Client (Virtual Server) SSL Certs with SMTPS/POPS/IMAPS


I am not sure, but I thought I read someplace that customer SSL certificates could also be used for POP/IMAP/SMTP. Is that true?

Is it possible for a customer virtual server with its own IP address and SSL certificate to have that cert presented by Postfix/Dovecot when, for example, a mail client accesses the mail server at ''?

I'm just trying to avoid dealing with mail client SSL certificate warnings.

Thanks in advance,


p.s. The domain I'm working on right now has a wildcard cert.



That's correct, if you have a Virtual Server on it's own private IP address, then adding a new SSL certificate to that Virtual Server should copy in that SSL certificate into both Postfix and Dovecot.

That only works on a private IP address though -- you can have one per IP address.
