How does it become more preferable? Your ISP has a far fatter pipe - and a
more permanent connection - to the 'net than you have. If they happen to be
blocked because of spam origination, or RBL'd or whatever, use an smtp server
which lets you relay using authentication etc.
You'll find yourself setting up more and more such exceptions - and there's
no easy way you can parse the wide variety of 5xx errors you get in response
to a DUL bounce.
