GPGMail Beta for 10.10

You can get it here:

For some reason that’s the best link i can find…

I’ve only had it installed for a couple of days and stability isn’t terrible (one or two related crashes i think…) Up until that point i’d be living out of the services menu, which isn’t bad until you need to deal with attachments, and need other command line tools to decode / extract mime parts. Even then it’s not that bad, and will always be free.

Edit: the notes on setting up GPGTools Services are here, and the command line tool for mime is ‘ripmime‘.
