As a user of localpart macros, I would be unhappy about this. Why do I 
use localpart? I have a fail rule that (essentially) says that invalid 
users in my domain may not send mail (from anywhere). This cuts down on 
invalid mail and allows me to be laxer about allowing forwarders that 
don't do SRS.
