You could add the IP addresses of the COX SMTP servers to your Trusted IP Address list, this will bypass ALL AntiSpam filters.

I would like to use the HELO/ELHO COMMANDS for Spam filtering. The problem is, only 1 Legit Mail server has an issue with it. Unfortunately, it is Cox Enterprises, which send about 25% of the email that comes in here. They are like the 10th biggest Privately owned Company in America, owning most of Cox Cable, Cox Television, Rehser Entertainment, Cox Radio, Manheim Auto Auctions; Newspapers all over America, The Women's Soccer League, Direct Mail (snail mail) businesses etc. I could care less about Cox. net which is the mail users of Cox cable. Anyway, all their mail comes through the central server as: Received: from BATL0S04.cbi.cox.com [67.97.216.253] by mydomain.com with ESMTP (SMTPD32-8.02) id A70E3B0248; Thu, 04 Sep 2003 19:13:18 -0400 Received: by BATL0S04 with Internet Mail Service (5.5.2653.19) The issue is their MIS people do not care about Spam and let everything pass (many executives have had it with the Spam and I know several are investigating moving divisions ton outside sources to control it, so this might be end up being their undoing as well in the MIS Department, but that's not going to happen tomorrow) so the MIS people see no reason to fix this on their end: <<<snip>> -----Original Message----- From: (CCI-Atlanta) Sent: Tuesday, September 02, 2003 3:25 PM To: (CBI-Atlanta) Cc: (CBI-Atlanta) Subject: RE: Cox email fails reverse DNS lookup It looks like for some reason he is trying to reverse lookup the sending domain - this is batl0s04.cbi.cox.com - however this is inside our firewall, and he will not be able to look it up from outside (it is a 10. address) The actual sending IP is NAT'd and reverse DNS lookups fail on it. <<snip>> So of course, even though I have their mail server in white list (only works in phrase checking) and Have the mail server in trusted domains, as it fails HELO/ELHO, IMail doesn't care that it is trusted. 08:29 14:34 SMTPD(0007018C) [00000292] <mydomain.com> VALIDATION: (HELO) mydomain.com performing DNS lookup for HELO domain BATL0S04.cbi.cox.com 08:29 14:34 SMTPD(0007018C) [00000292] <mydomain.com> VALIDATION: (HELO) mydomain.com received reply from DNS server for HELO domain BATL0S04.cbi.cox.com 08:29 14:34 SMTPD(0007018C) [00000292] <mydomaincom> VALIDATION: (HELO) BATL0S04.cbi.cox.com domain failed active validation 08:29 14:34 SMTP(04C80002) Got White List and Content Filter for mydomain.com 08:29 14:34 SMTP(04C80002) [cox.com] in white list So, anyone have any idea how to enable HELO/ELHO when the MIS people at the other place don't care their routing/dns is bad and this very powerful tool cannot be used because of arrogance of the sender's MIS? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Kami Razvan Sent: Friday, September 05, 2003 10:24 AM To: [EMAIL PROTECTED] Subject: RE: [IMail Forum] Verify Mail From Address v8.2 Hi; We use it and it works amazingly well. We add an entry in the header and evaluate the header later. Based on my experience no legit email has ever failed that test.
