Apr 24, 2009I am trying to set up a mail server on centos5 using sendmail and dovecot, and eventually spamassassin and some antivirus filter as well. I'd also like to get the proper secure auth mechanism set up at some point too. But for starters, I've been having a lot of difficulty trying to even connect to the mail server from a client computer in the local network. I installed Eudora on the client and after some tweaking in dovecot I was able to connect to the mail server, but then when I try to send an email I get a "connection refused" error, with nothing being logged on the server that I can see.
The last time I set up a mail server was Fedora Core 2, so the configuration files have changed a bit to say the least, and I can't really refer back to those to set up this new server. Does anybody know of a good step-by-step doc on getting the mail server going? I've read the man pages and other various readme's, but these really only list out the available options with no really good explanation of what needs to be done to get the mail server going. If there isn't a full write-up on how to do this, I'll put something together when I'm finished so others can use it in the future.

Jul 25, 2011For about a week now I've been seeing mass attempts to relay through postfix and login to dovecot from the same 2 addresses, none are successful due to how postfix/dovecot are configured and I wouldn't be overly worried but my isp have picked up on it and are nagging at me
What ways do people go about just dropping connection attempts from offending addresses/ranges when stuff like that happens? An ideal thing would be something that detects repeated failed attempts from a host or range and subsequently ignore/ban them, perhaps for a specified length of time, something along the lines of denyhosts and fail2ban for ssh would be great Don't know if there's anything out there or just a plain tried and trusted method anyone might use for stuff like this, if not a hint on the most appropriate way to go about it 'manually' would do
OpenSUSE Network :: Telnet Does Not Work In IPv6 Test Environment
Aug 27, 2010In an IPv6 test environment I have installed an openSUSE 11.2 system. I have also installed telnet and it works with IPv4 (I can open a session from a Windows console with "telnet ipv4addr").
If I try to open a session with "telnet ipv6addr" I get the response: "Connecting To ipv6addr. Could not open connection to the host, on port 23: Connect failed".
Does the telnetserver support IPv6 or did I something wrong?

Apr 18, 2011I've configured postfix on my linux server. For the most part, I got everything working (IMAP, apache, etc) but for some reason, I can't get postfix to work remotely. Postfix works locally to send mail. E.g. when I telnet locally to port 25. However, when I try to telnet from outside, the connection closes almost immediately. I've looked at various configuration options and tuning enhancements but found nothing helpful. Here is my config:

Server :: Courier Or Dovecot For IMAP?
Mar 18, 2011Does anyone know if there are only personal preferences between the two IMAP servers or does one of a slight advantage over the other? I've used Dovecot only in the past but my package manager loads tons of MySQL libraries with Dovecot which is a problem since that's not authorized on my server right now. I can either install it from source or try another application like Courier.

Server :: Postfix / Dovecot Help On New Setup
Mar 20, 2011CentOS 5 box was just setup to replace a crashed old one. I have postfix.admin installed and working, added users (confirmed from mysql command line) and can login using telnet server pop3 with the user information. The problem I am left with is just receiving mail. I have both squirrelmail and roundcube installed, and can also authenticate using both (/var/log/maillog shows);From either webclient I can naturally send mail out and both yahoo and gmail client confirms, yet a reply shows nothing, and nothing ever shows in the maillog. Firewall is shut down but I don't know postfix enough to see how to test, or is something else grabbing the mail.
I can provide anything necessary, just let me know what. As I see it (just so far) Postfix should be the server that answers and receives the mail, dovecot is more the pop/imap the client would use, so I think it's a postfix issue. If so, can I turn up the debugging, etc. but again, I think all mail received should appear in the maillog file 1st as I see the outbound mail go fine!

Jun 3, 2011I'm working on setting up access for our developer via Telnet, we are on a local network behind a physical firewall. I set up the standard Telnet service for Fedora15 and from localhost I can login via any user and root.... However I cannot login from another terminal on the LAN, even though I can ping and FTP to the fedora15 box. I added the firewall rules for telnet, that did not work, so I disabled the firewall, still cannot get a connection via port 25. I feel either port 25 is closed in another manor or the telnet is restricted to the localhost.
Also I cannot login to root to configure the Firewall Desktop GUI, only standard users, is this an issue? I also cannot login to the console as root even though I use the correct password.I can only su to root and sometimes it is a PITA. There must be some settings to clear these issues up...
Server :: Cannot Telnet To 25 But Can Do It To 22
Nov 9, 2010I just setup a server using Ubuntu 10.04LTS Desktop edition. I am a novice in these things. I was able to setup the SSH server and it works from outside my LAN quite well. I can telnet to it also with 22. I have then setup an email server. I can do telnet to it from the server itself but from the internet it just times out.
I did netstat -nlp and it shows that it is listening to port 25. I have port forwarding for 25 enabled on the router. I cleaned up all the rules of iptables and iptables -L shows everything is accepted.

Server :: Dovecot Mailserver Sending But Not Receiving?
Jan 22, 2011I have followed the guide for "The Perfect Server - Debian Lenny (Debian 5.0) With BIND & Dovecot [ISPConfig 3]" and all is well, except.
I can send mail (to GMail) from commandline. I can send mail (to GMail) from any of the domains configured in ISPConfig3 through SquirrelMail (how ever terrible that looks, but functions) or IMAP/POP.
but....
I can't receive mail (from GMail) on any of the domains configured in ISPConfig3 in SquirrelMail or IMAP/POP.
I have my domains configured with proper MX records (just like I have them configured at work). I have all ports (80, 143, 110, 25, 22, etc) forwarded on my router that are needed.
I can Telnet to localhost and all checks are fine. I can send and receive from and to local domains on the same server, which makes sense. but
I can't Telnet from any external server to my server behind NAT.
Conclusion:
I figured it MUST be a network/port-forwarding problem as the external Telnet requests fails to my machine on port 25.
Tested my router if it would let met communicate through port 25 and it would.
So it must be my ISP, as I read in different posts.
Question:
Maybe I'm a n00b, but in all other posts the problems were with receiving AND sending.
My ISP responded that port 25 is blocked because of spam issues.
But I can mail (and even spam if I would like to) to external domains while I didn't do anything weird to make that happen.
The only thing I wish for is to receive mails and if you'd ask me, port 25 would be solely for outgoing mails, not for incoming mail deliveries throught MX?
An ISP surely wouldn't disable their customers in having a mail-server for incoming mails, as long as they would send out through their own smtp server to make sure they wouldn't spam the world?

CentOS 5 Server :: Dovecot Postfix POP Not Responding?
Jan 2, 2011I am running CentOS 5.2 on a server here in my home. It runs Dovecot and Postfix and also serves as a website host for a small website of mine. Everything works fine. POP, SMTP, Webmail, WWW, all works great and has for ages.Here's the issue. I recently reinstalled a clean copy of Windows 7 on a workstation in my home onto a new harddrive(I still have the old drive int he machine so I can boot to it as well). I setup the Windows Live Mail client to send/receive mail with my mail/web server. However, it won't connect to the POP server on my server machine.Here's the kicker. If I boot to the old harddrive that is running Windows 7, it connects fine to my mailserver and can send/receive just fine. I've checked, rechecked and rechecked and all mail settings on the mail clients on both drives are identical.
Note: The installations of Windows 7 on both drives is identical. Same computer name/ same credentials, same IP, etc. However, as I stated, I can send/receive email with my server if I boot to my old drive, but if I boot to my new drive, I cannot send/receive.
