That did the trick! Not only that, there's a comment in the sendmail.mc file just above that line -- only as a non-techie I never looked in sendmail.mc While I was at it I also dnl'd out the FEATURE("accept_unresolvable_domains") line. I believe my access file is tight enough - its been bouncing lots of attempted open relaying for months. Dick

Yes, exactly. Red Hat (or Sendmail, I forget) changed the default for sendmail to listen only on 127.0.0.1, to prevent insecure default open mail relays. This is mentioned in the Red Hat 7.3 Release Notes....
To fix it, edit /etc/mail/sendmail.mc. Find the line with "Port=smtp,Addr=127.0.0.1, Name=MTA". Comment it out by putting dnl at the beginning of that line. Then regenerate the /etc/sendmail.cf from the mc file like this:
m4 /etc/mail/sendmail.mc > /etc/sendmail.cf
And please limit access to sendmail properly so you don't become an open relay (/etc/mail/access)!
