Typical Example - Ricoh IM C300 Service Manual

Explanation
This is an SMTP authentication issue that aborts transmission of an already started Scan to
Email. Currently this has only been reproduced using MS-Exchange server.
MS-Exchange requires that all of the following match:
1. The sender's address in the "MAIL FROM" field. This is also known as the "envelope
sender" or "MIME sender". It is an SMTP command sent at the beginning of the email
transmission process.
2. The sender's address in the mail header "From:" field. This appears as "From" in email
clients. It is a part of the email itself.
3. The email address corresponding to the SMTP username used to login into the SMTP
server.
When the MFP logins into the SMTP server, the email address of the username 3) will be
compared to 1) and 2). If these comparisons fail, authentication will also fail. Exchange server
will stop the transmission procedure, and the "Transmission has failed" message will be
returned to the sender.

Typical example

NG case:
SP5-860-022 is Off:
1. The "MAIL FROM" field = device
2. The mail header "From:" field = use
3. The SMTP username = device
When the SMTP server compares 2) and 3) the Exchange Server will stop the transmission
procedure.
OK case:
SP5-860 can be used to make the values in the above example, match.
In this example, if SP5-860-022 is On, the user's email address in the mail header '2)' will be
replaced by the Administrator's email address.
To solve the problem, the Administrator's address must be the same as the device's address.
If this is done:
1. The "Mail From: field = device
2. The mail header "From:" field = administrator
3. The SMTP username = device
1,2 and 3 must match and the authentication should be successful.
•
The user's email address will still be inserted into the reply-to field.
The device SMTP user name, password, and email address are configurable in [User Tools] >
[Machine Features] > [System Settings] > [File Transfer] > [SMTP Authentication].
User email addresses are configurable in the user configuration of the Address Book.
