The mailing lists are checked by the "is_mailing_list_message" block based
on header match:
 re.match(".*(majordomo|listserv|listproc|netserv|owner|bounce|mmgr|autoanswer|request|noreply|nobody).*@",
self.msg.getheader("From",''), re.IGNORECASE)):

Not really, If we properly build a set of queries to check the
possibilities, I think the database could be faster in an setup with LOTS
of entries in the list (ie: global company white/black list), regex would
have to check all entries and a db query should return a single response.
(yes || no)
At the moment I can think of 3 queries only in this order:
1- an exact match on a wildcard domain, *.domain.name
2- word or frase match anywhere in the subject line.
3- Exact macth on an email address

With a database we only need a single indexed entry for an address for all
users and all domains hosted. The individual user list will have a single
index hopefully smaller in lenght and faster to search.
