Check or Attack Name: smtpdebug

Sendmail was found in debug mode. Debug mode allows an attacker to gain access to a machine through the sendmail port. This option looks for old versions of sendmail that allow debug mode and could provide an attacker access to the machine.

Obtain and install a more recent version of Sendmail, which does not implement the DEBUG feature.
