Change “Use SSL” to OFF

6. In the “Authentication” section set it to “Password”

7. Set the “Server Port” to 587

Note – as mentioned toward the top of this article, when you change these server settings may encounter a “Cannot Verify Server Identity” message, sometimes several times in a row, and you may have to click “Continue” each time to move forward.

Depending on your device, you may need to click a “Done” button now.

8. Go back to the main “Settings” page and then get out of the config all-together.

You should now be able to send email from your device since it is now properly SMTP Authenticating.
