Symptom:

When trying to release any quarantined emails from the "quarantine" section at the web management, nothing happening and you are getting "Failed to release" alert.

Cause:

The quarantine service uses its own SMTP configuration to send reports and send the released emails, he is not using the SMTP configuration releated to the Mail Agent.

 

Solution:

To configure the SMTP configuration to the quarantine service that will give you the ability to release emails, you will need to open the web management console> Quarantine>Configure Quarantine Reports.

Under "SMTP Configuration Settings" section press "Update" and add your internal SMTP configuration and then press "SAVE".


Now try again to release an email from the quarantine.
