Without knowing more about your particular setup I can only give a
generalization: protect any and all computers on your netblock with a
packet filtering firewall of some sort.

I dunno - other people should be able to answer.
If you don't have load problems running the queue that often I say go for
it.

1) exim is easier to configure
2) exim has more functionality in some areas (but less in others - I've
heard rumors that one can get sendmail to play tic-tac-toe via email using
only sendmail.cf), particularly regarding queue management (sendmail has
none).
