[Mimedefang] Fw: please try again later

[Marco Berizzi]

Ohhhh I'm happy hearing you. ;-)
Ok.I will give you all the details. This is from sendmail.cf

Xmimedefang, S=unix:/var/run/MIMEDefang/mimedefang.sock, F=T,
T=S:120s;R:120s;E:5m

because I want MD socket being created under /var/run/MIMEDefang.
Is right?

This is from /etc/rc.d/rc.M (I'm using Slackware) for the MD/sendmail
startup:

# Start the MIMEDefang daemon:
if [ -x /usr/bin/mimedefang ]; then
  echo "Starting MIMEDefang daemon"
  if [ -x /var/run/MIMEDefang/mimedefang.sock ]; then
    rm /var/run/MIMEDefang/mdefang-mx.sock
    rm /var/run/MIMEDefang/mimedefang.sock
  fi
  /usr/bin/mimedefang-multiplexor -x 10 -m 2 -b 60 -i 300 -s
/var/run/MIMEDefang/mdefang-mx.sock
sleep 1
  /usr/bin/mimedefang -m /var/run/MIMEDefang/mdefang-mx.sock -p
/var/run/MIMEDefang/mimedefang.sock
sleep 1
fi

# Start the sendmail daemon:
if [ -x /usr/sbin/sendmail ]; then
  echo "Starting sendmail daemon:  /usr/sbin/sendmail -bd -q15m"
  /usr/sbin/sendmail -bd -q15m
fi

Ok? Well, this setup is identical between two machine (same HW) except
one is kernel 2.4.17 (this is fine) and the other is 2.4.18 (this is
KO). There other minor packages that are different (iptables-1.2.5 vs
iptables-1.2.6a) but I think are not involved in this problem.
The thing that I don't undestand is why till Mar 28 11:55:41 all was
fine. Since that day/time something is wrong: syslog is logging this:

This machine is a celeron 300 (mendocino) 64MB ide disk. My mail traffic
is about 20 000 mail/mounth. Today I have restarted the system, but
nothing has been changed.
I remember you that this machine is forwarding all the message for my
domain to an internal M$-Exchange.

PS: Also I don't understand why this system is able to receive message
from <>
