Disable Unused SMTP Services

说明

Simple Mail Transport Protocol, (SMTP) is a protocol designed to transfer mail reliably and efficiently. Some MFDs accept inbound SMTP requests in support of SMTP-to-fax services. It is recommended that this access mechanism be disabled if unused. The use of this protocol may create exposures to threats against the confidentiality and integrity of print jobs. Given this, it is recommended that SMTP services be disabled. Additionally, it may be possible for a malicious entity to abuse MFD SMTP services for nefarious purposes, such as sending unsolicited email. SMTP over TLS/SSL will mitigate passive and casual attacks against the confidentiality and integrity of print jobs while in transit over SMTP. The use of SMTP over TLS is recommended in place of SMTP as it mitigates the confidentiality and integrity threats that affect SMTP.
