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)! -- Charles R.
