I was remotely testing a web page. A web page error condition invoked the embedded PHP mail() command.
To my astonishment something in Centos woke-up Exim. Exim sent the email and then became inactive again. The Exim logs does not show any start-up lines, just
- input from Apache.
- output to remote server.
- 'completed'.
Hours later Logwatch, not yet customised, also caused inactive Exim to send an email (which got rejected by Exim because it was to local user 0).
What causes Centos to temporarily activate in-active (meaning non-running) Exim ?
You don't really need an active smtp daemon to send email or deliver it locally. $ cat /etc/php.ini | grep sendmail
