That makes it look like comcast is having an issue specifically with charter. I 
would be curious to know if you can receive mail from other charter accounts. 
Is there anyone else you know on that service who can send you a test?

What's also odd is that you are not having issues with forwarded emails or the 
PLUG mailing list. PLUG sends emails on behalf of the sender which can cause 
some email services to silently reject the message. I have a similar issue on 
this proton account when other proton users post to PLUG. 

It is possible that comcast is refusing to accept that the issue is on their 
end because something they expect to see is missing from your charter message 
headers. The trick is getting past their T1 support team and getting someone 
who will actually diagnose the issue. Failing that, your only other option is 
to lawyer up.
