Should PEM delete messages from the queue when the user selects to delete them?

We are running Email Security v7.3.

Our users are doing a good job of reviewing their blocked messages and deleting them from PEM.  We have noticed that even though the user deletes the messages from PEM, it remains in the queue until it times out (7 days in our case).  Shouldn't it be removed from the queue as well?   If the messages stay in the queue, it gets very large.

Is this functioning correctly?

Thanks,

James
