Recently I do get some Mailman mail at my Gmail address, and I've
never seen it in the Promotions folder. Nor have any of the xemacs
subscribers I've talked to. But these are all programming-related
lists; it may be that Gmail's "AI" realizes that there's no way this
is a sales pitch.
It occurs to me now that if someone has a "Forums" tab, I would expect
Mailman mail to got there if and only if Mailman uses the RFC 2369
headers (possibly with the exception of List-Unsubscribe) and/or the
RFC 2919 List-Id header. You can turn these off.

That I can't help with. As Mark suggests the "Precedence: bulk"
header may confuse some MUAs like Gmail.

There are no standards for classifying mail, really. I would say
Gmail is wrong, though, because confirmation emails are very easy to
recognize, and very urgent to most users (consider password reset).
Mailman might be able to help by trying to mimic the typical password
reset confirmation mail.
The problem may be that phishers often use mail that looks like a
confirmation mail, but then you should get a phishing warning. Or
maybe the issue is that Mailman allows confirmation by email, where
most password confirmations require going to a specific web address.
