've done a bit of research myself, http://www.howtoforge.com/how-to-whitelist-hosts-ip-addresses-in-postfix seemed to be a good guide at first, almost fixing my problem, But i want it to accept based on TO address, not originating server.
