Hi Cyber,

So there's no /bin, etc., as we know it.

I think execvp(3) is being used, so PATH is searched?

Why is that sendmail found?  What's significant about $HOME?  Why
doesn't it recurse instead of finding the real sendmail?  There's the
`env sendmail' trick, but that's just searching PATH, which I thought
nmh was doing anyway by using execvp(3).

Cheers, Ralph.
