cPanel Self Signed Certificates & Warnings
cPanel uses self-signed SSL certificates by default when you connect to the server for cPanel/WHM/Webmail/Exim/Dovecot/FTP
If you try to connect using a mail program with SSL settings, you will get certificate warnings when you connect to a self signed certificate
You can either:
a) Manually accept the certificate and the mail program should allow you to make a permanent exception so you are not prompted with the warning every time
b) Use non-ssl settings in the mail program
c) Purchase and install a signed SSL certificate for the cPanel servers services (cPanel/WHM/Webmail/Exim/Dovecot/FTP) normally for the servers hostname.
We have SSL certificates available http://www.quexsolutions.com/ssl/
