Given that I'm no expert, perhaps others would like to comment on this
installation approach.

Hi Chris,
As someone who has just been through a lot of exim muddles, perhaps I
can contribute here. I messed up my exim setup while moving /opt to a
new partition. So this morning I was able to try out your guide. It
works but needs a little changing patricularly for routers info.

First step: offer a default installation. Its great that you can tweak
everything but for goodness sake lets allow for people who break stuff
when they tweak.
Suggested first instruction for default setup:
groupadd exim_mail
useradd exim_mail - d /dev/null -s /bin/false -g exim_mail
mkdir -p /var/spool/mail
chown exim_mail /var/spool/mail
chmod 1777 /var/spool/mail
mkdir -p /var/log/exim
chown exim_mail /var/log/exim
chmod 1777 /var/log/exim
If there was a sed command that would extract the UID and GID from
/etc/passwd that would be great but otherwise...
"From /etc/passwd please copy the UID and GID for exim_mail and enter them
below"

Most newbies know how to tail -f a log but find all the info in syslog
confusing. Why not use a dedicated folder?

It OK to have stuff in with a header that says "You don't need to
understand this. It just works. If you are insterested, read chapters
17,18, 34, 35 amd 42 of the manual." Or some suuch discouraging note
over the essential but incomprehensible stuff.

No these don't work. If you do this, other users are denied access to
their mail. 1777 works.

This /must/ have the routers in or else exim doesn't work.
