In order to get a quick overview of outgoing messages blocked by the filter, you can use the report function in the web interface. To do this, go to "Outgoing reports" in the left menu under "Outgoing". Specify one of the predefined periods and the desired classification.
Please note: If you submit your messages via a single user on our outgoing filter (e.g. with a smarthost solution), it is recommended to display the classification "Identity".
