Then you need to replicate what `/etc/rc.d/sendmail' does.  You have the
code to that script, you also have `/etc/defaults/rc.conf' as a guide of
the defaults supported by FreeBSD.  Happy hacking :)

I'm not interested in rewriting `/etc/rc.d/sendmail' from scratch, so
other than a few pointers like the following, I'm out of the thread:

Here you started a sendmail process which listens for connections to
*all* interfaces.  That's probably ok if you plan to accept incoming
SMTP connections on _any_ interface, i.e. because you are running a
Sendmail server accessible from outside.

On my laptop this would be replaced by:

	/usr/sbin/sendmail -L smtpd -bd -q30m \
	    -ODaemonPortOptions=Addr=localhost

Note the use of the -O flag to make sure Sendmail is only listening on
the localhost:25 port for mail submission requests.

Then you have to start a *second* Sendmail instance, to flush the local
`clientmqueue' and forward the messages you see as `Deferred' when you
run the `mailq -Ac' command:

Now you have to run a second Sendmail instance, i.e. with:

	/usr/sbin/sendmail -L mailq -Ac -q10m

NOTE: The `smtpd' and `mailq' arguments to the -L options are not the
standard names FreeBSD assigns to these processes.  They are just the
ones I use on my laptop.

Since you are using a custom, local sendmail startup script, that's
about the best I can write to get you kickstarted.  For more help with
the way Sendmail operates, you can always refer to the ``Sendmail(TM)
Installation and Operation Guide''.  A copy of the guide is conveniently
installed by the FreeBSD installation process at:

	/usr/share/doc/smm/08.sendmailop/*

Good luck with the startup scripts.  I don't really understand why you
insist on rewriting something which works(TM), is featureful and easy to
extend, like the rc.d scripts, but that's besides the point :-)
