Both of the above conditions are true. I replaced sendmail with Exim and
Exim starts whenever the machine starts. I also stop and start it while I
am root after changing the configuration file or the system filter,
because if I make a mistake in a filter, restarting Exim will show errors
in the logs and I can then find my error.

It seems to be running now and I added EXIM_UID and EXIM_GID to my exim
configuration.
