Sendmail is not present on the server. Exim is the only MTA. 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.
