Filters Order of Operations

The Proofpoint Essentials system has been changed in May 2015, the most notable change is the addition of Sender Lists rather than the traditional adding an allow/block to the filters.

The below is a listing of the End-User Sender Lists - Block (SMTP Address) of operations of how our filtering services flow.

Prior to the filters going, messages are pre-scanned for IP reputation, and can get blocked prior to filters blocking these. This should be taken into consideration with creating filters.

 *Notes

  • A Group or Organization filter can be created that over-rides a higher order via the "ignore previous destination."
  • Non-licensed users do not gain the benefits of the filter or sender lists.
