I've abandoned sendmail, and installed qmail. My only problem is aliases
don't work. I have the files:

/home/alias/.qmail-postmaster
/home/alias/.qmail-root
etc...

Mail to root, etc, does not get delivered to the address in the files (or
to root), but there is no bounce either.

Obviously, there is some config problem. But, I don't know where to look.
Any advice?

namaste,
Mark
