Hello, Just one minor comment, since others seem to be handling the query...

Actually, there's another way you can hand a message to exim, and that is by invoking it directly, as /usr/sbin/exim (or /usr/sbin/sendmail). You can configure fetchmail to use either method. BTW, you might need to configure exim to accept invalid sender addresses from fetchmail, but I've forgotten how I did that. > > 5.

I would suspect that most programs would call /usr/sbin/sendmail, because that's a lot easier to do. Certainly elm has that filename hard-coded into it, and so does mutt. /usr/sbin/sendmail is another name for exim, which then does whatever it's supposed to with the message - typically, it'll either write it to someone's mailbox, telnet 25 to another host, or write it into its private area to deal with it later.
