Allow emails only with authorized addresses or domains

Jay

Can we restrict Incoming emails to specific or contact book of emails only? Any GUI client for this features in pkgsrc ?

Jay fdm should be able to do that. No GUI that I'm aware of, though...

If you run your own server (e.g. postfix) you can restrict allowed addresses to a specific whitelist only
