outgoing encrypted mail storage

I am using GPGTools integrated with Mac Mail and I had a question regarding how encrypted outgoing mail is stored locally.

If I encrypt a message using my friends public key, I shouldn't be able to decrypt that message without the private key. However, I can still read encrypted messages sent to my friend after inputting the passphrase for my key. I've read elsewhere in discussions that the locally stored outgoing messages are encrypted, but in order for me to read them, I need the private key.

So, are outgoing encrypted messages essentially encrypted twice? Once with my friends public key, which is then sent out to him, and then once with my public key, which is the version stored locally?

    Hey Mike,

    what you write is absolutely correct. In order for the message author to be able to read sent mail at a later point in time, all outgoing mail is also encrypted with his / her own public key, aside from the recipients public key.

    All the best,
