postfix can use milters, eg call dspam in lmtp/smtp and deliver back 
via lmtp/smtp, then in postfix use milter-regex to drop mails that is 
added with dspam headers as spamming, or use dovecot-sieve or another 
sieve enabled lda

here i use roundcube to manage sieve scripts and i am happy to see that 
dovecot-antispam fullend it :=)

training is just a matter of move mails from ham folders to spam 
folders, or the otherway move spam to ham folders if that ever happend, 
thats why there is no support for dspam in postfix other then 
signing/quarantine imho, else one loose mails if fp

route i have here is:

postfix > clamav-milter if virus reject in milter
         > amavisd-new > spamassassin if spam tag in headers
         < amavisd > postfix < just send it back into postfix queue
         > postfix > dspam (so dkim signined emails is valid in 
spamassassin)
         < dspam > postfix ready for delivery in dovecot now
         > postfix >
                   > dovecot lda > sieve rules

amavisd does not make virus scanning since i hate have virus quarantine
