Helpful notes

Keep in mind

Older iOS menus

Earlier releases may go directly from Add Account to Other → Add Mail Account. Do not look for the old top-level Mail settings menu on a newer iPhone.

Certificate warning

Stop if the certificate does not match the server. Recheck that the hostname is fusion.mxrouting.net; do not switch to an unencrypted connection.
