Fax Communication Features
D255/D256 FAX OPTION 158 SM
the IFAX issues an error to the SMTP server and outputs an error report.
Auth. E-mail RX
In order to limit access to mail delivery with IFAX, the addresses of senders must be limited using
the Access Limit Entry. Only one entry can be registered.
1. Access Limit Entry
For example, to limit access to @IFAX.ricoh.co.jp:
gts@IFAX.ricoh.co.jp Matches and is delivered.
gts@IFAX.abcde.co.jp Does not match and is not delivered.
IFAX@ricoh.co.jp Does not match and is not delivered.
2. Conditions

The length of the Access Limit Entry is limited to 127 characters.

If the Access Limit Entry address and the mail address of the incoming mail do not match,
the incoming mail is discarded and not delivered, and the SMTP server responds with an
error. However, in this case an error report is not output.

If the Access Limit Entry address is not registered, and if the incoming mail specifies a
delivery destination, then the mail is delivered unconditionally.
Handling Mail Reception Errors
Abnormal files
When an error of this type occurs, the machine stops receiving and commands the server to erase
the message. Then the machine prints an error report and sends information about the error by
e-mail to the sender address (specified in the "From" or "Reply-to" field of the message). If there is
an incomplete received message in the machine memory, it will be erased.
The machine prints an error message when it fails to send the receive error notification after a
certain number of attempts.
The following types of files are judged to be abnormal if one or more of the following are detected:
1. Unsupported MIME headers.
Supported types of MIME header
Header Supported Types
Content-Type Multipart/mixed, text/plain, message/rfc822 Image/tiff
Charset US-ASCII, ISO 8859 X. Other types cannot be
handled, and some garbage may appear in the data.
