The daemon only handles incoming mail, or in other words waits for incoming connections from other mail servers. Outgoing mail is sent on demand, or in other words a connection is made to a mail server or relay as and when required.

Had a surprising event on C 6.5.
Exim was the only MTA installed. It was partially configured (with ACL, Router, Transport) and definitely not running.
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 ?
