Why is my IP address being blacklisted and how do I get Comcast to clear this up?

Closed

It seems that only my ISP can remove my IP address from Spamhaus Blocklist. Can I get some help on this?

Well, the emails have a question mark avatar next to the person I send to. I double check and see if the recipient has gotten the email, they check spam and thats where its embedded. I use BlueHost for domain, work email.

How can I provide IP address without compromising security to see if Xfinity can remove from SBL(Spamhaus Blocklist)?

u/HighNoteCoffee, thank you for clarifying that detail, it helps to get us on the same page. Are you only having this issue with sending emails? Are all of your emails being impacted the same way? The reason I ask is to make sure we go down the right path towards a fix. We may need to grab some private information to troubleshoot the issue, but if we go that route we'll grab those details in a modmail.

If you have your own router and get assigned a blacklisted IP, just clone your router MAC to something else and reboot modem - boom, new IP.
