What Section 3 of draft-yao-eai-deployment-03 recommends is to 
generate an alternative address and have it stored on the (sender) 
server-side.  The user does not have to bother about that alternative 
address as the server puts it in.

Are you suggesting using VRFY to get the alternative address from 
another SMTP server?
