reject mails if domain doesn't pair return path

Hi friends.
I'm using GW2012 on a windows server 2012R2.
Sometimes there is a storm of mails using a provider that is not listening in a spamblock-list and our customers also use this provider.
Therefore mails will pass throu but the return path is different to the sending domain.

i.e.
Return-path: <ekkehardt3jyn2z9@govtjobsmag.com>
Received: from mx3.bon.at ([213.33.87.8])
by mail.cor.at with ESMTP; Tue, 27 Feb 2018 05:55:13 0100
Received: from genera.govtjobsmag.com (genera.digloot.com [212.83.184.210])
by mx3.bon.at (Postfix) with ESMTP id 694D7800E0
for <zentrale@cor.at>; Tue, 27 Feb 2018 05:50:32 0100 (CET)


is there a possibility to check the receiveed-domain with the return-path-domain in GWIA or GW-client and if it doesn't pair, the mail wil be reject?

best regards Rupert

    Groupwise basically does not contain any sort of anti-spam
    functionality, that's a job for third party products specialized on that
    job. Gwava aka now Microfocus Secure Gateway could easily do this.
