Before Connecting the Machine to Internet
Before connecting to the network, read this section to understand the Internet Fax
functions.

POP and SMTP

The available functions depend on whether this machine is setup to use the POP or
SMTP for retrieving E-mail from a mail server.
POP (Post Office Protocol) and SMTP (Simple Mail Transfer Protocol):
“SMTP” is a server protocol for sending E-mail messages between servers.
Usually the E-mail systems that transfer E-mails over the Internet use SMTP to
send messages from one server to another. Then the E-mail message can be
retrieved with an E-mail client using either “POP” or “IMAP”. “POP” is a protocol
used to retrieve E-mail from a mail server.
When this machine uses POP for the Receive Mode:
This machine works as a POP client. Similar to most e-mail applications, this
machine uses POP for receiving an E-mail message and SMTP for sending an
E-mail message.
When this machine uses SMTP for the Receive Mode:
This machine works as one of the mail servers. The machine can transfer an E-
mail message in the SMTP transmission.
The following table shows the available functions according to the type of the
protocols set for the Receive Mode.
If the use of the Offramp Gateway function is not necessary, it is recommended
that the Receive Mode is set to “POP” because some settings will be required to be
set on the mail server if the Receive Mode is set to “SMTP”. For more information
about the Offramp Gateway function, see “OFFRAMP GATEWAY SETUP” on page
85.

Precaution for Internet Transmission

Transmissions using the Internet Fax function are the same as E-mail transmissions.
Before you start to use the Internet Fax function, it is recommended that you read this
section and understand the precautions for Internet Transmission.
• The Internet Fax sends a document to the email server of Internet and it does not
send via the PSTN alike regular facsimile transmissions.
• An error mail is sent back from the mail server when the E-mail document fails to
be forwarded to the recipient.
• An error mail is sometimes not sent back even if the E-mail has failed.
• Internet transmission has low security. It is recommended that you use regular
facsimile transmission when a contidential document is sent.
• It may take a considerable amount of time for the recipient to receive the document
because of the line traffic in the Internet.
• If the document being transmitted has a large amount of data it may not be
successfully sent due to the configuration of the E-mail Server.
