Local MTA usage and configuration (Exim)

Like Postfix, we have Exim, which is another MTA.

Where Postfix is powerful and has its focus on security, Exim is known for being extremely customizable, and with a pedigree that goes all the way back to 1995 (inching out Postfix by three years). It's been the favorite of the Debian project for years, and, as a result, a lot of the documentation on setting up a mail server references Exim.

Also, like Postfix, this won't be a long section on fully configuring Exim, as that would require something much longer than a section, chapter, or realistically a book when done right. Instead, we're going to look at some configuration, the Exim log file, and what happens when you try to send a message from your local system.
