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.No, it makes perfect sense but that is the one thing I fear we'll have to agree to disagree on.
Nope, Patrick is right on this one. The ruleset that appears to be in effect is: "Anything from anywhere, even if it's from a hijacked box in Korea, can forward through our server as long as it has a 'totallybusticated () ISP net' From: on it, but if one of our own customers tries to send through the server with a From: that says 'customer@vanity.domain' they can't even if they pass an SMTP AUTH check and prove they're ISP.net's customer..." And that's borked and wrong.
The solution presented here is not only not a solution, it is also a problem.Okay, then I suppose I don't understand the problem. How exactly do you mean?
See above - would you consider forwarding mail from outside ISP.net space without an SMTP AUTH check just because it claims to be 'From @ISP.net'?
