It's also possible to just not accept mail if the reverse lookup indicates that the sending IP address is a dynamic address, which you can sometimes see from the hostname. I would suggest you *not* name your hosts to contain a lot of numbers and the string "dhcp", for example ;)That would be a very bad idea I think. Doing that would lose quite a lot of small companies and individuals such as me that run a mail server but are unable to get the ISP to change the reverse DNS. For example I do have a fixed IP, but have an reverse DNS pointer which looks like 1-2-3-4-5a.foo.bar.bostream.se.
I am in the same situation. I also have three domains. Which one do I pick? I can't afford to get an individual ip address for each. Virtual servers on a single ip also will have similar problems.
Forcing everybody to send mail through their ISP (and I'm not even sure if my ADSL subscription includes such a service) would be a big loss. First of all its a philosophical thing, I think that it's very important that small shops or individuals should be able to control the services they need, the internet is supposed to be peer to peer. Second because the ISP's mess up a lot more often than I do, for example Telia, one of the largest ISPs in Sweden have been having massive mail server problems during the last week which I'm happily unaffected by.
My ISP only reciently started to think about using greylisting. They route all their mail through a filter service that I do not trust. (Too many false positives. I also expect that all this talk about "forking children" would get me on some list somewhere.)
I have more experience running mail servers than the people at my ISP. (Not their fault. They are young.)
