5. INSTALLATION
---------------

There's an excellent MIMEDefang-HOWTO contributed by Mickey Hill
at http://www.rudolphtire.com/mimedefang-howto/.  It explains
everything in this README in much greater detail.  Anyway, on with it:

1) Sendmail

You must be using Sendmail 8.12.x or 8.13.x
-------------------------------------------

Obtain the latest Sendmail 8.12.x or 8.13.x source release from
http://www.sendmail.org.  Unpack it.  If you are building 8.12.x,
add the following lines to devtools/Site/site.config.m4:

        dnl Milter
        APPENDDEF(`conf_sendmail_ENVDEF', `-DMILTER')

This enables the mail filter feature.  (For 8.13.x, Milter is enabled
by default.)

Go ahead and build Sendmail following the instructions in the Sendmail
documentation.  Install and configure Sendmail.

You *MUST* run a client-queue runner, because MIMEDefang now uses deferred
mode to deliver internally-generated messages.  We recommend running this
command as part of the Sendmail startup:

        sendmail -Ac -q5m
