I think we still should HUP the deamon. It's not that much of an effort.
Maybe adding something at the top of the config file, in CAPS and with
stars and bells?
I have written a small python script that tests the configuration file
from the a central RCS repository and copies them to servers. If someone
wants it, then ask and I'll post a hacked version of it. Otherwise, it's
really not that difficult to actully do it yourself. Good exercise if
you want to learn Python -- and do, it's good ;> ... or do it in perl.

That's something else completly...
$ ps ax | grep exim | awk '{print $1}' | xargs kill -HUP
or
$ killall -HUP exim
