My VPS has no need for https, but I would like to use Secure SSL Email. The cPanel setting for incoming and outgoing servers would be host.mydomain.com. It was recommended I purchase a wildcard cert for mydomain.com and host.mydomain.com ... which I did. Now I'm told that a single cert on host.mydomain.com would have been adequate. Since cert renewal is coming up, I'm wondering if I could save a bundle of money by getting a single domain cert for just host.mydomain.com. What's right - Single or wildcard cert?
