A very effective method of filtering is to look for the List-ID: header.
Most mail software won't display it to you without persuasion, but
for freebsd-questions at ... it looks like this:

[...]
X-Mailman-Version: 2.1.5
Precedence: list
List-Id: User questions <freebsd-questions.freebsd.org>
List-Unsubscribe: <http://lists.freebsd.org/mailman/listinfo/freebsd-questions>, 
	<mailto:freebsd-questions-request at freebsd.org?subject=unsubscribe>
[...]

Mailing lists should nowadays include a List-ID: header in the mails they
send out.  [RFC 2919 if you're that interested] Sorting messages based on
it is, I find, generally the most accurate way to classify them correctly.

It's very easy to do in procmail -- too obvious to bother giving an
example. In thunderbird, you have go into Tools:Message Filters, then
hit New to create a new rule, then choose 'Customize' from the 'Subject'
pull-down.  Unfortunately squirrelmail is not a software package I know
much about, but I'd expect any reasonably competent e-mail client to
be able to filter on arbitrary mail headers without too much trouble.
