Going through my mail logs I noticed that a couple of messages from the Dovecot mailing list failed DKIM validation.

For example, this one has failed: https://markmail.org/message/te7tycmpiutw4kia

dovecot.org use mailman-2.1.15 which is "a little bit (~9 years)" behind latest 2.1.34 Older version of mailman are know to modify some messages which break DKIM.

That may be the reason for your observation.

BTW: the ARC-Seal added by dovecot.org is invalid here, too

Can you give any more insight on why it's invalid? Last time I checked the ARC-Seal was fine.
