Why can't the system tell which distant users are valid?  Why can't
there be a a /var/dcc/userdirs/esmtp/ directory
if is valid?  (That's what I meant about
odd directory names.)

Why can't distant users have access to the files?  Two mechanisms seem
effective to me.  One is with symbolic links accross NFS.
You could change the script you now use that builds your virtual
alias table to also create symbolic links over NFS.  For example,
you could make /var/dcc/userdirs/esmtp/ be
a symbolic to /automount/

Another mechanism for remote access to the files might be the CGI
web scripts I'm working on.
