I had a session yesterday w/Mr. Med and he restored my (accidentally deleted) primary email account and its messages, but now I can send emails from that address because I get an error that the Thunderbird-supported address cannot be connected to the Comcast server. (My secondary Thunderbird-supported email address works w/Comcast just fine.) I spent the last hour+ on telephone w/Comcast and was told it was a Thunderbird connection problem. Please help.
