    #
    # sendmail.mc prototype config file for building Sendmail 8.15.2
    #
    # Note: the .in file supports 8.7.6 - 9.0.0, but the generated
    #       file is customized to the version noted above.
    #
    # This file is used to configure Sendmail for use with Debian systems.
    #
    # If you modify this file, you will have to regenerate /etc/mail/sendmail.cf
    # by running this file through the m4 preprocessor via one of the following:
    #       * make   (or make -C /etc/mail)
    #       * sendmailconfig
    #       * m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
    # The first two options are preferred as they will also update other files
    # that depend upon the contents of this file.
    #
    # The best documentation for this .mc file is:
    # /usr/share/doc/sendmail-doc/cf.README.gz
