I'm having very good results with this rule. I'm scoring it at 5 with
no false positives. The high negative score for a legitimate looking
List-id will file it into my List/Unknown folder for new lists and for
any spammers trying to abuse this, so it's not a problem for my
personal filtering.
# a properly-formatted List-id looks like a correspondent

i would like developpers to begin make use of
Mail::SpamAssassin::Maillist.pm
if it exists, there is to many definations on maillists already in rule
sets, and non use maillist.pm
