The proposed solution is to tunnel mail through the corporate server, by proving your right to relay via SMTP AUTH or else via a VPN. To make this work well requires support for SMTP AUTH and probably STARTTLS (unless the company implementing this proposal wants cleartext passwords flying over AOL's network) for all domains which want to support Paul's proposal. This isn't necessarily all that unreasonable, but should be spelled out more clearly, and makes implementation much more involved.Precisely. It's only an issue for those who implement the feature. Another thought that came to mind was a sort of hybrid between this and the central registry of trusted servers.
If a large ISP, say AOL, implements this, and I operate the mailserver with users who send (relay through me) mail with a from address of their (legitimate) AOL account, I'm choosing to ignore the feature entirely, but it's still affecting me and my users. If a large ISP, say AOL, implements this, and I'm an end-user trying to send mail with a from address at my (legitimate) AOL account, I'm choosing to ignore the feature entirely, but it's still affecting me. I know this isn't what you're looking for, but individual domains aren't so isolated that you can implement this sort of thing without zero effect on other mailservers. You really have to solve the whole problem before it becomes usable at all. I'm not saying it's an unsolvable problem, just that these two issues need to be better addressed before it's a usable suggestion. ----ScottG.
