MailScanner is now working. 

1- I modified the /etc/rc.conf file to load sendmail_enable="NO".
2- Modified the incoming_queue=/var/spool/mqueue located in
/usr/local/etc/rc.d/mta.sh

TO incoming_queue=/var/spool/mqueue.in 

3- made sure /usr/local/etc/rc.d/mailscanner.sh loads on boot.

Rebooted, and it works great so far. Now to test and fine tune. 

Thanks for everyones help, apppreciate it.

I have just reviewed this doc
http://www.sng.ecs.soton.ac.uk/mailscanner/install/sendmail.shtml 

I have verified that all directories have been created.

Output /var/spool

drwxr-x---  4 root   daemon   512 Oct 18 09:31 MailScanner
drwxrwx---  2 smmsp  smmsp    512 Nov 23 10:35 clientmqueue
drwxr-x---  2 root   daemon  1024 Nov 23 10:35 mqueue
drwxr-x---  5 root   daemon   512 Nov 22 15:16 mqueue.in

Output of /var/spool/MailScanner

drwxr-x---  7 root  daemon  512 Nov 21 17:14 incoming
drwxr-x---  2 root  daemon  512 Oct 18 09:31 quarantine

According to the section "Change Commands that start Sendmail"

Two sendmail processes are needed in order for MailScanner and
sendmail
to function. On FreeBSD 5.4, sendmail on boot up is loading by
/etc/rc.sendmail with defaults specified under /etc/defaults/rc.conf.

In order to have two sendmail processes load at startup, would I have
to modify the /etc/rc.conf to override sendmail defaults by adding:

#Modified /etc/rc.conf would have these lines.

#This would take care of the first sendmail process.
sendmail_enable="YES" 
sendmail_flags="-L sm-mta -bd -OPrivacyOptions=noetrn
-ODeliveryMode=queueonly -OQueueDirectory=/var/spool/mqueue.in"

#Startup second sendmail process points to /var/spool/mqueue
/usr/sbin/sendmail -L sm-mta -bd -q15m

Sendmail is working!!!!

I had to modify the DAEMON_OPTIONS in my mc file in order to have
sendmail listen on any address (0.0.0.0) instead of just my public
address. Recompiled sendmail, then it worked. 
Issuing a sendmail -v root <dev/null works.

I thought I did this before, guess not, or sendmail just didn't get
updated properly. Who knows?

Now on to MailScanner.

No sendmail -v root </dev/null still says connection refused. I just
checked my /etc/hosts.allow file which has:

ALL : localhost 127.0.0.1 [::1] : allow
sendmail : localhost : allow
sendmail : ALL : allow

What is [::1] ? I never seen that reference.
