If there is not a more specific E-mail setup how to available, you may use the following information to determine the information you need for setting up your E-mail. The following tables list all of the E-mail server's supported options.
You should pick one option for inbound E-mail, and one option for outbound E-mail. Unless you have a specific reason to choose different options, the recommend setup would be IMAP StartTLS for inbound E-mail, and SMTP StartTLS for outbound E-mail.
