I read postfix.sum daily and it looks okayish to me. 76% was rejected 
yesterday due to greylisting, RBL or unknown receipient. Please explain what 
I should look for.

installed in a very non-intrusive way. When postfix is properly integrated 
with kolab I will happily ditch my distributors postgrey and use the one of 
kolab instead.
