Comcast Postmaster IPv6 issue

Mailman List Mirror (Read Only)

We're wresting with a Comcast IPv6 SMTP block and none of the Comcast
postmaster communication tools allows entering an IPv6 address. End result
= brick wall.

If anyone from the Comcast postmaster team is listening, a message off-list
would be most appreciated.

Someone will reach out. In the future, FYI: http://postmaster.comcast.net/
