My recommendation: install the sstmp rpm package (it is available from
EPEL) and remove sendmail.  ssmtp is happy to accept a IP address for
its smarthost.  It does not handle mail delivery and thus it is much
simpler to configure.  If you don't uninstall sendmail use the
alternatives command to switch the sendmail binary symlink to use the
ssmtp one.  Postfix too should handle an IP in the relayhost field.

If you don't find your answer in the above thread or this message, I
recommend you consider hiring someone for the work.  Sendmail has its
charms, but ease of use isn't one of them.  Fortunately there are many
people who have a deep and painfully acquired understanding of it, I
can point you to several if you wish.  .
