Why are users not receiving notification emails with Spam Quarantine Summary?
The Spam Quarantine is user-based. Symantec Mail Security for SMTP 5 is not sending notification emails containing the Spam Quarantine Summary to the users.
The host to which the notification emails are sent does not receive the emails. This may be because the host can't be found, because the host is not capable of relaying these emails, or because the Quarantine is configured for Administrator Only Quarantine.
To confirm that Quarantine is not set to Administrator Only
To check the Control Center settings
By default, a notification process runs every day and determines if users have new spam messages in Spam Quarantine since the last time the notification process checked.
If so, it sends a message to users who have new spam to remind them to check their spam messages in Spam Quarantine.
You can also choose to send notification digests to users on distribution lists.
The administration guide tells you how to do this.
