MFDs must not allow scan to SMTP (email).

The SMTP engines found on the MFDs reviewed when writing the MFD STIG did not have robust enough security features supporting scan to email. Because of the lack of robust security, scan to email will be disabled on MFD devices. Failure to disable this feature could lead to an untraceable and possibly undetectable compromise of sensitive data. The SA will ensure MFDs do not allow scan to SMTP.
