I'm struggling a little on the best way to setup email authentication for our clients. Email is configured and working, authentication is working w/ the default certificate.
Ideally I'd like to generate a self-signed (or commercial) cert for each client but it looks like I can't do that. Right now our clients use mail.domain.tld for POP/SMTP, is it possible to provide a cert for each domain in this way?
mail.domain1.tld, mail.domain2.tld, mail.domain3.tld, etc.
Thanks for your guidance!
