I run dist-upgrade from Debian Lenny to Squeeze. Three days monitoring & fixing all *million* little errors (mostly php and apache related) and seems that everything works again like a Buick!
Only errors that I found now is from mail.log

Many installation guides on the Internet says that you have to remove libio-socket-inet6-perl
but does not describe why? (I got that library installed on my system).
So far any hit from google does not have solved these error messages, however mail server works; I can receive and send mails via It just fine.
I have not made any changes to postfix, spamassassin, amavis or clam-av configurations on this machine, all have been worked without those error messages on Lenny and works now but with errors on mail.log
I'm guessing that I need to add/tune some configuration "things" or completely change things but can't find anything that could cause the errors so it's hard to try or change anything..
Could someone give me a hint or two?
