I have these things in the config for my "lean-mean-contentfilter"
(that is included with Zmailer):
# Viruses in attachments
B^Content-Type: application/octet-stream;^ *NAME=*.scr
B^Content-Type: application/octet-stream;^ *NAME=*.pif
B^Content-Type: application/octet-stream;^ *name=*.scr
B^Content-Type: application/octet-stream;^ *name=*.pif
B^email address. This email address will be expiring.
Note that the whitespace in the lines 5-8 *must* be TAB.
This checks all mail attachment viruses so far (but it can be easly
fooled, of course, if the virus writes specifically wants so).
