Hi all,
I got this patch from CERT (from Sendmail). Can somebody tell me
where to put it in my sendmail.cf on a 3.1-Release system?
Thanks -George
--------------------------------------------
This will work for all versions of Sendmail 8.9 and Sendmail Pro, and all
commercial sendmails based on 8.9. We believe, but I cannot guarantee that
this includes Solaris 7 and FreeBSD 3.x.

LOCAL_RULESETS
# Kludgey Melissa virus checking routine.
# Just need enough of a pattern to match.
# Instructional note:
# The format for the rule is
# RExactly the thing you want to quote
# No quote marks, no tabs, absolutely nothing in paretheses (like
this,
# they're considered comments and will be removed before they get to
# the rules). After the exact thing, then a tab, and the $#error.
# Note, the $* matches anything, so it's useful for wildcarding.
# This also scans all messages with Subject: headers and invokes a
rule,
# so there is a performance hit.
