Hi guys,

I want to run my own SMTP server on Mandriva Linux. I want to setup postfix. I went through the installations and it seems to be working just fine:

[alireza@localhost ~]$ telnet localhost 25
Trying 127.0.0.1...
Connected to localhost (127.0.0.1).
Escape character is '^]'.
220 server1.alirezanit.net ESMTP Postfix (2.3.3) (Mandriva Linux)
ehlo localhost
250-server1.alirezanit.net
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH LOGIN PLAIN
250-AUTH=LOGIN PLAIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
quit
221 2.0.0 Bye
Connection closed by foreign host.


I setup the SSL stuff and everything. Below you can see the main.cf file contents.

The problem is, when I try to send an email using postfix, it doesn't go through. It gets queued and gets stuck there:

[alireza@localhost ~]$ mailq
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
1CD3C8C077 497 Fri Jun 1 00:18:37 ***@****
(connect to barracuda.sfu.ca[142.58.101.50]: Connection timed out)
***@****

1077E8C07D 659 Fri Jun 1 00:20:51 ***@****
(connect to barracuda.sfu.ca[142.58.101.50]: Connection timed out)
***@****

16CD08C07E 654 Fri Jun 1 00:21:20 ***@****
(connect to barracuda.sfu.ca[142.58.101.50]: Connection timed out)
***@****

-- 2 Kbytes in 3 Requests.
[alireza@localhost ~]$


NOTE: ***@**** are in place of actual email addresses.

Can anybody tell me why this isn't working? Maybe I should relay my messages to my ISP's SMTP server? If yes, can somebody tell me how, plesae?

Thank you

I don't know about the mdk specific setup or patches, but I think you should explore the 2 following tracks to solve your problem :

1) set the "myorigin" parameter to something that exists on the internet
2) set the "relayhost" parameter to your ISP smtp server

Also, make a "tail -f" on your postfix log file to see what's happening when it tries to send mail to the outside world.

If you still have problems, go to http://www.postfix.org/documentation.html and read the documentation there. It's wonderful and should answer all your questions. If it still doesn't work, well read again the docs...
