+Leap SMTP Relay
+===============
+
+Outgoing mail workflow:
+
+    * LEAP client runs a thin SMTP proxy on the user's device, bound to
+      localhost.
+    * User's MUA is configured outgoing SMTP to localhost
+    * When SMTP proxy receives an email from MUA
+        * SMTP proxy queries Key Manager for the user's private key and public
+          keys of all recipients
+        * Message is signed by sender and encrypted to recipients.
+        * If recipient's key is missing, email goes out in cleartext (unless
+          user has configured option to send only encrypted email)
+        * Finally, message is relayed to provider's SMTP relay
+
