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.
