So you suspect Hotmail thinks there's something spammy about Mailman?
Maybe you can test yourself including things like the Mailman footer and
any URIs that might be dirtylisted to work out what factor is affecting
Hotmail's "spam confidence level".

Connecting IP 126.96.36.199 seems clean.

SURBL/PhishTank says proxad.net is a domain abused for phishing, but
that shouldn't be a significant problem.

Confirms problem is not SPF or DKIM.

OK, so Forefront thinks the message is "SPM" with a Confidence Level of
5 (suspect spam).

Not regarded as bulk or phishing, so seems like a false positive from MS
Forefront/Cloudmark. How to report this? Well, maybe your recipients
marking as not spam and moving the message to the inbox will help a
little. Or any recipients using a paid MS service like Office 365 may
be able to raise a support ticket. Or there's a submission form for
Cloudmark at https://www.cloudmark.com/en/support/cloudmark-authority.
If none of that works, try to find someone at Hotmail or microsoft.com
who might help.
I don't think it's particularly Mailman related.
