Topic: DKIM fails on internal emails via Amavis?

Hi everyone, I’m running iRedMail on Ubuntu 22.04 (fresh install about two weeks ago). Outgoing emails to external domains pass DKIM normally, but emails sent between users on the same server sometimes show DKIM fail in the headers. I’ve already checked DNS records, OpenDKIM status, and restarted the related services, but the issue still happens occasionally.

Has anyone experienced DKIM failing only for internal emails like this? Should I check something specific in Amavis, Postfix, or OpenDKIM configuration?

iRedMail doesn't use OpenDKIM at all, did you install it manually after iRedMail installation?
