Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

If the end users in your organization have configured Safelist for their own email accounts, graymail 
messages from a sender in the safelist will not be scanned by the graymail scanning engine. For more 
information about Safelists, see 

The graymail detection and safe unsubscribing information is posted to the following logs:

Graymail Engine Logs. Contains information about the graymail engine, status, configuration, and 
so on. Most information is at Info or Debug level.

Graymail Archive. Contains archived messages (the messages that are scanned and associated with 
the “archive message” action). The format is an mbox-format log file.

Mail Logs. Contains information about graymail detection and addition of banner for safe 
unsubscribing. Most information is at Info or Debug level.

After clicking on the Unsubscribe link, the end user sees the following message: “Unable to 

unsubscribe from…”

This problem can occur if the Unsubscribe Service is unable to perform the safe unsubscribe on 

behalf of the end user. The following are some of the common scenarios in which the Unsubscribe 
Service is unable to perform the safe unsubscribe:

Unsubscribe URI or 

mailto

 address is wrong.

Websites that require the end users’ credentials to unsubscribe.

Websites that require the end users to confirm the request of unsubscribing by logging into their 
email accounts.

Websites that require captcha to be solved and the Unsubscribe Service is unable to solve the 
captcha.

Websites that require interactive unsubscribing.

The end users can use the URL provided at the bottom of the unsubscribe page to unsubscribe manually.
