I posted the whole result.
But I do have an A record for zimbra.schuelerunion.at

Traceroute, Ping, Domain Name Server (DNS) Lookup, WHOIS, and DNS Records Lookup shows the following result:

Now the A record definitly works.
But the mails are still queued in the referred queue with the error "mail transport unavailable".

If I do a queue flush I have pages of this errors:

The postfix seems to work right, but there seems to be a problem at the delivery from postfix to the mailbox?

Here is a mail that came from outside and got deferred:

While making a fresh install of 5.0.2 and restoring a backup made before I found one very strange behaviour: The delivery to new mailboxes works, the delivery to restored mailboxes results in the error above.

Can anyone help?

Contacted me over skype - ok, so 2 problems found:
1) When changing platforms it's a good idea to use the methods listed in /blog/archives/2007/10/moving_zcs_to_another_server.html
-You need to use the same zimbra version for the operating system switch
-So the 4.5.5 > 4.5.6 hurt a little in the first place...
2) & on top of that the servername changed...

[zimbra@zimbra ~]$ zmprov ga olduser@schuelerunion.at | grep Transport
zimbraMailTransport: lmtp:zimbra.it-swat.net:7025
[zimbra@zimbra ~]$ zmprov ga newuser@schuelerunion.at | grep Transport
zimbraMailTransport: lmtp:zimbra.schuelerunion.at:7025

He's working to restore the accounts right now, then we'll fix the transport the hard way...

For future reference, directions for servername changes are in are in ZmSetServerName - Zimbra :: Wiki

[Klug]

I do have to learn all zmprov options...

I'm not changing server but upgraded from 4.5.10 to 5.0.2 here is my post

Deferred Email - Content Filter: Undefined

But the problem came back again. So my fix helped, but something else is going on.
