Hello,
The link says as follows:
You have been blocked from emailing the Comcast network because we have determined that you are sending email from dynamic/residential IP space. Comcast does not allow residential/dynamic IP addresses to directly connect to our mail servers. In most cases, Comcast will classify your mail server's IP address as dynamic if the reverse DNS does not comply with standard static naming conventions.
How do I get my IP removed from the blocklist?
It is important that you ask your mail provider to review the settings of your email server to ensure it is set up correctly so that it is not blocked by Comcast in the future. When contacting your email administrator, you should include the error message contained in the email which alerted you to this problem. This error message contains important information to help your email administrator resolve this issue. Removal requests can be sent to
Comcast.net Blocked Provider Request Form and will require the IP address of the blocked mail server. Requests submitted through this form are monitored 24 hours a day, 7 days a week to ensure a timely response.
which is obviously a mistake since you have a static IP. Although comcast says your ip isn't blocked, it obviously is somewhere in their system. Unfortunately, as much as I hate to say this, there isn't anything you or I can do. They have somehow incorrectly categorized the ip and the best way to deal with it is to contact them, by the provided form or otherwise, make sure they remove it.
