INTERNET MAIL COMMUNICATION
SM 4-7 IFAX
Internet Fax
(IFAX)
Characteristics of POP3/IMAP4 Reception
Here are some general characteristics of POP3/IMAP4 receiving:
• No MX record registration . There is no need to register the machine in the MX
record of the DNS server.
• Power can be switched off . As long as the machine is not receiving mail, mail
stored in the mail server is not lost when the power is switched off. With SMTP
reception, if the machine is switched off, the SMTP server sends an error report
back to the sender, and the machine will not receive the mail unless the sender
sends it again after the machine is switched on.
•
Dial-up compliance . POP3/IMAP4 can be accessed spontaneously, making it
ideal for dial-up operation.
SMTP Reception
SMTP Mail Reception Procedure
By registering the IFAX as an SMTP server in the MX record of the DNS server,
you can enable direct receiving of mail from the SMTP server.
When mail is sent to the mail address specified for the IFAX, it is received
immediately without checking the server for the arrival of new mail (as is done in
the POP/IMAP protocol). Also, with SMTP, the received mail can be routed to
another fax (this is known as ‘delivery’).
Setting Method
The following settings are required for SMTP receiving:
•
The IFAX must be registered as an SMTP server in the MX record of the DNS
server, and the address of the received mail must specify the IFAX.
•
Enable SMTP reception:
User Tools> System Settings> File Transfer> Reception Protocol
Even if the MX record on the DNS server includes the IFAX, mail cannot be
received with SMTP until SMTP reception is enabled:
However, if SMTP reception is selected and the machine is not registered in the
MX record of the DNS server, then either IMAP4 or POP3 is used, depending on
the setting:
User Tools> System Settings> File Transfer> Reception Protocol
