I am getting messages from Comcast that our mailserver has been blacklisted. I can submit a request to Comcast with our mail server IP to be taken off this list. Where can I find the mail server IP? I checked throughout hSphere but couldn't find it.
This is still happening. Has anyone made a request?

The problem is mostly forwards. We are trying to figure out a way to stop forwards to these big ISPs. Comcast just makes it bad by not supplying enough information.
