Now we're getting somewhere.

I know that, for whatever reason, I will not receive DSNs from "P".
This means I will never send mail to "P".

Now, I send mail to "F".  How should I know it will forward it to "P" ?

I don't, and I don't care.  What I do care about it that "F" uses
_my_ name as return address.  I carefully avoid a problem but that
user at "F" decides he knows better and uses my name to do whatever
he likes.

Again: I don't care if he forwards the message to "P". Just don't
do it in my name.


The point is: forwarder-old-style is bad, even without SPF.

Sorry, this list is to discuss SPF, not to criticize RFC821 and 2821.

Wasn't it you that wrote

" Let's compare this as it is today, without SPF.  That's how 99.9% of
  the recipients operate, so it is what we have to compare any argument
  of loss of function.
"

?  If so then I'm sorry.
