I wonder. Do you have any data on how typical mail server software
reacts to that sort of policy? What does, for example, a Sendmail or
Exchange server in default configuration do if it tries to deliver two
mails to a destination server, the first one succeeds, and the second
one fails with "administratively prohibited"?
