+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
+
+
+Dependencies
+------------
+
+Leap SMTP Relay depends on the following python libraries:
+
+ * Twisted 12.3.0 [1]
+
+[1] http://pypi.python.org/pypi/Twisted/12.3.0
+
+
+How to run
+----------
+
To launch the SMTP relay, run the following command:
twistd -y smtprelay.tac
+
+
+Running tests
+-------------
+
+Tests are run using Twisted's Trial API, like this:
+
+ trial leap.email.smtp.tests
