> In order to address this interoperability issue in a standards centric approach, the proposal is the addition of a new SMTP command to allow the retrieval of a recipients public key prior to the transmission of a mail. This will enable the sender to encrypt the email content before the same is transmitted through the existing SMTP commands.

This requires the MUA to be a full MTA not just an MSA passing off outbound
traffic to a real MTA,  Not the current usual architecture.

It also doesn't work with traditional-forwarding, I think, unless the forwarder
decrypts and re-encrypts.
