Hello mail admin, Currently the nut-upsdev mailing list mail is mostly getting marked as SPAM (or SPOOF) due to failed DKIM.
DKIM is trying to verify mail headers signed by the original sender, but using the mailing list DKIM key (or lack thereof). This occurs because the DKIM mail authentication looks for a authentication key for the headers based on the HELO/ELHO user, but the message is DKIM signed by the original user not the HELO/HELO user (which is [email protected]) so the DKIM authentication of the headers fails. Modern Mailman installations have an option to 'wrap' DKIM signed headers so that DKIM is not misapplied to the mailing list's mail. If you could enable that option it would be really helpful to avoid nut-upsdev mail ending up on the spam folders of most recipients.
