The fun thing is that exactly *now* there is a thread on the bug-bash mailing-list almost about exactly that. And i (not subscribed, but reading that via gmane) responded to Robert Elz (kre@!) || The debug headers indicate an "Invalid DKIM signature" which appears || to be causing the posts to be flagged. | |That's because the From header is being changed by the list to work |around some other "spam protection" mechanism that lots of people seem However, dear Robert, since DKIM prefers looking at a signature which matches the domain present in the first address of From:, only that is the right thing to do if you do change the message. The NetBSD lists have chosen not to change messages, so that the original DKIM signature still verifies, which is the other approach. (I however do not like it since i love those [TAG] things, and it all would be no problem for user interfaces *if only* the MUAs would start using RFC 9057 Author: as "the real thing" in From: (not to talk about Sender:), if present.) Btw, only to mention it, me asking in [rt5.ietf.org #38946] on this anti-social slashing of the RFC5322.From's signature and all that, got as response from "Robert Sparks via RT" We are aware of these things and will keep them in mind as the mail system evolves. which is totally funny given that i appear as myself in From: in messages to ietf-dkim@.
