Update: One of my customers has a Comcast using contact that got a trouble ticket and contact info to me! I emailed the Comcast CSA with problem description from another IP and promptly received a phone call from a CSA that asked relevent and productive questions. It was such a relief just to talk to someone there that understood the problem as presented! She asked for log snippets, IP address, asked me to test a telnet session, had me send messages to another account so she could get headers. Truly, having someone ask relevent questions was refreshing. The issue is going up to admin at Comcast now. ~Katie
_____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Katie LaSalle-Lowery Sent: Wednesday, September 17, 2008 5:05 PM To: [email protected] Subject: [IMail Forum] Comcast Reverse DNS Issue Hello, For some time now our customers (both on our Imail server and their own Imail servers on our IP's) have been unable to reliably and consistently deliver email to Comcast email addresses. When I check the logs I see a response from the Comcast servers "comcast reverse DNS failure : try again later" We have reverse DNS records. I've tried phoning, emailing, chatting Comcast. I can't get beyond tier 1 tech support who neither understands DNS nor can move me up to tier 2 because I am neither a customer nor calling from an area in which Comcast provides service. I've been directed to a form to fill out to get an IP unblocked. I've filled that form out many times, noting in the comments field the actual nature of the problem. I get a response saying our IP isn't blocked. I've sent email to [EMAIL PROTECTED] and received an automated response. To add insult to injury, the automated response contains broken links. I've had Comcast customers, armed with notes, try to get their request for assistance escalated beyond tier 1. No go. Does anyone have any contacts at Comcast and/or other ideas? Thanks, Katie
