In one of my installations, this is my solution. Start 'qmail-start' with special 'qmail-maildrop' wrapper (see below) instead of procmail or './Maildir' etc:

/usr/sbin/qmail-start |/usr/sbin/qmail-maildrop

/usr/sbin/qmail-maildrop: ----- s n i p ----- #!/bin/sh

export MAILDIR=$PWD export TMPHOMEDIR=$MAILDIR export HOME=$MAILDIR /usr/bin/preline /usr/bin/maildrop && exit 0

# check if maildrop returned EX_TEMPFAIL (75) [ $? = 75 ] && exit 111

# otherwise return a permanent error exit 100 ----- s n i p -----

/etc/maildroprc: ----- s n i p ----- # Global maildrop filter file

# MAILDIR is set in the maildrop wrapper # to the same as mail message store import MAILDIR DEFAULT="$MAILDIR" DEFAULT_DEF="$MAILDIR"

# Just incase user don't have a shell SHELL="/bin/sh"

# Mail file will be user and group writable UMASK=007

MAILDIRQUOTA="0"

import HOME import RECIPIENT import HOST import LOCAL

if ( $SIZE < 262144 ) { xfilter "/usr/bin/spamc -f -u $RECIPIENT"

if (/^X-Spam-Level: SSSSSSSSSS*/) { # SPAM scored higher than 10, so let's just toss it! to /dev/null exit }

if (/^X-Spam-Flag: *YES/) { to /var/mail/spam exit } }

# Local variables: # tab-width: 4 # End: ----- s n i p -----

The last 'to' entry should probably (I'm testing this now) read:

to !spam...@domain.tld

This user is an ordinary pop/imap user with the mail directory as '/var/mail/spam'...

Other than those two (tree) things, I can't remember if I did anything special...
