List posts are sent with Precedence: list. Notices from Mailman, e.g.
held message notices to an admin, invitations and welcome messages to
users, password reminders, etc. are all sent with Precedence: bulk.

Prior to Mailman 2.1, everything was sent with Precedence: bulk, even
list posts.

Comments in the Mailman 1.0 code say

# semi-controversial: some don't want this included at all, others
# want the value to be `list'.

RFC 2076 (Feb 1997) says the Precedence: header is "non-standard,
controversial, discouraged". See the RFC
<http://www.rfc-editor.org/rfc/rfc2076.txt> for the precise definition
of these terms.

We probably shouldn't be adding it at all, but as to why, other than the
above code comment, some things are sent with Precedence: bulk you'd
have to ask John Viega or someone with more knowledge of the history
than I have.
