Sorry, "depend" was the wrong word. My patch adds them as a "Should-Start"
directive, which means fetchmail is started after them if they exist,
and (plainly) started if they don't.
IOW: If you do happen to have a local nameserver/mta, fetchmail is likely
to use them, so _in that case_ delay starting fetchmail for them.
