No, there is another one. It was (is?) some kind of operating system for
a MIPS risc processor. I know no more about it, but I have had
misunderstandings in the past. That was why I was checking.

I know. For this reason, I had hoped that somebody would write the Exim
book. There was one attempt, but it foundered, and in the end I had to
do it myself. The general style of the book is indeed supposed to be
different to the reference manual, but I am not the right person to tell
you how well I succeeded. Maybe somebody else on the list who has read
it can comment.

I entirely agree. However, the book does not contain a full reference
manual because it would be too long. It omits some of the very esoteric
features, but does contain almost all of the "common" things.

The only "user level" stuff in Exim is filtering, and for that I wrote
the document "Exim's interface to mail filtering" with end users in
mind. Everything else is for the Exim admin.

Sorry, you lost me. I have no idea what a .htaccess file is. It is not
an Exim thing.

No it can't! Exim is a Unix program. There's no way it could be made to
run under RiscOS. There's some big misunderstanding going on here. My
guess is that you are in some specific environment provided by an ISP
that happens to use Exim, but there's other stuff involved as well about
which I know nothing, but which you assume is standard with Exim. That's
just a guess, of course, but I'm convinced we are at cross-purposes at
the moment.
