Share Website certificate with SSL/STL Dovecot IMAP and Postifix SMTP

[Sean Kamath]

In a word, yes.

I use the same cert for Dovecot and Sendmail.  I don’t bother with HTTP, but it would work just fine.

Certs are basically certs — you can use the same one in multiple places.

As for keeping it from things being seen as spam. . . I’m not sure how that would work.
