Check that the server is listening on the wildcard address. Look at the
output of "netstat --inet -l". If you see an entry in the Local Address
column like "localhost.localdomain:smtp", then sendmail is only
listening on the loopback interface, not to the network. =20

If this is the case, look in /etc/sendmail.mc
(could be /etc/mail/sendmail.mc on RedHat), and there will probably be
something like DAEMON_OPTIONS('Port=3Dsmtp,Addr=3D127.0.0.1'). Comment this
out, rebuild /etc/sendmail.cf, and restart sendmail.=20

I found the following page on sendmail. It's got what I told you above,
plus what looks like some stuff on local forwarding, but I only skimmed
that.=20

Ditto. I use Postfix whenever I can, and sendmail when my boss wants it.
