As I've already said, this envelope sender munging is more broken than SPF.

Besides, speaking of forwarding problems, I've seen forwarders use an
empty envelope sender, how do your other methods cope with that?

I do publish SPF TXT RRs (hardly ever consulted in the two months
they've been in place..), but do not use it myself. I admit, I use
?all.
