We are having an excessive amount of spam messages hit our mail server (SmarterMail 5.1) over the past week or so (nothing new there), however they are never being routed to SpamAssassin since the sender's email address is the same as the receipt's address. To clarify this point, here is the header from one of the spam messages: Return-Path: <firstname.lastname@example.org> Received: from 42-125.127-70.tampabay.res.rr.com [18.104.22.168] by rcs02.xyzmanuf.local with SMTP; Thu, 11 Dec 2008 14:37:05 -0600 To: <email@example.com> Subject: Re: Order status From: <firstname.lastname@example.org> MIME-Version: 1.0 Content-Type: text/html X-SmarterMail-Spam: SPF_None X-SmarterMail-TotalSpamWeight: 0 (Intra-Domain) You can see the message clearly comes from an external source, however the spam weight given to the message is zero since SmarterMail thinks the message is an internal message. The messages are really getting annoying and he who holds the purse strings wants it to stop. Unfortunately I am up against a wall here. Does anyone have any recommendations (outside of the obvious additional software/hardware) on how I can get this to stop with the SmarterMail app. I already have installed? Thanks for the help!
