Thanks everybody for replies.
Actually I've got about 100 users and a flow of about 2500 e-mails per day. I 
think that one (or two) combined servers can do the work quite well, but just 
to get some more opinions, what is the precision of a software like 
spamassins?
Because if the software can be very precise it can worth learning it for sure!
