# If you want to have Anti-spam support, just install spamassasin and make
# it alter the subject of the messages and edit /var/qmail/bin/scanmail.sh
# and change SPAM=no to SPAM=yes

# If you want to be able to extract more compressiontypes during the virus
# scan install  unrar, unarj, zoo, lha, tar and gzip
# and put the right path to them in /var/qmail/bin/scanmail.sh.

# Now edit /var/qmail/service/init.smtpd
# uncommend the following the:
# #export QMAILQUEUE='/var/qmail/bin/qmail-spamc'
# Line.

# That's it, you are set now.
