These instructions are intended specifically for setting up a new email account on Mac Mail under OS X 10.11.1 (El Capitan).

For help with general email account settings, see How To Set up Any Email Client.
Step #1: Create the Account
Launch Mail by clicking on its icon in the dock. Under the Mail menu, select Add Account.
On the Choose a Mail account provider screen, select the radio button next to Other Mail Account and click the Continue button.
On the Add a Mail Account screen, enter your name, the email address and the email account’s password.
Step #2: Account Settings
At this point, you should see an additional popup window with a place for you to add additional settings.
You will need to ensure that all the fields are completed:
Email Address is the full email address you’re setting up.
User Name also is the full email address.
Password is the email account’s password.
Account Type will be IMAP or POP, depending on your preference. For its ability to keep email in sync across multiple devices (desktop, laptop, phones and tablets), IMAP generally is recommended.
Incoming and Outgoing Mail Server
If you are using non-SSL settings, both the Incoming Mail Server and Outgoing Mail Server will be your domain name: mail.yourdomainname.com (or simply yourdomainname.com).
If you are using SSL settings, both the Incoming Mail Server and Outgoing Mail Server will need to be set to the server’s hostname (e.g., host.yourdomainname.com).
Step #3: Security Settings
If you set up the email account with standard connection settings (mail.yourdomainname.com), or you set up the account with secure SSL settings and have an SSL certificate installed on your mailserver, you can skip this section and proceed to Step 4. However, if you’re using SSL settings (host.yourdomainname.com) and your server has a self-signed (free) SSL certificate installed on the mail server, you should see a popup notification about the server certificate:
If you receive this notification, you will need to click either the Continue button to accept the certificate and proceed, or the Show Certificate button to inspect it. Should you wish to permanently store the certificate and add it to the Keychain, you can check the Always trust box before selecting Continue. Depending on your security settings, choosing to permanently store the certificate could require you to enter your password to add it to the Keychain.
Note: A self-signed certificate uses the same level of encryption as a verified certificate, except that it is you who are verifying your server’s identity, rather than a third party. However, if you would prefer to use a third-party verified SSL certificate to cover core services (cPanel/WHM, POP3, IMAP, SMTP and FTP) on your server, you can find instructions for ordering and installing an SSL certificate at Install an SSL certificate on a Domain using cPanel, and you’ll find a guide to installing your certificate on email and other core server services at Installing Service SSLs in cPanel. Should you find that you need any assistance, please feel free to contact a Heroic Support® technician who can assist with obtaining and installing an SSL from the vendor of your choice.
Step #4: Finishing Up
Ensure that the box next to Mail is checked and then click on Done to complete the setup.
You’re now ready to begin using your email account with Mail.
