Mailman can do this in a few different ways, all with standard list
configuration settings available to the list owner.

One possibility is 'topics'. You could have a list with several defined
topics like 'Sacramento'. You define regular expressions to be matched
against the message's Subject:. These can be simple like

a Sacramento topic with a regex of 'sac'
a Washington topic with a regex of 'wash'

and so on. Then, by default, a user gets all messages, but if she
subscribes to the Sacramento topic and also elects to receive posts that
match no topic, she will receive posts whose Subject: contains ...sac...
and those whose Subject : matches none of the topic regexes (keywords),
but not posts with ...wash..., etc. in the Subject:

Other ways to do this are umbrella lists and sibling lists.

Archiving is a list option which is generally on by default, but easily
turned off.

Mailman can add a header and/or a footer to each message with any text
you want.

I think Mailman can do what you want. We are here to help.
