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.
