9.17. Direct Internet Fax XMT - Extended Feature
Direct Internet Fax XMT uses Simple Mail Transfer Protocol (SMTP) to transfer mail reliably and efficiently.
An important feature of SMTP is its capability to transport mail across networks, usually referred to as
SMTP mail relay by employing SMTP server.
Direct Internet Fax XMT allows you to transmit documents to another Internet Fax directly without using an
SMTP Server. For this feature to work reliably, configure the IP Address to remain unchanged (static), ask
the Network Administrator to reserve the IP Address. The Subnet Mask and Gateway must be configured
as well. The Domain Name of the machine and other record information must be properly registered on the
DNS Server.
For the Direct Internet Fax XMT to function properly, the DHCP Parameter No. 22 setting must be disabled
in the General Settings (For Key Operator).
Furthermore, in common cases only email and web service from the Internet are permitted into the
corporate intranet, and corporate network administrators are extremely unwilling to open the firewall for
other, incoming services, since each opened path represents additional, potential security threats.
This makes Direct Internet Fax XMT attractive because it can operate throughout the organization's
Intranet.
Several new service extensions were assigned.
(1) The EHLO keyword value associated with this extension is "CONNEG"
(2) A parameter using the keyword "CONNEG" is added to the RCPT-TO command
