Comment (by rransom):

 Replying to [comment:14 isis]:

 > There still is not a mechanism to include the client's email address in
 the signed portion of the message. I'm not exactly sure what adversarial
 behaviours that was intended to protect against.

 Signing the intended recipient's e-mail address prevents the attacker from
 querying BridgeDB until it receives a signed message containing a
 malicious bridge, and then re-sending that message to one or more targeted
 users.  (If you don't sign the destination e-mail address, there's not
 much point in signing BridgeDB's e-mails at all.)
