Internet Fax Direct SMTP

Direct SMTP is a feature that allows Internet Fax-compatible devices to send and receive fax data directly to and from each other without going through an email (SMTP) server. Configuring this setting allows faxes you send to be delivered directly to the recipient's Internet Fax-compatible device without going through a server.

Note that Direct SMTP Send and SMTP Receive can each be enabled or disabled individually.
