Graymail Detection 
and Safe 
Unsubscribing

The Email Security appliance allows you to:

Identify graymail using the integrated graymail engine and apply 
appropriate policy controls.

Provide a secure and easy mechanism for end users to unsubscribe 
from unwanted graymail using cloud-based Unsubscribe Service.

You can monitor detected graymail using the following reports:

Overview page > Incoming Mail Summary

Incoming Mail page > Top Senders by Graymail Messages

Incoming Mail page > Incoming Mail Details

Incoming Mail page > Incoming Mail Details > Sender Profile (drill 
down view)

Internal Users page > Top Users by Graymail 

Internal Users page > User Mail Flow Details

Internal Users page > User Mail Flow Details > Internal User (drill 
down view)

If you have enabled service updates, scanning rules for the graymail 
management solution are automatically retrieved from the Cisco update 
servers.

See the “Managing Graymail” chapter in the user guide.

In AsyncOS 9.5, you cannot configure graymail detection and safe 
unsubscribing using CLI. 

Web Interaction 
Tracking

The web interaction tracking feature provides information about the end users 
who clicked on rewritten (policy or Outbreak Filter) URLs and the action 
associated with each user click.

Once you enable this feature, you can use the Web Interaction Tracking report 
to view information such as top malicious URLs clicked, top users who clicked 
on malicious URLs, and so on.

Web Interaction Tracking report modules are not updated in real-time 
and are refreshed every 30 minutes. Also, after clicking a rewritten 
URL, it may take up to two hours for the Web Interaction Tracking 
report to report this event. 

See the “Protecting Against Malicious or Undesirable URLs” chapter in the 
user guide.
