Use the Action tab on the Sender ID properties to configure Sender ID to take one of the following actions when Sender ID determines that a message is spoofed or when a transient error is returned.

Reject message

To reject the message and send a Simple Mail Transfer Protocol (SMTP) error response to the sending server, select Reject message. The SMTP error response is a 5xx level protocol response with text that corresponds to the Sender ID status.

Delete message

To delete the message without informing the sending server of the deletion, select Delete message. The Edge Transport server sends a fake "OK" SMTP command to the sending server and then deletes the message.

Stamp message with Sender ID result and continue processing

To stamp the message with the Sender ID status, select this option. This metadata is evaluated by the Content Filter agent when a spam confidence level (SCL) is calculated. This setting is the default option for Sender ID properties.
