README (Warlord)
================

The Warlord patch is the successor of Russell Nelson's 
and Charles Cazabon's "qmail-smtpd-viruscan-patch".
It realizes a robust and efficient base64 scanning.

Features:

- The whole message is scanned for embedded base64 attachments.
- The first characters of the identified attachments
  are checked against the strings found in badmimetypes.cdb,
  if the environment variable BADMIMETYPE is present.
- The whole content of all base64 attachments
  are checked against arbitary strings provided in 
  badloadertypes.cdb. In order to make the search efficient,
  the required environment variable BADLOADERTYPE has
  to be supplied with the first character of the content
  of the badloadertypes.cdb.
- Customized SMTP 554 reply messages can be defined and used 
  via the environment variable REPLY554.

By means of the programs qmail-badmimetype and qmail-badloadertype, 
the databases can be modified by need on the fly.

See man qmail-smtpd, qmail-control, qmail-badmimetypes, and 
qmail-badloadertypes.
