Interesting. It certainly has never failed to encrypt the message properly so that definitely does seem to be working. Unfortunately, the header not being encrypted is not in any way predictable. A friend may send me a message using PGP/MIME and the headers are encrypted correctly. His next message, send the exact same way from the exact same system, won't encrypt the headers but will encrypt the body of the message. I've tried to find a predictor as to what might trigger the behavior but have been unable to do so thus far. > I don't fully understand what you mean with a Windows 7 system. Does it > happen for mails that you sent out, or mails that you received? It actually happens both. There have been several piece of mail I've sent that have had the body properly encrypted but the headers are unprotected and several I have received with the same issue. As to what I mean by a 'Windows 7 system', I mean a computer system running the Microsoft Windows 7 operating system. However, this is also happening at times hen I send or receive messages from an Ubuntu system, a Fedora system, and (I tested this today) a Windows 10 system. Again, no common denominator except they all run Thunderbird with GnuPG2 and Enigmail. Anthony
