I am working on a demo that allows each incoming user to provide their domains, and implements DKIM signing for the domains on the fly.

I know one can sign DKIM for new domains with the instructions here:
https://docs.iredmail.org/sign.dkim.sig … omain.html

However, I'd like to know if there is a solution without having to restart Amavisd, since restarting Amavisd each time a user signs up doesn't sound like a great idea.

Maybe update the settings in the DB so that postfix picks it up each time it sends an email?

Thank you.
