I installed Enigmail some time ago; out went all the formatting. OK I thought, I can live with that; but on inbound messages, Enigma provides me with a blank message. I've had to change my setting on the server, a Comcast SMTP server, to postpone deletion of the messages, even those that have been downloaded to my T-bird client. I unplugged Enigma; it disappeared from my menu bard; but, I still often get messages w/o any content. Someone, please point me to instructions on how to complete disengage Enigmail from Thundarbird.
