Well, this is worse:

# service exim4 stop
# service exim4 start

yields a second running daemon, as root:

Debian-+  1227     1  0 Feb04 ?        00:00:00 /usr/sbin/exim4 -bd -q5m
root     17597     1  0 02:18 ?        00:00:00 /usr/sbin/exim4 -bd -q5m

and I still get the error message in the logs:
