I mean real user processes, not Exim processes. A user obeys "send" in
an MUA program such as Pine, say. *Any* process on the host can call
/usr/lib/sendmail at any time it wants to, in order to send a message.
Doing so creates an Exim "reception" process.

Of course, if you don't have users on your box, there are fewer of
these. But system processes such as cron send mail occasionally too.
That's why it's harder to stop mail arriving than it is to stop it being
delivered.
