Danil --
I've learned something today. I did not know you could check the authentication.
When I check a message that I received from the list I am told: ARC-Authentication-Results: i=2; mx.google.com; dkim=neutral (body hash did not verify) header.i=@bellsouth.net header.s=s2048 header.b=nkq1aBRe; arc=pass (i=1); spf=pass (...
I also see this: ARC-Authentication-Results: i=1; pb-mx22.pobox.com; arc=none (no signatures found); bimi=skipped (DMARC did not pass); dkim=fail (message has been altered, 2048-bit rsa key sha256) header.d=bellsouth.net header.i=@bellsouth.net header.b=nkq1aBRe header.a=rsa-sha256 header.s=s2048 x-bits=2048; dmarc=none policy.published-domain-policy=none
How do I fix this DKIM error? Has the body changed because I add a footer to emails as they pass through?
Note that bellsouth.net is the original sender's email domain.

Hi Steve,
Have you checked "Show original" page in Gmail for the messages coming from the list? Does it have SPF, DKIM, and DMARC checks all "PASS"?
Have you checked if your mailing list server IP hasn't been caught by some anti-spam blacklist?
I wouldn't consider the Promotions folder as the issue at all... It is not a punishment, just an imprecise classification caused by the message content most probably.
With my best regards, Danil Smirnov Mailman3.com

I run a number of small lists for my neighborhood association. The largest of these is ~120 users. Typical volumes are about 2 messages/day.
In the past week or so a number of users who use gmail as their email client have complained that list emails have been going to spam or "promotions" folders. I've always had 1 or 2 users who had trouble receiving mails, but this seems to be a significant percentage of all gmail users.
I have DMARC mitigation set to unconditional, and the DMARC action set to "Replace From: with list address".
My emails are sent using google workspace as my SMTP relay.
I'm trying to teach my users to whitelist the list domain, but they are not, in general, a tech-savvy bunch, so it is slow going.
Anyone else suddenly having trouble with gmail? Any suggestions?
Thanks!!
