Want some filezz? Let's see what I have:

main.cf:

transport_maps = dbm:/etc/postfix/transport
# transport to the inside

relayhost = [mail.mydomain.de]

mynetworks = 127.0.0.0/8 172.30.2.2/32 172.30.3.1/32 10.x.x.x/32 195.x.x.x/32
# localhost, both interface, and some other hosts
# only used, if VirusWall DOES NOT scan!

mydomain = mydomain.de
mydestination =
smtp_always_send_ehlo = yes
smtpd_banner = $myhostname ESMTP
myorigin = $mydomain

I have master.cf.nosmtpd AND master.cf.smtpd

% diff master.cf.nosmtpd master.cf.smtpd

70,71c70
< localhost:10025
< inet n - - - - smtpd

---
> smtp    inet  n       -       -       -       -       smtpd

and the /etc/init.d/sendmail or postfix script:

case "$1" in
 'start')
  ISSMTPON=cat /etc/iscan/pkg/ISSMTPON
  if [ "$ISSMTPON" != "1" ]; then
   cp -f /etc/postfix/master.cf.smtpd /etc/postfix/master.cf
  else
   cp -f /etc/postfix/master.cf.nosmtpd /etc/postfix/master.cf
   /etc/iscan/sendmail
  fi
  /usr/sbin/postfix start
 ;;
 'stop')
  for i in /bin/ps -ef | grep "/etc/iscan/sendmail" | grep -v grep | awk '{ print $2 }' do
   if test "$i" ; then
    kill -9 $i
   fi
  done
  TMPDIR=/tmp
  if [ -d $TMPDIR ] ; then
   rm -f $TMPDIR/smtp* $TMPDIR/msg* $TMPDIR/binh* $TMPDIR/uu*
  fi
  /usr/sbin/postfix stop
 ;;
 *)
  echo "Usage: $0 { start | stop }"
  exit 1
 ;;
esac
exit 0 

• make viruswall listen on port 10025
• tell Postfix to use:
  • content_filter = smtp:127.0.0.1:10025
• Duplicate the smtpd line in master.cf and change the port to 10026
• make viruswall reinject using 127.0.0.1:10026
