Seriously, don't do it. Rewriting the empty reverse-path to anything
non-empty means you are a danger to yourself and others. The empty
reverse-path is used on bounces for a *reason*.
I have been known to make a complaint to ISPs when I've seen systems
doing what you plan, asking them to be disconnected since they are a
denial of service attack waiting to happen.
If you really can't get the ISP to fix their broken server, then just
use a mail smarthost elsewhere. Or send mail *directly* perhaps?
