We are using postfix with debian lenny...
We are receiving what appears to be backscatter from spam that is using a
valid address in the Return Path. I have included an example of the header
info from one of the spam messages below. The “From” and “To” addresses just
seem to be random and are not related to us in any way. Does anyone know to
block this sort of backscatter?
Original message headers:
Return-Path: <soa@* <s...@newmedia.net.nz>*[ourdomain.actual.domain]**>
Received: from 195-191-72-102.optolan.net.ua (unknown [195.191.72.102])
