It's a two step process. In the first step the CalcRecips handler builds a recipient list. Assuming you don't have a custom MemberAdaptor, and you probably don't, this list is in a hashed order, i.e. pseudo random.
Step 2 occurs in the delivery handler, SMTPDirect. Here the above list is split into up to 4 sublists containing
1 - all the addresses in the .com domain 2 - all the addresses in the .net and .org domains 3 - all the addresses in the .edu, .us and .ca domains 4 - all other addresses
Within these sublists, the original pseudo random order is preserved.
Then the sublists are processed in a hashed order, but since we know the keys in this case, we know the order (at least with python 2.4), and it is 4, 1, 2, 3.
So basically the recipient addresses are all the 'other' domain addresses in a pseudo random order followed by all the .com addresses in a pseudo random order followed by all the .net and .org addresses in a pseudo random order followed by all the .edu, .us and .ca addresses in a pseudo random order.
