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
# parentheses (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.
