The following header line: Received: from static-96-254-126-11.tampfl.fios.verizon.net [96.254.126.11] by windows12.uvault.com with SMTP; Wed, 12 Aug 2009 08:26:40 -0400
Hits the HELO_DYNAMIC_IPADDR rule. I tested it this way: $ perl -le 'if ("static-96-254-126-11.tampfl.fios.verizon.net" =~ /[a-z]\S*\d+[^\d\s]\d+[^\d\s]\d+[^\d\s]\d+[^\d\s][^\.]*\.\S+\.\S+[^\]]+/) { print "Yes" } else { print "No" };' Yes But the address doesn't appear to be in a dynamic block. And it doesn't look like a dynamic address pattern to me. Bob
