Sending Internet Fax/E-Mail That Bypasses the SMTP Server

Normally, Internet Fax/e-mail is sent through the SMTP server. With this feature however, the domain part of the destination's e-mail address is read as the SMTP server's address and transmissions bypass the SMTP server. Since this reduces the load on the server, you can send Internet Faxes/e-mails without having to take into account the transfer time from server to destination.

To use this function, the other party's fax machine, computer, or server must:

Methods for specifying a destination to send documents bypassing the SMTP server

There are two methods: specifying the other party's host name or specifying the other party's IP address.

If the host name of the other party is registered on the DNS server, you can specify the host name of the other party as a destination. If it's not registered, specify the IP address (not the host name).

To send a document over an IPv6 network, you must specify the other party's host name (not IP address) as a destination.

  • Specifying the other party's host name

    Specify the address after the @ as follows: "host name", ". (dot)", and "domain name".

    xxxx@host name of the other party.domain name

    For example, if the other party's e-mail address is "abc@defcompany.com" and the host name is "HOST", specify as follows:

    abc@HOST.defcompany.com

  • Specifying the other party's IP address

    Replace the domain part of the e-mail address with the other party's IP address.

    xxxx@[the other party's IP address]

    For example, if the other party's e-mail address is "abc@defcompany.com" and the IP address is "192.168.1.10", specify as follows:

    abc@[192.168.1.10]

If you use the Address Book to specify a destination, the SMTP server settings configured for each destination in the Address Book are applied.

Use this procedure to specify the SMTP server settings manually when you enter a destination directly.

Note

  • To use this function, the port number of "SMTP Server" must be set to "25".

  • SMTP authentication set on the other party's computer or server is disabled when an Internet Fax or e-mail is sent using this function.

  • If an Internet Fax or e-mail is sent from the other party using this function, an error mail notification is not sent to the sender even if reception fails.

  • When an Internet Fax or e-mail is sent using this function, the server does not send an error notification e-mail even if transmission fails.
