Newer versions of mailman don't do this by default (or is it just
Debian?), and instead encapsulate the original email inside a
wrapper. To avoid changing the subject, edit either
/etc/spamassassin/local.cf and add/change:

    rewrite_subject 0

man Mail::SpamAssassin::Conf has more details.

In short, from Mail::SpamAssassin::Conf(3pm): the algorithm is to
track the long‐term mean score of messages for the sender. So if a
person has a history of non-spam, the he's gets a lower score in
future.
