Connection refused

[bojan.sliskovic]

Hello, I am showing all piler statuses green (OK), piler is listening on 0.0.0.0:25. I set the hostname fqdn to piler.mydomain.intra and the MTA resolves it ok. However when I try to send email to [e-mail], in the postfix log I see dns=4.4.1. status=deffered (connect to piler.mydomain.intra[11.22.33.44]:25: Connection refused)

I also tried to telnet from Windows machine, and it connects, but gives 502 command not implemented to HELO or EHLO. Then I tried telnet from linux machine, and it went ok. I was able to send email, and piler processed it. THEN I tried telnet from the linux server that has the MTA, and got connection refused over 25

I am not sure what is the problem?

EDIT: piler 1.1.0, build 884

Thx for your help!

Show me the piler logs, eg. /var/log/maillog. Also it's worth to check "ngrep -X port 25" on the piler host to see what's going on when you try to send an email from postfix.

root@xxx:/var/log# netstat -plntu | grep :25 tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 3173/piler

ngrep -X port 25

22.22.22.22 is piler host

T 11.11.11.11:25 -> 22.22.22.22:56377 [AP] 220 mail.server.com ESMTP Postfix..

T 22.22.22.22:56377 -> 11.11.11.11:25 [AP] QUIT..

T 11.11.11.11:25 -> 22.22.22.22:56377 [AP] 221 2.0.0 Bye..

/var/log/mail.log

basically this repeats:
