Hi, I'm basically trying to protect my users from the following:
Spam - Sent from accounts hosted on freemail providers (yahoo, ...) - Originating from AfriNIC ranges - Tergetted at several dozen of users The headers look like this: Received: from [41.207.213.162] by web1104.biz.mail.sk1.yahoo.com via HTTP; Tue, 04 May 2010 14:44:20 PDT It is fairly trivial to block suck things via a header access map if /^(Received|X-((Origin(ating)?|Client|MDRemote|Sender)-?IP|(Client|Remote_)Addr|PHP-Script)):/ /\b(41\.\d+\.\d+\.\d+)\b/ REJECT regional junk 001 #Africa endif Some of my users receive a few legitimate emails from Africa. Apart from using a policy server, can postfix natively be configured to acheive this goal ? Since header access do apply to all emails, I don't think so, but ... it's worth asking ;) Thanks Laurent -- lca...@unix-scripts.info
