Hi, I am looking into decreasing the amount of spam received. I already followed some great tutorials about implementation of postgrey and rbl services and must say, this helps a lot! However I noted the following, snip from a spam mail I received. (I removed some information, this i have included between <thesebrackets>): Code: X-Spam-Status: No, score=0.8 tagged_above=-9999 required=4.2 tests=[BAYES_50=0.8] autolearn=ham Received: from <myserver> ([<myIp>]) by localhost (<myserver> [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id BipSRhb3IfLu for <884d6bc77@<oneofmydomains>>; Fri, 27 May 2016 12:37:56 +0200 (CEST) Received: from relay0.<myhostingproviderdomain> (relay0.<myhostingproviderdomain> [IPv6:<someipv6address>]) by <myserver> (Postfix) with ESMTPS id 8106430F552 for <884d6bc77@<oneofmydomains>>; Fri, 27 May 2016 12:37:56 +0200 (CEST) Received: from 212.183.200.185.static.user.ono.com (212.183.200.185.static.user.ono.com [212.183.200.185]) by relay0.<myhostingproviderdomain> (Postfix) with ESMTP id 3rGMsw138gz12Nj for <884d6bc77@<oneofmydomains>>; Fri, 27 May 2016 12:37:55 +0200 (CEST) Date: Fri, 27 May 2016 12:37:55 +0200 What happens here is that my hosting provider runs a relay server that I use. Should my own mail server be down for whatever reason, the hosting provider will accept e-mail on my behalf and later forward this to my server using their relay0 server. It seems however that the delivery checks done by Postfix / Amavisd-new / SpamAssassin are done against the relay0 server of my hostingprovider instead of against the original sender. Is there a way I can alter this behaviour for the case where I receive this mail from the relay0server so that it looks at the received header before the relay0 server was involved? I'd normally first Google this type of thing, but I have noooo idea as to what my search term should be for this specific case. Any help would be appreciated! Tnx, Robin
