can receive, but not send, encrypted e-mail

[Roger E. Rustad, Jr.]

I just recently installed Enigmail/GnuPG on Thunderbird/Windows 2000.

I can receive encrypted mail from people, but I can't send out encrypted 
e-mail.  When I check the "encrypted" option, it still sends it out in 
lear text.  Not sure what I might be doing wrong...

Thanks in advance,
Roger
