In theory this would work, in practice it won't with Exim. Exim has a
build time "FIXED_NEVER_USERS" list, which in most environments contains
"root" and thus it can't be overridden.
The "never_users" option appends its value to this list. Check the
output of `exim -bV` for "Fixed never_users:". For delivery Exim
won't change its UID to one of these UIDs.

These commands are normally not necessary with the common Exim
installations, as as Exim reads the /etc/aliases as a text file each
time it does a delivery attempt. So there is no need to rebuild the
aliases and no need to restart/reload Exim.

You'll have bounces instead :) And the log file should tell you about
the failed attempts.
