I recently deployed a secure email server on my server at home and in that process I applied a new SSL certificate to the mail server. I already had a self signed certificate in place for my website, but I'd like to delete that and put the new SSL in place since it's not self signed.
The email server tut I used was arstechnica from last month
So my question is how do I remove the self signed certificate and use the new certificate OR can I even do that?
do I need to generate an additional cert for the website?
When I visit startssl.com and retrieve the certificate, it says it is for mail.mydomain.com (Server - Class 1 - 2015-04-25)
