Hi,
It seems like the list system is breaking DKIM - triggering bounces, resulting in unsuscribes.
Is there recommendations on how to deal with this?
Looks like it relates 100% to the addition of the footer:
dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-leave@dovecot.org
Kind regards, Jaco

It's using ARC-Signing, but ofc no one supports that. DMARC/DKIM and mailing lists are super fun.
