Or do with .mailfilter files for the imap users.

in maildroprc:

xfilter "/usr/bin/spamc"

..mailfilter for the imap users:

if (/^X-Spam-Status: Yes,/)
{
to "./Maildir/.Spam/"
}

Everything will be scanned for spam and marked. If there is a .mailfilter
file, it will be run and spam will be delivered to the Spam box. All other
mail (regardless of the user) will be delivered to the inbox. This avoids
having to spawn a directory existence check for every email.
