He didn't specify this, but I'd guess that he also wants this action 
associated with a 'direction' of mail flow, like all outbound messages. 
  Where else can you catch them?

That doesn't work if you are sending - but you could direct outbound 
mail through a different server than inbound to control the impact and 
make it easier to determine which way the message is headed.
