How do I install an SSL Certificate into cPanel?
SSL encryption for email is highly recommended whenever possible. Configuring your server/mail client with an SSL will help avoid mail delivery exploits and secure email login attempts. The following article will guide you on how you can install an SSL on your server for email.
It's also important to remember that SSL for email is user-based. Therefore, after the SSL Certificate is installed on your email server, you will want to update your mail clients to the appropriate SSL mail server and port numbers.
Instructions
Grid servers actually come with an SSL already installed on their mail server! To utilize your mail server's SSL, open your email client, set the incoming/outgoing server to your email access domain (xxxx-xxxx.accessdomain.com), and set the appropriate SSL port numbers:
IMAP (SSL): 993
POP (SSL): 995
SMTP (SSL): 465

Resources Before Starting
This guide will primarily assume you are using a Media Temple SSL for email encryption. You will want to ensure that your SSL has the appropriate primary / alternate domain name, such as:
Throughout this guide, we will be using example.com as a placeholder name. When following the instructions, be sure to replace example.com with your ACTUAL domain name.
Can I use a Standard SSL to secure email? It is technically possible to use a Standard SSL with the primary domain name (mail.example.com). However, we recommend using either a Multi-Domain or WIldcard SSL, as that will give you the option to secure mail.example.com, along with other domain/subdomains.
If you wish to use a third-party SSL for email encryption, you may refer to the guide

For cPanel, there typically should not be additional steps required for your install. However, if you wish to check your server to be certain the install was successful, you can do so by logging into the cPanel account for your domain. The following screenshots are taken from a server using the cPanel theme (paper_lantern).
