Now that you've written a .mc file for your host, it's time
to generate a sendmail.cf file.
Save your .mc file in the cf/cf directory.
Run this command:
m4 ../m4/cf.m4 filename.mc > sendmail.cf
(Of course, replace filename.mc with the name of your file.)
As root, move the sendmail.cf file from the
cf/cf directory to /etc/mail, make it mode 644,
and make a symlink to it from /etc.
(You may want to back up your existing sendmail.cf first.)
