    Dovecot just does pop/imap _after_ the mail is delivered to mbox or Maildir/...

 A simple way to do things is postfix->procmail->spamassassin . It works on a per
user basis the . And you can tweak spamassassin to sort by score :

 With a bit of training ( sa-learn  --ham mbox  /  sa-learn --spam spam   say 
once a month ) you quickly get down to a few false positive/negative per year.
All the configuration is done in .forward and .procmailrc

Not sure how to do it with Maildir though ...

  Ah - but there are so many "standards" .......
