The spambouncer script makes the same incorrect assumption that
the EarthLink SPAM stuff makes, which is that any mail not explicitly
addressed to you is SPAM.  In other words, they expect mailing lists
to violate the draft RFC that prohibits header rewriting by mailing
lists, and they expect all mailing list servers to eat the overhead
of expanding each message to a single recipient message, instead of
sending the messages in bulk if the destination domain is identical.

At least the spambouncer script can be modified to respect the
Sender: header, which EarthLink fails to respect in their list of
allowed senders.  This is pretty much how you should modify the
spambouncer code to handle mailing lists (and how EarthLink should
modify their anti-SPAM system, as well, but probably won't).

Filter mails from FreeBSD mailing lists with List-Id: header in procmail 
before spam checking or filter by an different header like Sender.

This works well under kmail with spamassassin.

Many anti-spam packages need to be tuned to avoid classifying non-spam
messages as spam.  Depending on the software, sometimes it isn't
possible to avoid a significant false positive rate, but a good spam
filter (e.g. bogofilter) is one that doesn't have this characteristic.
