No, 100s of 1000s of not-so-clued users have vanity domains. Have you checked how many domains are registered on a daily basis these days?I believe you are exaggerating, like I usually like to do. My point isBut that's OK, we should tell people one thing (use your ISP's server to send mail) and do another (block them from sending mail through their ISP's server).
The cost of allowing these servers to stay "open" is extremely high, andWho said "open"? There are lots of ways to keep spam from your network down.
If you have a mail server and allow it to send mail, it can be abused. All you can do is try to make it harder to abuse. One of the ways we (the collective "we" who run the Internet) have decided to do this is by forcing people to send outbound mail through their ISP's mail server, not through random open relays.
If the ISP wants to use SMTP AUTH or other mechanisms to lower abuse, that's fine. But to say "only allow ISP.net from addresses - but allow them from anywhere on the 'Net" is kinda ... silly.
