A SSL Certificate is only a means of verifying the user of that certificate as being who they say they are. The error message you receive when setting up SSL Email is for reason that we do not have an outside authority saying who we are, but you know us, so this is not important.


There are differences in SSL certificates. Self-signed as we are using, is not appropriate for an online sales website, it does not prove to a new client that we can receive their personal data and be trusted to conduct business with it.  For this, you would use either a “Quick SSL, True Business SSL or EV Business SSL”


Quick SSLs are issued by automation, a computer checks certain factors online to verify your domain's online reputation. For a client, there is a lock in the address bar and a cert of authority but not verified. These are cheap but hold less value than a true business.


True Business SSLs are more costly and include an on hands approach in verifying a companies true identity. Like a Quick SSL, there is a lock in the corner of the address bar but if someone wishes to click and read your reputation, it will show that your company has truly been verified.


EV True Business SSL, what most banks use now, is only slightly higher in cost than a True Business (use to be much higher in the past, near double) but provides a massive difference over True Business Certificates. EV or Extended Verification causes the address bar of your clients browser to turn green. This green is like a green signal light, let's buy for the shopper. With the EV green bar, the client does not need to know how to read your companies profile like with a True Business SSL.
