Where Mike's mechanism obstructs you not at all.Depends. Some hotel admins aren't so bright. That's the problem. Not everyone hears block outbound SMTP on port 25, they hear block outbound SMTP and stop listening. Boom, 25, 465, 587 all get turned off.Sure. But that's not Mike's mechanism. It's ignorant hotel guy's mechanism. Don't penalize Mike because some other fool does something similar but wrong.
Mike recommends a tactic that leads to idiot hotel admins doing bad things. You bet I'll criticize it for that. His mechanism breaks things anyway. I'll criticize it for that too.
If you're still doing the wrong thing, trying to talk to remote SMTP servers on TCP port 25, why should his mechanisms not punish you?It's not wrong to talk to them on port 25. It's wrong to allow unauthenticated remote users to send on your own port 25 for relay purposes.Sure it is. Same way it's wrong to have an open relay or an unsecured proxy. It isn't 1995 any more.
As I said, we can agree to disagree about what is wrong. I know your position. I still don't agree with it. Owen
