Add your incoming mail settings. This will be your full email address, your username which is also your full email address, and your password. Your imap or pop server would be mail.domain.tld, replacing domain.tld with the customers actual domain. Security would be none and port should stay at the default.

Your outgoing settings will be essentially the same as your incoming settings. Make sure you click "login required" on the top "security type" can stay as "none" and port should be changed to 1025.

Keep in mind that andoid has more mail programs than we care to count. If the customer is looking for a good example or is having difficulties with the default mail program we've noticed K9 mail seems to have fewer problems. These steps can be followed, generally, to set up all of them

If you get stuck remember the options button, not shown on most screenshots, will get you started.
