If you're not receiving list mail, complain to Comcast. They're blocking us and have been doing so since about August 21st. Sorry for the inconvenience but apparently we're not alone in who Comcast is choosing to block and how they're not responding to the situation. :(  Cathy

We have been having worsening problems with Comcast blocking our IPs in the last couple weeks. This is being exacerbated by Comcast's lack of response to our numerous attempts to contact them to resolve the problem.

When an IP is blocked, Comcast bounces mail with instructions to contact a specific email address. This email address is automated and removes blocks on IP addresses contained within a message. The problem is that these IPs frequently end up blacklisted again, and too many removals will eventually cause this mechanism to start denying blacklist removal requests altogether, with absolutely no recourse.

In contacting Comcast's general support (which had no knowledge about the problem) we retrieved a phone number for their "abuse and security" division. We've made numerous calls to this number which feeds invariably into a voicemail.

We have also a couple dozen emails to Comcast's de-listing address as well as their abuse address requesting some sort of human response on this issue with information about why mail is being rejected and some sort of evidence on what kind of mail is generating complaints, so that we may take appropriate action.

Thus far the response to our requests has been complete silence, and the occasional automated reply that does not provide any real information about the problem.

By the looks of it, we're also not alone!

In the meantime I strongly recommend that if you have forwarding addresses set up to send mail to your Comcast address, you remove these and set up locally-hosted DreamHost mail users which you can download mail from via a program like Outlook or Thunderbird, or even check via webmail. If you need any assistance with this, please contact support and we will be happy to assist you.

We've also experienced Comcast blocking our listserver IP for announcement/discussion lists that are set up in our panel. As per above, we've tried to contact Comcast and explain that this server only sends to addreses which have opted-in and provides opt-out removal procedures, but have received nothing but autoresponses. Without receiving actual spam complaints from Comcast, or without the recipients taking action to remove themselves from the lists they originally subscribed to, there isn't a whole lot that can be done to fix this problem. If you have Comcast recipients on your mailing lists, they may wish to set up a mail account with a provider that does not blacklist mail quite so liberally -- just because they use them as an ISP doesn't mean they have to use them for mail, after all!

Thank you for your continued patience; we are continuing to try and get a response from Comcast on this issue and hope to eventually rectify it fully, but above are some methods that you can use in the meantime to minimize the impact of these blocks on your day-to-day usage.

Sincerely,

Karl
