Mail.log errors

Could someone help me to find out what problems do I have :S
Those are the errors what my log report:

Seems like we both have the same problem with postfix/trivial-rewrite. Have you found a sollution yet?

Bro. I have same problem with my postfix. Have you been able to resolve it? Please let me know how you did resolves it.

Might be a different problem. But after the latest apt-get upgrade on my 6.06 server last week, I got lots of

postfix/trivial-rewrite[3625]: fatal: mysql:/etc/postfix/mysql_alias.cf(0,100): table lookup problem

errors because the mail user couldn't log in to mysql anymore. I had to go into mysql as admin and grant the privileges again.
