Comcast Blacklisted our Mailserver

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.

Thanks.

You can find it in in the dns name, or just go to command prompt and type ping mail.domain.com and it will return the mailserver IP there as well.

mail4 has also been blacklisted w/ comcast. What is the status on this?

This is still happening. Has anyone made a request?

Connected to 206.18.177.26 but sender was rejected.

We have emailed comcast about mail4 and we should have this issue resolved shortly.

We have contacted comcast regarding that IP as well.
We are waiting to hear from them, and we expect them to do shortly

Comcast is blocking the email from 204.14.107.1 again.

Can Jodohost please get a resolution on this?

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.
