So reading the info ... basically it can't at all. An encrypted email message cannot be decrypted without the passphrase, and in the normal course of operations, we do not store passphrases. However, we may be required to store a passphrase for an account identified in a court order enforceable in British Columbia, Canada. Really - how hard can be for online services to get it - all encryption and decription should be done ON the client side with open source client that can be scrutinized. Unless this is done no assumption of security can be made.
