Add support for encrypted subjects
Since Enigmail 2.0 it is possible do encrypt the subject of an e-mail. The subject is copied to the encrypted body of the e-mail and is replaced by a dummy text. Upon decrypting the dummy text gets replaced by the subject.
This feature is not supported by Schleuder, i.e. the encrypted dummy text does not get replaced if one sends an e-mail to a schleuder-list with this feature enabled.
Moreover, I had the problem that, if I wanted to send commands to foo-request@domain, I got the error message "Your message didn't contain any keywords, thus there was nothing to do."
After disabling the encrypted subject, I was able to successfully send commands to foo-request@domain. So I consider this a bug.
I would be pleased, if you could work on this, because I think encrypted subjects are a great improvement in reducing meta-data.
