4.4. Sendmail Configuration

If your RHN Satellite Server will serve Monitoring-entitled systems and you wish to acknowledge via
email the alert notifications you receive, you must configure sendmail to properly handle incoming
mail. This is required by the email redirect feature, which allows you to stop notifying users about a
Monitoring-related event with a single reply.
Important
Some more restrictive corporate mail configurations will not allow mail to be sent
from an address that is not recognized as valid. Therefore, it may be necessary to
configure rogerthat01@{mail domain} as a valid email address in your corporate
environment. Check with your mail systems administrator.
To configure sendmail correctly, run the following commands as root. First, create a symbolic link
allowing sendmail to run the notification enqueuer with the following command:
ln -s /opt/notification/scripts/ack_enqueuer.pl /etc/smrsh/.
Next, edit the /etc/aliases file on the mail server and add the following line:
rogerthat01: | /etc/smrsh/ack_enqueuer.pl
Next, edit the /etc/mail/sendmail.mc file and change:
"DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl"
to:
"DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl"
Then, have the alias processed like so:
newaliases
Finally, update the sendmail-cf package:
up2date sendmail-cf
Note, disconnected installs must obtain this package from the ISO.
Restart sendmail:
