How to Build a New File

The following procedure shows you how to build a new configuration file.

Note - /usr/lib/mail/cf/ is now /etc/mail/cf/cf/
  1. Become an administrator.

    For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2 .

  2. Stop sendmail.
    # svcadm disable -t network/smtp:sendmail
  3. Make a copy of the configuration files that you are changing.
    # cd /etc/mail/cf/cf
    # cp

    Select a new name for your .mc file.

  4. Edit the new configuration files (for example,, as necessary.

    For example, add the following command line to enable domain masquerading.

    # cat

    Use the desired host name and domain name.

    In this example, MASQUERADE_AS causes sent mail to be labeled as originating from host.domain, rather than $j.

  5. Build the configuration file by using m4.
    # make
  6. Test the new configuration file by using the –C option to specify the new file.
    # /usr/lib/sendmail -C -v testaddr </dev/null

    While this command displays messages, it sends a message to testaddr. Only outgoing mail can be tested without restarting the sendmail service on the system. For systems that are not handling mail yet, use the full testing procedure in How to Test the Mail Configuration.

  7. ()Install the new configuration file after making a copy of the original.
    # cp /etc/mail/ /etc/mail/
    # cp /etc/mail/
  8. Restart the sendmail service.
    # svcadm enable network/smtp:sendmail
