Please folks - don't argue with me - I'm the wrong person!  The 
recipient who is receiving these emails, ie the person being "bugged" is 
demanding that they are "buggable".  If they demand it and it's a 
requirement for providing them service then I have to give it to them if 
I want the business.

The users are on satellite dialup and barely have enough bandwidth to 
download a few KB of emails, they certainly can't trigger web bugs to 
trigger read receipts.

Look, I can argue against the idea easily, personally my objection is 
mail loops, but the point is that the customer demands it, and at 
present that prevents me bidding for certain types of business...  
Basically the customer just wants to repro what they got with Exchange

Cheers for ideas though!
