I run exim through inetd.

It's fetchmail I'm worried about. The man page says that it's better
to use SMTP, as opposed to running a command:
-m <command>, --mda <command>
(Keyword: mda) You can force mail to be passed to
an MDA directly (rather than forwarded to port 25)
with the -mda or -m option. Be aware that this
disables some valuable resource-exhaustion checks
and error handling provided by SMTP listeners; it's
not a good idea unless running an SMTP listener is
impossible.
I'm not really sure if that's true though, because inetd simply runs
/usr/sbin/exim -bs. I don't really understand whether or not
fetchmail sends SMTP commands to the --mda command. If it does then I
expect I could just use '--mda=/usr/sbin/exim -bs', otherwise I'll
stick to the listener.
