For some reason, that i dont know encrypting mails doesnt work anymore in Mail App 6.2.


I have a valid certificate for myself and the person i want to send the message to. The certificates were issued by CAs from the internet and are meant to encrypt e-mail messages. Signing a message with my certificate works without a problem but the lock to enable encryption alsways remains greyed out.


This is what i have tried so far. Nothing worked:


.) setting the trust to "always trust" for my certificate and for the recipients certificate.


.) answering a signed message of the person i want to send an encrypted message to.


.) adding the e-mail address as a "New Preference" for the certificate in the keychain app.


.) sending myself an encrypted message doesnt work either. I can only sign it.


.) making sure that the contacts app shows a check mark next to the e-mail address (it does).


.) typing the recipients address without auto-completion to make sure the spelling matches up perfectly.


.) restarting Mail App after every change in the Keychain App.


.) restarting the Mac.


All the same certificates work on my iPhone. I can also send myself an encrypted message using my iPhone and then i can even open it on the Mac!


I am all out of ideas here.

MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)
