Go to Settings.
Click on Mail, Contacts, Calendars.

Click Other.

Click Add Mail Account.

The New Account window appears.
Enter your account settings.
Name: Enter your preferred "from" name.
Email: Enter your FULL email address. (i.e. john@domain.com)
Password: Enter your email password.
Description: Enter your preferred account description.

Click Next.

The next screen will open, with IMAP selected as the default.

If you would like to use POP instead, click POP.  

The Name, Email, and Description should be already filled in from the previous screen.

Under Incoming Mail Server:
Host Name: Enter your mail server as listed in your hosting account document. (For most accounts, this will be mail.domain.com. If your hosted domain is "domain.com", your mail server will be "mail.domain.com".)
User Name: Enter your FULL email address. (i.e. john@domain.com)
Password: Enter your email password.

Under Outgoing Mail Server:
Host Name: Enter your mail server as listed in your hosting account document. (For most accounts, this will be mail.domain.com. If your hosted domain is "domain.com", your mail server will be "mail.domain.com".)
User Name: Enter your FULL email address. (i.e. john@domain.com)
Password: Enter your email password.

Click Save.

A window will appear that says "Cannot Verify Server Identity".
The error appears because the security certificate is tied to the common name of the server, and not the specific domain. You can use the server address (i.e. web001.mivamerchant.net, etc) as the Host Name if you want to avoid receiving this one time alert. (You will need to contact us for your site's specific server address.)  This error is normal.

Click Continue.

If you have successfully set up your email, you will see the following screen below:

Click Advanced.

Turn the Use SSL off.

Change the Incoming Server Port to 110.

Please remember that Port 110 is for POP only and if you want to use IMAP, it needs to be set to Port 143. For the outgoing server port (SMTP), you should use 587 (which is the default).

If you are using POP, we suggest changing the Delete from server option to Seven days to allow your non-mobile devices to download their own copy of new email.

Remember to click Test Account and Done when you are finished editing the advanced settings.

Congratulations! You have successfully set up your mail.
