In Google's Postini service we have a number of domains in our "Blocked Senders" list, messages sent to us from these domains are automatically quarantined as a result.
What we would like to do is just have any messages from the "Blocked Senders" list automatically deleted as they still appear in the daily summary of quarantined messages and are a distraction from genuine emails.
We already know that we don't ever want to read emails from our blocked senders, is there a way we can configure Postini to automatically delete emails from blocked domains either through the "Blocked Senders" list or some other method?
