Mail Filter Recommendations

[Asai]

Greetings,

We've been using Amavis for a number of years, but it seems to not be 
doing what we need it to be doing regarding spam filtering.  e.g. I 
can't seem to get it to learn bayes data on a per user basis.  We have 
our spam filters turned up so high ( kill level 3 ) for some users it 
just seems like we're doing something wrong.  I have deleted the Bayes 
data before and let it rebuild, but it doesn't seem to make sense that 
we've got all this crazy spam,  some of which gets caught and some 
doesn't even though it's the exact same spam (or nearly the same).  Is 
Amavis to blame here?  Does it get in the way of Spamassassin running as 
it should, or is it more just configuration problems on our part?

Thanks.
