FIAIF blocks local postfix

[Sebastian Feldmann]

Hi there,

first of all, i'm a networking n00b
i'm trying hard to improve my linux serveradmin/networking skills but there are still so much things i just dont know.

We are running a little website on our server (www.moviegod.de).
Our serveradmin has quit a little while ago, so i have to do this things on my own

On our website is a "standard" contact form.
The user submits the form, the webserver sends a mail via the mailserver postfix.

This works just fine for any mail addresses but not for our own *@moviegod.de addresses.

my FIAIF config for outgoing requests looks like:

==================IFAIF===================
OUTPUT[0]="ACCEPT ALL 0.0.0.0/0=>0.0.0.0/0"

The Postfix mailq looks like this
The mails are scheduled but not delifered

==================POSTFIX===================

(connect to mailserv.regfish.com[79.140.49.126]: Connection timed out)
info at moviegod.de

The log shows the following

I googled something about MARTIAN and Firewall but didn't came up with a real solution

Do you have some hints for me?

best regards
Sebastian
