Exactly.I successfully ran a mail server for a number of years without rDNS, but then was forced to get it. No drama, I have rDNS now.
But, the blocking of xDSL mail servers that are properly set up just because they aren't going through an ISP is a horrible abuse of the Internet. So is using block lists that stop legitimate mails from getting through so often.
Respect rDNS, respect SPF, those two alone would make a huge difference. Greylisting is very effective, on the whole, and you need not necessarily delay mail for too long a period.
The main reason I run my OWN mail server is that it is far more reliable than most if not all ISP mail servers that I've had to deal with over the years and I use SSL as much as I can to reduce the risks of plain old POP mail systems that sent everything in clear text -- not many ISPs will go to that level to protect user security and "VALIDNESS" of mail services.
