Found the solution from Simon http://mail.python.org/pipermail/mailman-users/2002-January/016541.html To fix this you will need to tinker with /usr/share/sendmail-cf/cf/redhat.mc and look for:
dnl This changes sendmail to only listen on the loopback device 127.0.0.1
dnl and not on any other network devices. Comment this out if you want
dnl to accept email over the network.
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')
Do what it suggests and comment (dnl) out the 'DAEMON_OPTIONS' line and save
the file. Then 'make redhat.cf' and 'cp redhat.cf /etc/sendmail.cf'
-----Original Message-----
Redhat 9, fresh install.
Sendmail accepts connections on localhost, but not through the external IP.
I'll try telneting to port 25 from another machine and I get connection refused. The
problem occurs with the firewall (iptables) on and off.
