Internet Communication Features
22
Simple Mail Transfer Protocol (SMTP) is used 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 SMTP allows you to transmit documents to another Internet Fax directly without using an SMTP
server. For this feature to work reliably, the IP Address should remain unchanged (ask your Network
Administrator to reserve the IP Address). The Domain Name of the machines and other record information
must be properly registered in the DNS server.
Further more, 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 SMTP attractive because it can operate throughout the organization's Intranet.
Capability exchanges and content negotiations are also available to take advantageous communication
between Internet Fax communications.
