• iRedMail home setup - use different SMTP relay for different destination domains

  - by John

  Hello helpful server folks, I'm messing with iRedMail. I've mostly been successful, I think I have an SMTP problem. I have changed RoundCube (webmail) to use BrightHouse's, my ISP's, SMTP server for outgoing. It works fine, I click send and poof, I have gmail. I can reply from gmail to my email server, and it works. It took 10 hours for the email to show up, which is a different problem, I think, but it does work. But when I send from my server TO my own server, my ISP's Postmaster account sends me a cryptic blurb. I just got off the phone with them, and they say it "should work", and that they can't reach my pop3 server. (pop3, pop3s, imap, and imaps are all open on my router and forwarded to the server, I'm not sure what I need, I'm just covering my bases...) pop3 and/or imap as external interfaces are just formalities, I really just want webmail to work. Roundcube only takes one SMTP server in its configs. How can I configure Postfix to relay / forward emails to my ISP's SMTP, while taking messages bound for my own domain and processing them? Since my ISP won't let me "bounce" my emails off of it. Maybe I'm vastly misunderstanding how e-mail works in general: To receive mail, I should only need port 25, SMTP, open to the internet, correct? Should I be concerned about some authentication failure from the outside to my relay? (My relay requires user/pass to use, my ISP's requires none.)

• Outlook 2007, how to stop replies from being sent if they meet criteria

  - by CChriss

  I have my college's email account auto-forwarded (they don't offer pop3 or imap) to my main gmail account so I don't have to go to their website to check for mail. That gmail account, and others, use pop3 down to my Outlook 2007. In my Outlook, I have a rule that puts mail sent to my @college address into a folder named Collegemail. Since the college email system lacks pop3 or imap, I have to go to their site to send a reply, so that the reply will be sent from my @college email address. The problem is that I cannot seem to get into the habit of going to my college's website to reply to those emails, so quite often I reply to them while in Outlook, which means my replies are sent "from" my main gmail address. How can I set up Outlook to either 1) disable replying to emails in the Collegemail folder or to emails where my college email address is in the original To: line, or else 2) set it to send those replies from a non-functional dummy account. The dummy account would be unable to send the email so the email would be stuck in the Outbox. (I already have the non-functional dummy account set up as Outlook's "Default" account. When I compose a new mail I have to deliberately pick one of my good accounts to send the new mail with, or else Outlook uses the default dummy account and the email stays in the Outbox with a Send error.) Thanks. Update: Anybody? Please help.

• How to fix GMail time stamps in Outlook?

  - by SWB

  One of my email accounts is hosted at an ISP with unreliable IMAP support, and I can't change it. Fortunately, I have my personal email set up on Google Apps for Domains, so I created another GMail account there and turned on GMail's features that allow me to send and receive mail through the ISP account using GMail ("Send mail as" and "Get mail from other accounts" in GMail settings on the Accounts tab). I'm now using Outlook to retreive mail from the GMail account through IMAP, which in turn is retreiving mail from the ISP account through POP3. This basically works great, except for one very significant issue: Prior to setting this up, I already had several months of mail in the ISP account that I had been accessing via IMAP. GMail grabbed all of this mail via POP3 at, let's say, noon on April 5. In GMail's web interface (and on my iPod touch, and in Mozilla Thunderbird), all is well: the messages are all shown with their original time stamps. But when Outlook downloads these messages from GMail via IMAP, the time stamps are all set to noon on April 5 (the time GMail downloaded them from the ISP via POP3). That's not good, especially since we're talking about hundreds of messages here over a time span of several months. How can I fix this and get Outlook to display the original time stamps?

• Recommendations for good Unix MTA / groupware solutions? [closed]

  - by Jez

  Possible Duplicate: Exchange server replacement that runs on Linux I'm setting up a Debian server, and one of the things I need on it is an MTA. I don't want to use something like Exim or Postfix because I want something that ties in SMTP, POP3, and IMAP all in one (a la Microsoft Exchange). Most MTAs also seem to be hellishly difficult to configure. Try and read the Exim documentation; you could do a university degree on it (I'm not kidding). When you can get an HTTP server like Cherokee which is easy to configure and has a nice web interface, do MTAs or groupware solutions need to be that hard? I'm aware that some people think "the Unix way" is to have lots of different interacting pieces of software (like maybe an SMTP MTA, POP3 service, webmail service, and overarching manager to tie them all together), but I think this is a situation where that just makes things a lot harder to deal with and one large software suite fits in much more nicely. So, I'm looking for good open source software suites that will run on Debian that: Combine (at least) SMTP, POP3, and IMAP Are easy(ish) to configure Have a nice configuration web interface or GUI Are not defunct projects I don't mind if it's groupware and offers calendaring too, but I would only be using the e-mail functionality for now. Another nice-to-have would be built-in webmail (if we're combining a bunch of functionality, why not?) Note however that I do NOT need Outlook support. I am not really looking for an "Exchange replacement drop-in". The suites I've found so far that seem to match the above criteria (and have appropriate licenses) are Citadel, Kolab, and Zimbra. I'd appreciate anyone who has experience with any of these giving me the pros and cons of them, such as how easy they are to configure and what their performance is like. I'd also appreciate any other suggestions for solutions that fulfil my criteria that I may have missed out.

• exchange server 2010 with multiple domains

  - by air

  i have one exchange server 2010, which is working fine with one domain. my exchange is working as follows pop3 collector collect emails from one master catchall account and then deliver to exchange server, this working perfect. now what i want to add another domain to same exchange, i have added new domain as trusted domain & email policy and this new domain email account works fine with internal emails. now what i have done, i again forward new email account to same catchall account. but if i send email from any other external email address email is bounce, i can see email receive by pop3 collector but bounce by exchange server. to make you more clear let me explain logic on which i am working. i have 2 domains 1. domain1.com ([email protected]) 2. domain2.com ([email protected] -->[email protected]) now on my machine with exchange server i have pop3 collector which collect all emails from [email protected] and forward to exchange 2010 server. all emails to domain1.com is working perfect but when i send email to [email protected] this email redirect to [email protected] perfectly but when exchanger server receive this email, it bounce. i have also study the url link text and follow the whole process but no success. i also check that my DNS/MX is working fine as the bounce message is going from my exchange server. EDIT the only problem is with accepted domain, as email come to exchange server then bounce back. i just try this today i create one user called test, then i goto his properties -- email there was only one email account [email protected] i try to send email to [email protected] from internet (email bounce) then again i go to test user properties -- email and Add one email [email protected] again u try to send email to t*[email protected]* from internet (email received) i think the only problem is with accepted domain but in hub transport , it shows accepted is there any way to check does domain is properly accepted or not in exchange 2010 server. Thanks

• Accessing an Exchange Server without Outlook

  - by Thomas Owens

  Is there a method of accessing an Exchange server that does not have IMAP or POP3 enabled without Outlook? It does not appear that Outlook Express supports Exchange (only IMAP and POP3).

• .Net Windows Service to monitor mailbox

  - by Brent

  Hi there, I need to create a .Net windows service to monitor a mailbox and process attachments (if found) on the emails and then delete the email from the server. I have two questions I'd like your thoughts on: POP3 or IMAP to connect to the mail server? Which POP3/IMAP library should I use. At this stage we're just doing a proof of concept, so a free one would be my preference. Cheers!

• Apache reverse-proxy intermittent error 113 - No route to host

  - by BonkaBonka

  I've got an Apache 2.0.52 server on CentOS 4 that front-ends a couple of App servers (mix of Jetty and Tomcat). Apache has a handful of virtual hosts configured like this: <VirtualHost www1.example.com:443> ServerName www1.example.com DocumentRoot "/mnt/app_web/html" SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP SSLCertificateFile /etc/httpd/conf/ssl.crt/server.crt SSLCertificateChainFile /etc/httpd/conf/ssl.crt/chain.crt SSLCertificateKeyFile /etc/httpd/conf/ssl.key/server.key SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0 RewriteEngine on RewriteRule ^/app1/(.*)$ http://app1.example.com:8080/app1/$1 [P,L] RewriteRule ^/app2/(.*)$ http://app2.example.com:8080/app2/$1 [P,L] </VirtualHost> However, I'm getting the following errors in the logs intermittently: [Fri Dec 04 07:19:41 2009] [error] (113)No route to host: proxy: HTTP: attempt to connect to 10.0.0.1:8080 (app1.example.com) failed I initially tried turning off IPv6, and that seemed to largely cure it, but I still have sporadic bursts of these messages.

I am completely lost as to how to proceed with troubleshooting this. =(

• Cannot send email outside of network using Postfix

  - by infmz

  I've set up an Ubuntu server with Request Tracker following this guide (the section about inbound mail would be relevant). However, while I'm able to send mail to other users within the network/domain, I cannot seem to reach beyond - such as my personal accounts etc. Now I have no idea what is causing this, I thought that all it takes is for the system to fetch mail through our exchange server and be able to deliver in the same way. However, that hasn't been the case. I have found another server setup in a similar fashion (CentOS 5, Request Tracker but using Sendmail), however it is a dated server and whoever's built it has kindly left no documentation on how it works, making it a pain to use that as a reference system! :) At one point, I was told I need to set up a relay between the local server's email add and our AD server but this didn't seem to work. Sorry, I know next to nothing about mailservers, my colleagues nothing about Linux so it's a hard one for me. Thank you!

• Connection refused after installing vsftp on Ubuntu 8.04 with fail2ban

  - by Patrick

  I have been using an Ubuntu 8.04 server with fail2ban for a while now (12+ months) and using ftp over SSH without any problems. I have a new user that needs to put files onto the server from an IP modem. I have installed vsftp (sudo apt-get install vsftp) and everything installed correctly. I have created an ftp user on the server following this guide.

• Postfix: How do I Make Email Aliases Work?

  - by Nick

  The documentation claims that I can add aliases in a file (like /etc/postfix/virtusertable) and then use the "virtual_maps" directive to point to it. This does not appear to be working, however. My mail is bouncing with: Recipient address rejected: User unknown in local recipient table; If I mail the user from the server using the mail command, it works. mail myuser The message goes through postfix and inserts itself in the Cyrus inbox correctly. When I use fetchmail to get the user's messages off a pop3 server, postfix fails. The user's email is "[email protected]", but it doesn't seem to be mapping correctly to "myuser", the cyrus mailbox name. /etc/postfix/main.cf myhostname = localhost alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = localhost relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all mailbox_transport = lmtp:unix:/var/run/cyrus/socket/lmtp #lmtp:unix:/var/run/lmtp virtual_alias_domains = mydomain.com virtual_maps = hash:/etc/postfix/virtusertable /etc/fetchmailrc et syslog; set daemon 20; poll "mail.pop3server.com" with protocol pop3 user "[email protected]" password "12345" is "myuser" fetchall keep /etc/postfix/virtusertable [email protected] myuser postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no config_directory = /etc/postfix inet_interfaces = all mailbox_size_limit = 0 mailbox_transport = lmtp:unix:/var/run/cyrus/socket/lmtp mydestination = localhost myhostname = localhost mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 myorigin = /etc/mailname readme_directory = no recipient_delimiter = + relayhost = smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_use_tls = yes virtual_alias_domains = mydomain.com Why is it ignoring my alias?

• Multiple static WAN IP addresses to single LAN subnet

  - by Jessy Houle

  Below is my home network topology. I currently have 5 static IP addresses, 3 of which are in use by 3 routers. These routers in-turn subnet internal networks and port forward. I use my SSL VPN appliance to remote home from work or on the road. At this point I can remotely administer my Windows Server. I know the network is setup wrong, I was matching existing hardware the best I knew how. http://storage.jessyhoule.com.s3.amazonaws.com/network_topology.jpg Ok this said, here is the problem... One of my websites on my Windows Server now needs to be secure (SSL using port 443). However, I'm already port forwarding port 443 to my VPN appliance. Furthermore, if I'm going to have to reconfigure the network, I would really like to be able to use the SSL VPN to remotely administer all machines. I mentioned this to a friend of mine, who said that what I was looking for was a firewall. Explaining that a firewall would take in multiple static (WAN) IP addresses, and still allow all internal devices to be on the same network. So, basically, I could supply my SSL VPN appliance it's very own static (WAN) IP address routing, and yet have it on the same internal network (192.168.1.x) as all my other devices. The first question is... Does this sound right? Secondly, would you suggest anything different? And, finally, what is the cheapest way to do this? I am started down the road of downloading/installing untangle and smoothwall to see if they will do the job, hoping they take multiple static (WAN) IP addresses. Thank you in advance for your answers. -Jessy Houle

• Juniper’s Network Connect ncsvc on Linux: “host checker failed, error 10”

  - by hfs

  I’m trying to log in to a Juniper VPN with Network Connect from a headless Linux client. I followed the instructions and used the script from http://mad-scientist.us/juniper.html. When running the script with --nogui switch the command that gets finally executed is $HOME/.juniper_networks/network_connect/ncsvc -h HOST -u USER -r REALM -f $HOME/.vpn.default.crt. I get asked for the password, a line “Connecting to…” is printed but then the programm silently stops. When adding -L 5 (most verbose logging) to the command line, these are the last messages printed to the log: dsclient.info state: kStateCacheCleaner (dsclient.cpp:280) dsclient.info --> POST /dana-na/cc/ccupdate.cgi (authenticate.cpp:162) http_connection.para Entering state_start_connection (http_connection.cpp:282) http_connection.para Entering state_continue_connection (http_connection.cpp:299) http_connection.para Entering state_ssl_connect (http_connection.cpp:468) dsssl.para SSL connect ssl=0x833e568/sd=4 connection using cipher RC4-MD5 (DSSSLSock.cpp:656) http_connection.para Returning DSHTTP_COMPLETE from state_ssl_connect (http_connection.cpp:476) DSHttp.debug state_reading_response_body - copying 0 buffered bytes (http_requester.cpp:800) DSHttp.debug state_reading_response_body - recv'd 0 bytes data (http_requester.cpp:833) dsclient.info <-- 200 (authenticate.cpp:194) dsclient.error state host checker failed, error 10 (dsclient.cpp:282) ncapp.error Failed to authenticate with IVE. Error 10 (ncsvc.cpp:197) dsncuiapi.para DsNcUiApi::~DsNcUiApi (dsncuiapi.cpp:72) What does host checker failed mean? How can I find out what it tried to check and what failed? The HostChecker Configuration Guide mentions that a $HOME/.juniper_networks/tncc.jar gets installed on Linux, but my installation contains no such file. From that I concluded that HostChecker is disabled for my VPN on Linux? Are the POST to /dana-na/cc/ccupdate.cgi and “host checker failed” connected or independent? By running the connection over a SSL proxy I found out that the POST data is status=NOTOK (Funny side note: the client of the oh-so-secure VPN does not validate the server’s SSL certificate, so is wide open to MITM attacks…). So it seems that it’s the client that closes the connection and not the server.

• Why can't I see all of the client certificates available when I visit my web site locally on Windows 7 IIS 7?

  - by Jay

  My team has recently moved to Windows 7 for our developer machines. We are attempting to configure IIS for application testing. Our application requires SSL and client certificates in order to authenticate. What I've done: I have configured IIS to require SSL and require (and tried accept) certificates under SSL Settings. I have created the https binding and set it to the proper server certificate. I've installed all the root and intermediate chain certificates for the soft certificates properly in current user and local machine stores. The problem When I browse to the web site, the SSL connection is established and I am prompted to choose a certificate. The issue is that the certificate is one that is created by my company that would be invalid for use in the application. I am not given the soft certificates that I have installed using MMC and IE. We are able to utilize the soft certs from our development machines to our Windows 2008 servers that host the application. What I did: I have attempted to copy the Root CA to every folder location for the Current User and Location Machine account stores that the company certificate's root is in. My questions: Could I be mishandling the certs anywhere else? Could there be a local/group policy that could be blocking the other certs from use? What (if anything) should have to be done differently on Windows 7 from 2008 in regards to IIS? Thanks for your help.

• _default_ VirtualHost overlap on port 443, the first has precedence

If you plan to use name-based virtual hosts, remember that they only work with your non-secure Web server. But not able to figure out how to run two ssl application on same server. Can any one help me?

• How can I "filter" postfix-generated bounce messages?

  - by Flimzy

  We are using postfix 2.7 and custom SMTPD (based on qpsmtpd) in highly customized configuration for spam filtering. We have a new requirement to filter postfix-generated bounces through our custom qpsmtpd process (not so much for content filtering, but to process these bounces accordingly). Our current configuration looks (in part) like this: main.cf (only customizations shown): 2526 inet n - - - 0 cleanup pickup fifo n - - 60 1 pickup -o content_filter=smtp:127.0.0.2 Our smtpd injects messages to postfix on port 2526, by speaking directly to the cleanup daemon. And the custom pickup command instructs postfix to hand off all locally-generated mail (from cron, nagios, or other custom scripts) to our custom smtpd. The problem is that this configuration does not affect postfix generated bounce messages, since they do not go through the pickup daemon. I have tried adding the same content_filter option to the bounce daemon commands, but it does not seem to have any effect: bounce unix - - - - 0 bounce -o content_filter=smtp:127.0.0.2 defer unix - - - - 0 bounce -o content_filter=smtp:127.0.0.2 trace unix - - - - 0 bounce -o content_filter=smtp:127.0.0.2 For reference, here is my main.cf file, as well: biff = no # TLS parameters smtpd_tls_loglevel = 0 smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache smtp_tls_security_level = may mydestination = $myhostname alias_maps = proxy:pgsql:/etc/postfix/dc-aliases.cf transport_maps = proxy:pgsql:/etc/postfix/dc-transport.cf # This is enforced on incoming mail by QPSMTPD, so this is simply # the upper possible bound (also enforced in defaults.pl) message_size_limit = 262144000 mailbox_size_limit = 0 # We do our own message expiration, but if we set this to 0, then postfix # will try each mail delivery only once, so instead we set it to 100 days # (which is the max postfix seems to support) maximal_queue_lifetime = 100d hash_queue_depth = 1 hash_queue_names = deferred, defer, hold I also tried adding the internal_mail_filter_classes option to main.cf, but also tono affect: internal_mail_filter_classes = bounce,notify I am open to any suggestions, including handling our current content-filtering-loop in a different way. If it's not clear what I'm asking, please let me know, and I can try to clarify.

• Apache Named Virtual Hosts and HTTPS

  - by Freddie Witherden

  I have an SSL certificate which is valid for multiple (sub-) domains. In Apache I have configured this as follows: In /etc/apache2/apache2.conf NameVirtualHost <my ip>:443 Then for one named virtual host I have <VirtualHost <my ip>:443> ServerName ... SSLEngine on SSLCertificateFile ... SSLCertificateKeyFile ... SSLCertificateChainFile ... SSLCACertificateFile ... </VirtualHost> Finally, for every other site I want to be accessible over HTTPS I just have a <VirtualHost <my ip>:443> ServerName ... </VirtualHost> The good news is that it works. However, when I start Apache I get warning messages [warn] Init: SSL server IP/port conflict: Domain A:443 (...) vs. Domain B:443 (...) [warn] Init: SSL server IP/port conflict: Domain C:443 (...) vs. Domain B:443 (...) [warn] Init: You should not use name-based virtual hosts in conjunction with SSL!! So, my question is: how should I be configuring this? Clearly from the warning messages I am doing something wrong (although it does work!), however, the above configuration was the only one I could get to work. It is somewhat annoying as the configuration files have an explicit dependence on my IP address.
