Correction: It's cable.comcast.com (not .net) and it turns out that that is the domain used by comcast employees not customers. our mail gets delivered to comcast customers just fine, just not to comcast employees. I have to say that the tier 1 person I talked to was fairly clueful regarding possible issues delivering to comcast customers, but she didn't have any knowledge about the employee domain. If postmaster@cable.comcast.com sees this, please give me a call: 435.636.0069. I'd like to get this resolved ASAP.

When I try to us the automated form to unblock my server's IP I get:

******* 67.22.175.244 We have received your request for removal from our inbound blocklist. After investigating the issue, we have found that the IP you provided for removal is currently not on our blocklist.

We need the IP address currently blocked to further investigate this issue. The IP address is a number separated by decimals and is located in an error code starting with "550" in the returned email from Comcast. Please verify the IP(s) and resubmit your request to http://postmaster.comcast.net *******

and yet I consistently get:

Remote host said: 554 Transaction Failed Spam Message not queued.

when trying to send any email from the above mentioned IP.

Please contact me via efinley at emerytelcom.com (from a non comcast address so I can email you back) or directly @ 435.636.0069
