Postfix refuses to accept emails from the internet

[Marco Betschart]

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:

Apr  7 11:08:21 alex postfix/qmgr[2794]: 913B89A004: from=<marbetschar at me.com>, size=1306, nrcpt=1 (queue active)
Apr  7 11:08:21 alex postfix/error[3093]: 913B89A004: to=<betschart at mandelkind.ch>, orig_to=<marco at mandelkind.ch>, relay=none, delay=1167, delays=1167/0/0/0.01, dsn=4.3.0, status=deferred (unknown mail transport error)

Any Ideas?
