Yes, that's the correct one.

It's an exim4 option, I can't remember the name for exim3.

Exim uses some db-files for retry data and other things (mostly in
/var/spool/exim/db) But with linux it's mostly not needed to put them
into a ram-fs. So just forget about my comment ;)

You should only scan messages comming via smtp/esmtp, you can do this by
modifying the condition o the scanning-router.

You can run exim -d9 -otheroptions to find out what exim does.

These processes all inject mails directly, as Tamas pointed out on
exim-users it's better to inject such messages with bsmtp, instead of
calling the exim binary for every single message.
