Dear all,

i set up my DKIM key as a catchall key, as described here https://docs.iredmail.org/sign.dkim.sig … il-domainsand so far it works and doing a check with amavisd-new and external dkim-check-website is fine for my "primary domain". I now reveived this error for one of my other domain on this server:

550,"5.7. 1", The message was quarantined because of Domain Keys
Identified Mail (DKIM) violation ->
The domain that you are sending to has a policy in place that prevents
your message from being sent.
DKIM: permfail - signature mismatch.

Does anybody know howto check the other domains on my server against the catchall DKIM key?

Do i have to add the catchall DKIM key for each domain in the DNS?

Thanks in advance

What specific steps can be taken to check a catchall DKIM key for all mail domains on an iRedMail server, particularly regarding DKIM signature mismatches for multiple domains?
