Thunderbird stopped sending and receiving email. When I tried to send I got: "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.comcast.net was lost in the middle of the transaction. Try again." My email loads on my tablet so it's not comcast. Firefox works so it's not my internet. Any clues?
