I have an active SSL cert for "domain.com" that is hosted on Server1. If I have a mail service that is hosted on Server2 and uses the same domain root, "@domain.com", would I be able to use the same cert? Or do I need to buy a second SSL for the same domain on the mail server?
CodePudding user response:
- Your certificate's SAN (Subject Alternative Name) should either contain both of the target domains or a wildcard domain like
*.domain.com
. - Additionally, the private key must be copied from server 1 to server 2.
If you follow the suggestions above, you should be good to go.
