This installation of Exim includes Exiscan content scanning support,
from http://duncanthrax.net/exiscan/, which is documented in
${PREFIX}/share/doc/exim/exiscan-readme.txt.  The ports tree
includes various content scanners that might be useful, e.g.
mail/p5-Mail-SpamAssassin and security/vscan.

When Exiscan is actually enabled in the Exim configure file, great
care should be taken to test upgrades, since Exiscan updates tend
to not maintain backward compatibility.

The following documentation has been installed:

    info Exim			-> Exim Specification (User Guide)
    info 'Exim Filtering'	-> Exim Filter Specification (for end-users)

In addition, plain text versions of these documents have been installed
as:

    ${PREFIX}/share/doc/exim/filter.txt
    ${PREFIX}/share/doc/exim/spec.txt

Postscript, PDF, HTML and plain text versions of these documents, as well
as a comprehensive FAQ list, are available at http://www.exim.org/ .

To use Exim instead of sendmail on startup:

*) Create exim/configure from exim/configure.default .
*) Clear the sendmail queue and stop the sendmail daemon.
*) Adjust mailer.conf(5) as appropriate.
*) Set the 'sendmail_enable' rc.conf(5) variable to 'NONE'.
*) Set the 'daily_status_include_submit_mailq' periodic.conf(5) variable
   to 'NO'.
*) Start exim with '${PREFIX}/etc/rc.d/exim.sh start'.

You may also want to configure newsyslog(8) to rotate Exim log files:

/var/log/exim/mainlog	mailnull:mail 640 7 * @T00 Z
/var/log/exim/rejectlog	mailnull:mail 640 7 * @T00 Z

NOTE TO OPERATORS UPGRADING FROM exim-3.xx:

There was a big reworking of the way mail routing works for release
4.00. Previously used "directors" were abolished, and all routing is
now done by routers. Policy controls for incoming mail are now done by
Access Control Lists instead of separate options. All this means that
pre-4.00 configuration files have to be massively converted. If you
are coming from a 3.xx release, please read the document in the file
${PREFIX}/share/doc/exim/Exim4.upgrade, and allow some time to complete
the upgrade.
