I have moved from one server provider to another porting all my domains and services. Everything went smoothly at first sight, but I realised now that i am having some problems with dovecot/postfix.
First problem: In the webinterface (Roundcube) I see all old mails with the correct timestamp, when getting them on a mailclient, I always see 5th May 2015 (one day after server has been moved) as date.
Second problem: I seem to not be able to send and receive mails via IMAP. I do not get an error (ill post the logs later in this post), it seems as if the mail has been sent.
Third problem: Logfile is spammed with this errors: warning: 9C42A2408E2: virtual_alias_maps map lookup problem for root@dirty-harry -- message not accepted, try again later
(dirty-harry is my servers name!).
I have googled all of these problems, looked over my configurations again but cannot find anything that would solve my problem.

mail.err and mail.warn are empty.
I would be very greatful if someone could have a look at it! Thank you!

I have found the solution now with the guys here at Server Fault.
There were two problems going on:
Why wasnt I able to receive Mails?
I migrated the server and updated the DNS A records, but forgot to update the mx records, so the old server was still receiving the mails, where postfix and dovecot were still running. Updating the mx record solved the issue.
Why wasnt I able to send mails and got the log spammed?
I had a typo in the postfix database name. Fixing that resolved that issue.
