there is at least one reason for not sending email directly:
if the server IP address is added to some blacklist like SORBS, the notification is sent to the contact address of the reverse zone. If the server is under the ISP's maintenance, the ISP will (supposedly) notice this event and try its best (haha) to remove the server address from that blacklist.
If the end-user's fixed IP address appears in SORBS list, the user will not notice it, and it will take much more time before it's removed.
interesting, is there a business case behind? How much would one pay for a reliable and SORBS-free mail relay service? It's actually quite easy to build :)

Anyway, who's going to send email directly from a broadband connection, instead of using the ISP's relay? :-)
Provided everything is properly set up, why shouldn't they?
