I don't think this is an email client problem (ie Thunderbird). It 
appears to be an issue with Comcast. WRT: gmail. Since gmail uses iMap 
it is an entirely different protocol. With iMAP when you read an email, 
then the server is notified but in POP it occurs when the email is 
downloaded. So, with gmail, in gmail, you may see 3 unread messages, and 
the same 3 should be unread on the server (allowing for timing 
differences),. If you read an email on the server, that should show up 
eventually in the client. In POP the email on the server should reflect 
the download, and should be market read on the server, but I have seen 
many cases where it was not.

I have not read the POP spec in a number of years so my info may be rusty.
