Comcast IP address is Blacklisted
I'm the IT guy for my office. My coworker is working from home and can't send any work emails or reply to received work emails.
This is the message he receives after attempting to send email:
"The server response is: Access denied for 188.8.131.52"
The IP address belongs to Comast and has been blacklisted which is preventing work email to pass through Comcasts servers.
My coworker reported this to Comcast last Tuesday and a case was created and escalated. There has been no response since then.
I've been through this situation in the past with other providers and was able to resolve it almost immeidately. How is this handled at Comcast? Why can't my coworker get any clear responses from Comcast? It's a big interruption and incovenience during a time when we rely on our services to work properly during this shelter in place situation.
I can't find anything new on this topic in these forums. The ones I've found are all archived.
Any help appreciated.
