Blacklist Behaviour

Namesonic

New Pleskian
Plesk 11.5

We are utilizing the Plesk Blacklist email feature but find that the blacklist applies to only the Return-Path: header if specified and not the From: or Sender: fields.

Most customers do not inspect headers and enter only the From: address as the blacklist value. As a result, the customer continues to receive spam from the same address but coming from different Return-Paths.

Can you verify that the blacklist is ONLY supposed to check the Return-Path field when rejecting email? Or should it also be checking the other available fields?

Thanks in advance.
