When I try to start an Exim daemon, nothing happens. There is no process, and nothing is written to the Exim log.

Check to see if anything is written to syslog. This problem can be caused by a permission problem that stops Exim from writing to its log files, especially if you've specified that they should be written somewhere other than under Exim's spool directory. You could also try running the daemon with debugging turned on.
