  • Zend Mail - bouncing mails not returning to the specified "Return-Path"

    - by Leprosy
    Hi, i'm working on a simple mail list app in PHP using Zend Mail. The idea is that all mail that bounce is redirected to a script which processes them and a report is generated. The script is running ok in direct tests, but I've testing it with fake mail address to test the mail list app, and it appears that the mail is not being redirected to the correct email address. Zend Mail provides the setReturnPath method to set the "Return-Path" header, it's ok to use this header for this purpose? Thanks

  • How to configure sendmail to relay local user mail to public host?

    - by Chau Chee Yang
    I am using Linux/Fedora's sendmail as my mail server. The server do not has a public domain name. It connect to Internet via dial-up. There are few users in the server. I have successfully configure my sendmail to relay mail to public host (via smart_host): # mail <user>@gmail.com [email protected] receive mail from this private host. However, if I send a mail to local user (without domain name): # mail <user> All mails are deliver to my server's mail spooler (/var/spool/mail). I wish all mails send to local user may relay to a public domain that I have registered, is that possible to do so with sendmail? mail user1 will send mail to [email protected] mail user2 will send mail to [email protected]

  • Network: Incoming connections work, outgoing fails

    - by anirvan
    i recently set up my own server at home to run Ubuntu 12.04 server ed. on booting up, i noticed that a message related to networking comes up, and the booting process pauses. the message read something like - waiting for network configuration and after a while - waiting another 60 seconds... on booting up, I realised that any command which requires a network connection was not working - ping, apt-get install, etc. on firing the ifup eth0 command, I get the error RTNETLINK answers: File exists. Failed to bring up eth0. I also realised, while searching the web for this problem, that this is probably one of the most common networking related issues - however, most of the questions are around setting up multiple IPs for the same machine. ifdown eth0 also fails, stating that eth0 is not configured. my /etc/network/interfaces file has a simple configuration for a static IP: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address xx.xx.xx.xx netmask xx.xx.xx.xx broadcast xx.xx.xx.xx gateway xx.xx.xx.xx dns-nameservers xx.xx.xx.xx The strangest part of this problem is that, while I can't connect to anything outside, I can ping to this particular server using the static IP configured in the interface file, and, i can even SSH into it! I'm really at ends here with this problem, and any guidance is much appreciated. Thanks!

  • Linux: prevent outgoing TCP flood

    - by Willem
    I run several hundred webservers behind loadbalancers, hosting many different sites with a plethora of applications (of which I have no control). About once every month, one of the sites gets hacked and a flood script is uploaded to attack some bank or political institution. In the past, these were always UDP floods which were effectively resolved by blocking outgoing UDP traffic on the individual webserver. Yesterday they started flooding a large US bank from our servers using many TCP connections to port 80. As these type of connections are perfectly valid for our applications, just blocking them is not an acceptable solution. I am considering the following alternatives. Which one would you recommend? Have you implemented these, and how? Limit on the webserver (iptables) outgoing TCP packets with source port != 80 Same but with queueing (tc) Rate limit outgoing traffic per user per server. Quite an administrative burden, as there are potentially 1000's of different users per application server. Maybe this: how can I limit per user bandwidth? Anything else? Naturally, I'm also looking into ways to minimize the chance of hackers getting into one of our hosted sites, but as that mechanism will never be 100% waterproof, I want to severely limit the impact of an intrusion. Cheers!

  • What does "incoming" and "outgoing" traffic mean?

    - by mgibsonbr
    I've seen many resources explaining how to set up a server's firewall to allow incoming and outgoing traffic on HTTP standard ports (80 and 443), but I can't figure out why I would need either of them. Do I need to unblock both for a "regular" web site to work? For file uploads to work? Are there situations where it would be advisable to unblock one and leave the other blocked? Sorry if that's a basic question, but I couldn't find it explained anywhere (also I'm not a native english speaker). I know in a "regular" web site the client is always the one who initiates a request, so I'm assuming a web server must accept incoming traffic on those ports, and my common sense tells me the server is allowed to send a response without unblocking anything else (otherwise it wouldn't make sense to have two types of rules). Is that correct? But what is an outgoing web (service) traffic, and what would be its use? AFAIK if the server wanted to initiate a connection with another machine, the specific port that matters is the one in the other end (i.e. the destination port would be 80), on its end any free port could be used (the source port would be random). I can open HTTP requests from my server (using wget for instance) without unblocking anything. So I'm assuming my concepts of "incoming" and "outgoing" are wrong somehow.

  • Tracking Outgoing Links With Google Analytics Events

    - by the_archer
    I've been trying to track clicks on external links on my website using the events tracking method. So I've got my Google Analytics code setup before body ends as shown below (note: quotes have been entitied by blogger, but it works fine): <script type='text/javascript'> var _gaq = _gaq || []; _gaq.push([&#39;_setAccount&#39;, &#39;UA-XXXXXXX-X#39;]); _gaq.push([&#39;_trackPageview&#39;]); (function() { var ga = document.createElement(&#39;script&#39;); ga.type = &#39;text/javascript&#39;; ga.async = true; ga.src = (&#39;https:&#39; == document.location.protocol ? &#39;https://ssl&#39; : &#39;http://www&#39;) + &#39;.google-analytics.com/ga.js&#39;; var s = document.getElementsByTagName(&#39;script&#39;)[0]; s.parentNode.insertBefore(ga, s); })(); </script> Now I wanted to track a link on the addthis.com follow widget. So there is a link of the type below to which following instructions from here I added the onclick event. <a addthis:url='http://feeds.feedburner.com/myfeedburnerlurl' onClick="_gaq.push(['_trackEvent', 'Subscription Clicks', 'RSS']);" class='addthis_button_rss_follow'/> I clicked on it a couple of times, left it for over a day now, but nothing shows up in google analytics events. It just says zero events. Here's a screenshot of the events page on GA: Could anybody help me? Am I doing anything wrong?

  • Regulating outgoing traffic on ubuntu VM

    - by DazSlayer
    I am making a virtual network setup for my high school cybersecurity team to practice. I am connecting all the VMs together through a VPN and then people who are practicing will VPN in and ssh/remote desktop into the different VMs. The problem is that for practicing, they will need root access into the VMs and because the VMs are connecting to my personal network, the VMs pose a security risk to my personal network. Is there any way in either VMWare or VirtualBox or even making an unchangeable iptable (I can make all the windows VMs go thru a linux VM) to prevent people from connecting to my local network via the VM?

  • Can I mark an Email as "High Importance" for Outlook using System.Net.Mail?

    - by ccornet
    Part of the application I'm working on for my client involves sending emails for events. Sometimes these are highly important. My client, and most of my client's clients, use Outlook, which has the ability to mark a mail message as High Importance. Now, I know it is callous to assume that all end users will be using the same interface, sp I am not. But considering you can send email from Outlook as High Importance even if the target is not necessarily reading through Outlook, that means that there is basically some data stored... somehow... that lets Outlook know if a particular message was assigned as High Importance. That's my interpretation, at least. The application currently uses System.Net.Mail to send out emails, using System.Net.Mail.MailMessages for writing them and System.Net.Mail.SmtpClient to send them. Is it possible to set this "High Importance" setting with System.Net.Mail's abilities? If not, is there any assembly available which can configure this setting?

  • Unable to connect to mail server via IMAP and roundcube

    - by mrhatter
    I am having trouble getting the final parts of my mail server up and working. I followed this tutorial to get everything set up on the mail server side. I have installed roundcube for webmail and configured it but it is saying "error connecting, connection refused" when attempting to connect to it using IMAP. This is thorough the "test imap" section of its installer. Also it is giving me an error message about perissions for it's log and temp folders but that's not as important as acutally getting mail to work. I have also tried connecting to the mail server using thunderbird however it cannot establish a connection either and I know my login information is correct. I know that the databases are working correctly based on the roundcube installer telling me that they have been "successfully initialized". Here are my firewall rules -A INPUT -i lo -j ACCEPT -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -p tcp -m tcp --dport 25 -j ACCEPT -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT -A INPUT -p tcp -m tcp --dport 443 -j ACCEPT -A INPUT -p tcp -m tcp --dport 465 -j ACCEPT -A INPUT -p tcp -m tcp --dport 487 -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 993 -j ACCEPT -A INPUT -j DROP Which I set up in iptables. I have modified them from what I used in this tutorial I'm not sure what to try next. Any help would be wonderful! I am using Ubuntu 14.04 server, apache 2.4.7, roundcube 1.0.1, and the latest versions of dovecot and postfix. The email databases are contained in mysql. I am running this on a VPS server. UPDATE: I have changed from iptables to using ufw. I have run the following commands to set up a basic firewall with ufw. ufw default deny ufw allow ssh ufw allow http ufw allow https ufw allow imap ufw allow imaps ufw allow smtp I then used telnet to check all of the mail ports. But Port 993 isnt working even though ufw says both 993 and 993/tcp are open. What am I missing?

  • My SMTP's outgoing mail gets bounced

    - by BloodPhilia
    I've got a ISPconfig 3 production server set up, running Ubuntu Server 9.04. My e-mail gets delivered ok to almost every other server I send mail to except for one (smtp.chello.nl which bounces my email). In my /var/log/mail.err I found the below error. Sep 23 08:59:33 <MYHOSTNAME> postfix/smtp[26944]: 3DB2B1456149: to=<<RECIPIENT>@chello.nl>, relay=smtp.chello.nl[213.46.255.2]:25, delay=2, delays=0.02/0.01/1.9/0.04, dsn=5.1.0, status=bounced (host smtp.chello.nl[213.46.255.2] said: 550 5.1.0 Dynamic/Generic hostnames are blocked. Please contact your Email Provider. Your IP was <MY IP>. Your hostname was ??. (in reply to MAIL FROM command)) What could be the cause of this? I did an SMTP check on mxtools.com and got the following: OK - Not an open relay OK - 0 seconds - Good on Connection time OK - 1.482 seconds - Good on Transaction time OK - 83.161.xx.xx resolves to a83-161-xx-xx.xxx.xxx.nl WARNING - Reverse DNS does not match SMTP Banner Update: My IP is static.

  • Stop Outgoing Spam Already Tagged as Spam

    - by me
    Hi, I run a Postfix server with Amavis and Spamassassin among other things. Postfix receives mail from the outside world and passes it on to Amavis. Amavis has Spamassassin rate the mail, and then tags it as spam if necessary. Then Postfix relies on each users' procmailrcs to deal with the mail as they will. I believe this is the correct approach because I believe each user should have the ability to choose what to do with their spam. Unfortunately, we also have some users with foregin domains in our virtual alises list. Because these addresses don't have user accounts with our servers, the spam that is forwarded to them is never put through a procmailrc and we end up forwarding spam, already tagged as spam, to other servers. Is there a way to stop outgoing mail already tagged as spam? Or is there any other way to fix this? EDIT: I only wish to delete the messages that are both spam AND being forwarded to other servers. I don't want to delete all mails marked as spam. Is there a way to distinguish between the two?

  • SPF for two different outgoing servers?

    - by Marcus
    I have ran into a problem that I think someone should have a really clever answer for. Today we have our own mailserver that looks like "mail.domain.com" – which we use to send out mail to our customers (with a modified PHPMailer script). Usually around 5000 mails every day. Everything from customer support to invoices goes through there. The from-header is set to "[email protected]". We are now thinking of migrating to Google Apps for internal use (with 70+ users). However, we cannot use Gmails SMTP for sending "bulk" mails (they have a limit of 500 outgoing mails per day) so we really want to keep using our current system for sending automated mail to our customers – and using gmails SMTP for our internal use. So, how do we set up our SPF-records (Sender Policy Framework) for this? We do not want to get stuck in any filters for "spoofing" the sender from either type of account (the ones sent from our own server, and through Gmails). In short: we want to be able to use the same e-mail adress (for sending) on two different SMTP servers (and therefore two different IP-adresses). Anyone with a good knowledge off SPF who knows how to go about? Or if it is even possible? Anything else I should think of when switching to Google Apps?

  • Postfix : outgoing mail in TLS for a specific domain

    - by vercetty92
    I am trying to configure postfix to send mail in TLS (starttls in fact), but only for a specific destination. I tried with "smtp_tls_policy_maps". This is the only line in my main.cf file regarding TLS configuration, but it seems not working. Here is my main.cf file: queue_directory = /opt/csw/var/spool/postfix command_directory = /opt/csw/sbin daemon_directory = /opt/csw/libexec/postfix html_directory = /opt/csw/share/doc/postfix/html manpage_directory = /opt/csw/share/man sample_directory = /opt/csw/share/doc/postfix/samples readme_directory = /opt/csw/share/doc/postfix/README_FILES mail_spool_directory = /var/spool/mail sendmail_path = /opt/csw/sbin/sendmail newaliases_path = /opt/csw/bin/newaliases mailq_path = /opt/csw/bin/mailq mail_owner = postfix setgid_group = postdrop mydomain = ullink.net myorigin = $myhostname mydestination = $myhostname, localhost.$mydomain, localhost masquerade_domains = vercetty92.net alias_maps = dbm:/etc/opt/csw/postfix/aliases alias_database = dbm:/etc/opt/csw/postfix/aliases transport_maps = dbm:/etc/opt/csw/postfix/transport smtp_tls_policy_maps = dbm:/etc/opt/csw/postfix/tls_policy inet_interfaces = all unknown_local_recipient_reject_code = 550 relayhost = smtpd_banner = $myhostname ESMTP $mail_name debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin xxgdb $daemon_directory/$process_name $process_id & sleep 5 And here is my "tls_policy" file: gmail.com encrypt protocols=SSLv3:TLSv1 ciphers=high I also tried gmail.com encrypt My wish is to use TLS only for the gmail domain. With this configuration, I don't see any TLS line in the source of the mail. But if I tell postfix to use TLS if possible for all destination with this line, it works: smtp_tls_security_level = may Beause I can see this line in the source of my mail: (version=TLSv1/SSLv3 cipher=OTHER); But I don't want to try to use TLS for the others domains...only for gmail... Do I miss something in my conf? (I also try whith "hash:/etc/opt/csw/postfix/tls_policy", and it's the same) Thanks a lot in advance

  • Setting Gmail as mail server

    - by Tim S.
    I’m in a slightly weird situation right now, and I don’t have sufficient knowledge to sort this myself without truly understand what I’m doing. Yesterday, I’ve registered a domain (.com) and ordered a VPS, attached to that domain. Chances are I may receive mail on my .com address to confirm the domain. Unfortunately, that domain is nothing, but an empty domain. Currently, there’s no mailserver that fetches my mail. Because I don’t have a mailserver available, I (temporarily) want to use Gmail. I prefer to add it to my existing, personal address, but I’m okay with creating a new account as well. I just want to read possible incoming mails. I’ve tried to set MX records to What do I need to do to get mail to a Gmail address? PS. I’m aware of Google, NSA, etc. PPS. I just want to receive mail. I don’t care if I can’t send via my domain. PPS. Detailed steps would be greatly appreciated, I’m a noob.

  • HOWTO Catch/Redirect all outgoing e-mails on Win2K and Redhat Enterprise

    - by John
    Background: I am integrating two separate web application that are developed in ASP .NET and JSP/Struts. As such, they are hosted on two different server technologies, namely Win2K3 and Redhat Enterprise Server 5.5. Problem: There is a copy of production data in my test environment with real e-mail addresses. I need to test the e-mail functionality of these applications, but I do not want them to send out actual e-mails. Is there a way to catch and redirect all outgoing e-mails? Ideally, I would like to send all outgoing e-mails to another e-mail (i.e., [email protected]) so my testers can look at them. Thanks for the help in advance!

  • Postfix configuration: different outgoing hosts based on sender

    - by Joe
    I've seen a few answers to this on the web, but nothing definitive nor any good examples. I relay all my mail out through Postfix, currently everything sent to my ISP's mail server. However, there are a few users with gmail accounts or gmail-hosted accounts; I'd like to route their outgoing mail through Google's servers (since it will then appear in their Gmail sent folder). All email NOT from one of these senders should go out through the default relayhost. I believe I need to use the "sender_dependent_default_transport_maps" configuration within Postfix, but can't find a good example on what this setup looks like. Can anyone point me at a specific setup?

  • Configure Postfix for outgoing mail

    - by Savvas Sopiadis
    I have the following scenario i must implement using Postfix (but don't know how to begin): Say we have a domain aaa.com which is hosted somewhere (this is already functioning without any problems). On this envirnoment there is already a Mail server though which we can send and receive mail (this mail server is limiting us to a very small number of emails/day). Now we have setup a VPS (virtual private server) on which we installed Postfix, which sole porpuse is to send emails on behalf of domain aaa.com. The Postfix server will be used by a program like Outlook to send the email. What configuration has to be done? (i 'm a bloody beginner in this field!) Thanks in advance
