I don't know if this can be an valid assumption. While I realize that 
there is a disbalance between receivers and senders, outbound and 
inbound MTAs are different in too many cases. The question would be 
better asked: "if this an MTA". If it is not an MTA, then why is it 
sending mail directly? Of course the easiest way to figure that out is 
because this MTA is also an inbound MTA. But if we would have a 
different way of doing so, you don't need that.

I agree with SUBMIT. I would add that if its not an MTA, why isn't it 
using its local MTA with whatever authentication method it has.
