SMTP: TURN Command
This protocol anomaly triggers when it detects an attempt to use the TURN command that exchanges the roles of the e-mail client and server. You might want to ban this command and drop the connection, or edit the SMTP attack objects and change their direction to "BOTH."
Extended Description
Receiving an SMTP TURN command may indicate a configuration error, or a non-standard SMTP implementation. It may also indicate an attack attempt.
