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

Submitted by sonoracomm on Wed, 01/27/2016 - 15:31 Pro Licensee

Hi,

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 'mail.customerdomain.com'?

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

Thanks in advance,

G

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.
