For IP if you deem appropriate... I run my own mail and web server, and over the last few weeks I have begun receiving messages such as this one following an e-mail to my birthmother... 550 Comcast does not support the direct connection to its mailservers from residential IPs. Your mail should be sent to comcast.net users through your ISP. Please contact your ISP or mail administratorfor more information.
If I were a Comcast customer I could protest this move by canceling my service. But I am not a Comcast customer: why should I be subject to their foolish rules and what recourse have I?
Finally, what right does this company have to inhibit my communications? Would I be pleased to find that the phone company had determined that alot of prank calls came from pay phones, and tried to "help" me by preventing pay phones from calling my home? I don't think so.
You don't mention who your ISP is, however, if Comcast is under the impression you're on a residential IP address, odds are they got this information from _your_ ISP, who is, in effect, telling Comcast to block your mail. Does your agreement with your ISP prohibit the running of servers from your account? If so, you have your answer, which is that you're violating your agreement, and Comcast knows this because your ISP has published their residential IP addresses for the express purpose of allowing other ISPs to refuse mail coming from those addresses. If your service agreement does not prohibit the operation of servers, you still should investigate whether your ISP has published their residential IP space for blocking purposes. Many, if not most residential blocking lists are based on self-published IP ranges. - Ron ------------------------------------- You are subscribed as lists-ip () insecure org To manage your subscription, go to http://v2.listbox.com/member/?listname=ip Archives at: http://www.interesting-people.org/archives/interesting-people/
