I see that as stupid and totalitarian.
If I have an Earthlink account, you're saying it's reasonable that:
- I can only send mail with my Earthlink-hosted address through their servers or servers they bless, BUT
- I can only send through their servers if I'm connected to them (and most of their peers will do the same)...
...meaning that I will likely only be able to send mail using any address when I'm on that ISP's pipe...
...an absurd situation.
You forgot all about authenticated SMTP. You can use any ISP, and authenticate yourself to Earthlink's mail servers. After you are authenticated, you have relaying privileges, and Earthlink's mail servers will sign your relayed mail automatically.
