Guide Review - GPGMail 1.1.2 - Mac OS X Mail Add-On
GPGMail adds much-needed PGP-compatible secure messaging to Mac OS X Mail. Nice Mail integration makes message singing and encryption easy, and the support for both plain text and OpenPGP MIME messages provides flexibility.
If you lack a key, GPGMail can try to retrieve it from keyservers automatically. GPGMail also selects the appropriate private and public keys automatically based on the email account you use to compose a message and its recipient.
Of course, reading, verifying and replying to signed or encrypted emails is just as easy and convenient in GPGMail.
If anything is missing from GPGMail, it is mostly more involved and specialized functionality like partial encryption or forwarding of signed messages without losing the signature.
A nice feature would be per-recipient defaults for the message format or whether to encrypt at all. If this resulted in a better key selection dialog, it would be even better.
