We are running Exim 4.05 now for this project. Exim has no problem whatsoever
reading the alias files and delivering mail when invoked locally. The only
problem was receiving the message from the Internet.
I was fairly certain when I sent my original message that what we were wanting
was not really possible with the current implementation. Since we want the
system to be able to properly reject unknown users but additionally want to
protect each sites' home dirs, I had already begun working on other
solutions. What we decided to do was make the group of each sites' home
directory, the exim group. The site users are not members of this group, so
the home dirs are effectively not shared.
Perhaps a possible future version may use the user router directive with the
redirector router similar to the way check_local_user uses it for .forward
files. For now, this solves our problem and pushes this project forward.
Thank you to all who replied. Exim is the most flexible MTA I have had the
pleasure to work with.
