Changed host server name, DKIM still shows the old name

Virtualmin
1
SYSTEM INFORMATION
OS type and version RHEL 9
Usermin version 2.400
Virtualmin version 7.40.1

I changed the IP and FQDN for the host server of Virtualmin.

All good but I noticed today that going:
DNS Settings → DNS DKIM Record, still has the old FQDN.

How to update that to the new FQDN?

Not 100% on this but i think you go to virtualmin / email settings / domainkeys identified mail/
Should be able to set the new hostname and sign keys etc for it in there for every domain that uses them.

Update your DNS with the new DKIM record, remove the old one, make sure the selector matches your new server, let DNS propagate, then restart your mail service.

4

Turn off dkim and then re-enable

And/or run check virtualmin config

Nothing helped so far, including re-running the Wizard.

Waiting for EL10 to be classified as Class-A so I can build a new server from scratch.
