Using the vocabulary from my previous message, I believe Hadmut
Danisch is arguing as follows. He's agreeing that sender domain
tracking is desireable, but at the same time he thinks that
MTA-chaing tracking is more practical. By requiring all mail from a
domain D to be injected via an MTA blessed by domain D, MTA-chain
tracking achieves sender-domain tracking. So he's asking, why not
impose such a requirement?
Exactly. That's it. :-)
My only concern is this. Networks often block outgoing connections
to port 25 (and for good reason). Pop-before-smtp and/or
authenticated smtp don't help with this problem. How do we deal with
this problem? Maybe requiring smtp-over-SSL in these situations will
work (most MUAs seem to support this now). However, this solution
assumes most "ISP-like" networks will allow port 925 traffic to go
out, I don't have 1st-hand experience, perhaps even this won't work.
I didn't understand what you wanted to say. Where exactly do you
see a problem?

Hadmut
