Mmhhh, it has to do a dns lookup on the receipients if it wants to deliver
the Email (you're probably thinking no lockup on the sender, which you can
set as trusted).
One option is to just blindly accept everything and spool it. You end up
with a lot of spool and disk I/O that you really didn't have to do if you
had done direct delivery from memory.
That said, those are exim concerns and I have a separate thread about this
on the exim list.
