Exim awoke, forwarded the email then became inactive (not running) again. I was curious how a non-running Exim can be run, solely to forward mail, then returned to its inactive state. I assume some system software identified the PHP outgoing email, and launched the only MTA installed (Exim) just to handle the outgoing email. -- Regards, Paul. England, EU.
