Postfix refuses to accept emails from the internet

Tue Apr 7 11:36:16 CEST 2015

Ok, found it. For some reason the wrong port was in the /etc/postfix/main.cf for the content_filter option.
I've corrected it now and this error appeared.

But now I got a really strange error, which I encountered already yesterday and do not have any clue at all :(
Here the log from /var/log/mail.log - as far as I can see this indicates that everything runs fine?

But for some reason, the mail is not dropped to the inbox of the user :(
Any help would be highly appreciated!

Hi @All

At first I was able to solve the postfix issue - it was simply a matter of adding the right LDAP queries to local_recipient_maps etc.
The mailserver did start working properly yesterday for about 8 hours.

After adding a few more accounts in the Kolab Webadmin things suddenly stopped working. All I can see now is the following in the /var/log/mail.log:

Any Ideas?

Nearly everything works. Only postfix refuses to accept emails from

What is your postfix  main.cf?

He posted it before.
