• As explained above, the email forwarding feature sends data from the MFP to external destinations
via the network. By changing the network traffic-related settings, which can only be performed by
Network Administrators, it is possible to prohibit or limit the conditions under which emails from the
MFP are actually forwarded to their destinations.
Data Stored in the Job Log
• An entry is added to the job log for each individual job performed, and contains information on the
job settings (e.g. scanning settings, destinations), completion status (whether completed
successfully or not) and user identification (in cases where User Authentication was enabled). The
information is sent to the HDD via the LCS. For more details on job and access logs, please refer to
Job/Access Logs.
Terminology
SMTP (Simple Mail Transfer Protocol) [RFC2822]: A protocol used for the transmission of email over the
Internet.
SMTP-AUTH (SMTP AUTHentication) [RFC2554]: The protocol used for authentication when connecting
to an SMTP server.
POP3 [RFC1939]: An email transfer protocol used when receiving email.
POP Before SMTP: An authentication mechanism using POP3 protocol, developed to guard against
SPAM mail (email sent indiscriminately to a large number of destinations).
SASL (Simple Authentication and Security Layer) [RFC2222]: A framework that provides a common
authentication processing mechanism for protocols that may require authentication, such as SMTP,
POP3 and LDAP.
CRAM-MD5 [RFC2195]: A message digest functional algorithm that uses the MD5 algorithm to encrypt the
challenge string and password.
DIGEST-MD5 [RFC2831]: A message digest functional algorithm developed as a countermeasure to
dictionary and brute-force attacks. DIGEST-MD5 also supports realm designation (FQDN).
LDAP (Lightweight Directory Access Protocol) [RFC1777], [RFC2251]: A protocol used for accessing
directory services that manage items such as user address books.
SMB (Server Message Block): A protocol used to enable file sharing between Windows PCs.
Note: The Ricoh MFP(s) to which this document applies support NTLM v1.
FTP (File Transfer Protocol): A protocol used when transferring files over a TCP/IP network.
