Sv: dovecot mailing list (this mailing list), DKIM, SPF and DMARC

[Sebastian Nielsen]

I get it too. These appear because they don't replace either MAIL FROM: or Mime From: with the list address. This causes validations to fail since the mailing list is trying to spoof mail in your name, and of course, anti-spoofing security is going to react. DKIM can be troublesome since mailing lists sometimes change or reencode content so DKIM signature fails.

  My domain (serebrtyajov.spb.ru) has all these "new" e-mail technologies configured. It works fine till I write to this mailing list.

  After that I've got several DMARC reports about "spam" from my domain. All these reports are about my mailing list post.

  I don't have such problems with other mailing lists (FreeBSD ones, OpenJDK ones, and others).

  Looks like mailing list software for this mailing list is misconfigured.

  I'm sure, I'll get new after this message.
