There is not currently a way to handle this in the SMTP library.  It  
would be necessary to change the code to map the various RCPT TO  
commands to the responses to do this.

The SMTP error text itself is irrelevant since there is absolutely no  
guarantee it will show any useful information on any given server.

You could add a hook to do this local mailbox verification in IMP  
where you can catch these cases though.
