The reason code "ase-aoarm" describes a specific white listing having taken place. In short, when a recipient has answered the sender on a previously received incoming mail the sender is automatically white listed. In the priority of rules this white listing is placed directly behind the user / customer created white lists. Thereby awarding it a relatively high priority. 


Should the user now wish to stop receiving emails from this sender, they must create a user based blacklist for this sender.
