A note on compatibility between various email client

In our tests we found that email encryption and decryption worked successfully between all clients. These tests were conducted using external keys generated with GPG as well as with keys generated with SELS. However, for email signing we found that there are problems with signature verification for specific combination of email clients. Currently, this problems exists when encrypted and signed messages are sent from Thunderbird to Emacs or from Mutt to Mac Mail. Specifically, the email client may indicate that the message is not signed while, in fact, it is. Users can, however, use gpg commands on the received message to verify the signature. This problem was seen for tests with and without SELS; i.e., the problem is not caused by SELS.

For now we believe this to be a minor problem but we will continue to diagnose it and find solutions. In the meanwhile, please for occasional difficulties with signature verification.
