That reinforces my view that Exim should continue to do this.

Absolutely (though there is no native Windows port of Exim). I have done
exactly the same - put in a couple of patches that were small and had
zero effect on the Unix version, but that's as far as I'm prepared to
go. I do not offer any support.

Me too!

Twice (to my knowledge), people have gone away with the code of Exim to
try to do that; in each case, I heard nothing more. I know zilch about
Windows (never used it, let alone programmed for it), but I suspect the
mismatch of system facilities is just too great.

You don't sound harsh. You sound completely on target. I'm right there
with you.
