Here's my mailfilter ... Running from .qmail using vpopmail 5.3.4. Each user gets their own mailfilter and .qmail file. I suppose I could have a global system mailfilter and turn it on and off by way of .qmail, but then would have to do userdir lookups via vuserinfo which would cause a postgresql call ... Not that it would make a big difference, but figure I would trade database load for disk space.

Hope this helps.

/*** begin .qmail file ***/ |maildrop mailfilter /*** end .qmail file ***/

/*** begin mailfilter file ***/ import EXT import HOST import HOME MAX = 15

if ($SIZE < 262144) { xfilter "/usr/bin/spamc -p 1783 -f -u $EXT@$HOST" }

if ((/^X-Spam-Status: Yes, hits=![0-9]+\.[0-9]+!.*/:h && $MATCH2 > $MAX)) { exit }

if ((/^X-Spam-Flag:.*YES/)) { `test -d ./Maildir/.SPAM` if( $RETURNCODE == 1 ) { `maildirmake ./Maildir/.SPAM;chown -R vpopmail.vchkpw ./Maildir/.SPAM` } to "./Maildir/.SPAM/" }

to "./Maildir/"
