  3. This is in the middle of the page. You should see the number of accounts linked to your phone on the right side.

    • It is worthwhile to learn the SMTP port, as well, since some internet service providers may block the default one.
  9. This is in the top-right corner. Your settings will be saved, and your new SMTP server will be added to your email account.
