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.
I dunno - those are two big if's, and neither makes much of a reason for not sending email directly. I think it's fairly safe to say that _nobody_ is notified automagically just because an IP is added to some arbitrary blacklist.
