[Declude.JunkMail] Problems with Comcast and the CBL

[Dave Doherty]

Note: posted to IMail and Declude lists --------------------------------------- Hi, all- For those who have been following the Comcast threads, I had Comcast blocking me also. I met up with a couple of very helpful and courteous people there. The tech support person who called me back was willing to learn about the problem, and when I explained about IMail's - what do you call it? - domain spoofing? - and that it was normal behavior, the fellow whitelisted me permanently without further effort on my part. This is the same problem that eventually lists most, if not all, all IMail servers on the CBL - IMail says it's mail.whatever_domain_is_trying_to_send.com, and they object to lots of FQDNs from the same IP. Because they treated me fair and square, and handled the problem expeditiously, I am providing the contact method only to those who experience the problem. I don't want to swamp a good contact with calls and have him become unavailable. I am thinking about is compiling a list of IMail IPs to send him. If there is any interest in this, I'd be happy to be the conduit. Don't post your IP's here, folks, bugt do let me know if you're interested. If there's enough interest, I will contact him directly and see whether Comcast is willing to get a large whitelist from me. If so, I will create a web page where you can submit your IPs, and I will set up a verification mechanism to assure that we don't allow spammers to post their IPs on that page also. Unfortunately, even if we do this for Comcast, the CBL folks are categorically not interested in whitelisting IMail servers preemptively. Therefore, you WILL lose traffic to those guys, as I did. -Dave Doherty  Skywaves, Inc.
