Message-ID: Hi all, I've had a question/issue raised with DKIM on the TUHS/COFF mailing lists from a subscriber. I'm running Mailman3 and I'm a DKIM newbie. They say: Why have all mails from the tuhs mailing list, except those from a real tuhs.org domain (basically only yours), an invalid DKIM? Background, my mail provider will switch its DMARC policy from "none" to "quarantine" and then to "reject" - which will result first in tuhs-mails being marked as "spam" and later being rejected. Other mailing lists I receive, switch the sender domain to the list domain itself. This results in a correct DKIM. Wouldn't this be possible for the tuhs-list too? He gives, as examples: Maillist mails from senders "via TUHS " pass DMARC (e.g. Cameron Míċeál Tyre via TUHS ). Maillist mails from senders without the "via TUHS" part fail DMARC (e.g. Blake McBride ). I'd be very happy to have someone/some people review my mailman3, postfix and rspamd configuration and suggest changes. Many thanks in advance, Warren P.S.

Didn't you provide dedicated DMARC/non-DMARC lists in the past? Ah. I have no idea on rspamd, and do not get me started on the IETF email scene, they are really, really no good people. But. Mailman3 config is at [1] - Remove (or rename) old DKIM headers [1]: not so important, but good. Because. remove_dkim_headers: yes Since TUHS/COFF luckily still tags the Subject: line, which i personally like very much, any old signature is broken. So they need to be removed since DKIM gives verifiers practically free hands what is to be tested. Now DKIM says it is sufficient if *one* signature can be verified. But leaving in false ones may cause unnecessary traffic, and maybe even these rubbish Authentication-Results stuff. (They represent a snapshot in time and space, which may be wrong in the second after they are generated.) - Perform the mitigations [2]. Ensure to *always* mitigate and change the From: line to those "via" style things. dmarc_mitigate_unconditionally dmarc_mitigate_action: munge_from [1] https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/config/docs/config.html [2] https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/handlers/docs/dmarc-mitigations.html In general it can only be "mitigate, mitigate, mitigate" (think Ballmers "Developers! Developers! Developers! -- just like that!), and unconditionally so, because why have all the DNS lookups and all the noise for nothing, just give anyone the same appearance. And. Even if those IETF email well people push through the wrong standard, the next DKIM will allow user interfaces to unroll changes to the IMF (internet message format aka RFC 5322 aka email message), and therefore *user interfaces* can undo the From: mitigation, and show the original From:, and therefore all the people who hate that "x via y" syntax will later have the possibility to do something about that for themselves (shall their MUA allow so), whereas on the actual SMTP etc level things (only partially, alas!!) get more straight again. Having said all that i have no Mailman3, i still run Mailman2, but the above is at least what [1] and [2] says, and the direction is the right one. ;) |Many thanks in advance, | Warren | |P.S.

Hmm. Indeed, dear Warren, whereas your message had a DKIM signature (even two), this one of mine that was returned via COFF does not have any DKIM signature in it at all? I think Mailman3 can do anything on its own, the question is how you do it, via it, via external milters (rspam), and how it all interacts :-) Email is too complicated, but you will not move them a bit, it is very, very sad. All this could however also be PEBKAC ("Problem Exists Between Keyboard and Chair") from my side. But the above are anyway the correct suggestions. How to do it with Mailman3, with that terrible documentation? Maybe https://docs.mailman3.org/projects/mailman/en/latest/_sources/src/mailman/rules/docs/dmarc-mitigation.rst.txt helps you a little bit more. --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt) From coff at tuhs.org Fri Aug 22 08:52:46 2025 From: coff at tuhs.org (Warren Toomey via COFF) Date: Fri, 22 Aug 2025 08:52:46 +1000 Subject: [COFF] OT: Any DKIM People Out There?
