So you must mean your local spamass is marking it as spam.
Love it! It immediately reminds me: In my accounting, "Assiniboine Credit Union" is coded as "AssCrU".

Ultimately the signed messages get screwed up by the mailing list. The headers make that pretty clear and spamassassin marks the message ‘X-Spam: Yes’ when further below you see another instance validate the original receipt.
X-Spam from the MUUG server says it passes ok. So you must mean your local spamass is marking it as spam.
Mailman should not touch the body, and the headers that are marked ("h=") you should be able to configure to ensure they don't include any that mailman modify.
Hmm... maybe that means Subject: should be taken out of h=. The very first post to the list will have [RndTbl] prepended. Subsequent replies shouldn't have anything prepended, I don't think. Thinking about it a bit, it shouldn't be the end of the world to remove Subject as a checked header. Ya, it's not ideal, but that only leaves the subject for spammers to abuse, still not the body.
I'm 99% positive mailman does not change Date, To, Cc, In-Reply-To (seems absent) and (hopefully) References. Excluding IRT and Refs should likewise not cause any grief.
Would recommend disable the DKIM check in spamassassin on the mailing list or strip DKIM headers before wrapping and relaying the messages to the list. https://wiki.list.org/DEV/DKIM https://wiki.list.org/DEV/DKIM
Like I said, MUUG spamass seems to pass DKIM just fine (on emails from all 3 of us). Your idea about having mailman strip the DKIM headers sounds like the better idea, however, some sites (maybe gmail) are sticklers for DKIM working properly to avoid getting in spamboxes. (Yes, usually one of the methods is enough.)
I can't find a TXT DK record for abrao.net... Mine are all under main._domainkey.*, but is "main" user-selectable? How do the MTAs know which TXT record to retrieve? Is it hidden in the dk header somewhere? I'd like to look at Alberto's DK DNS record to see what's going on there.
Argh. This is why I don't like messing with this stuff :-) I prefer to wait for a fire and then put it out. However, gmail spamblocking Alberto is just such a fire...
And Sean is 100% correct that most of these antispam methods are tough to jive with mailing lists. The creators of these things didn't think through all the use cases. And thus we're stuck with 3-4 different standards, lots of the (non big-tech) players (like me and Alberto) implementing 1 or fewer of them, and tons of real world problems.
