Most of us think, if we don't pause to reflect, that the envelope
sender is applied by sendmail or qmail-inject when the mail is
submitted. This weird thing where people read mail on their PCs is
foreign to me, and I tend to overlook it. And in that sort of
environment, envelope sender really *is* less likely to be wrong. But
it's such a small minority these days it hardly matters, in the real
world.
Also, there are a number of institutions and ISPs that insist on their
users relaying through their servers, and they make sure the envelope
sender is valid. This may still be a significant population.
But generally I agree, it would be *much* better to use the from:
header. I've thought about going in to patch it some time, but it
hasn't made it up the priority list.
