FreeBSD Users

Basically you have to modify usr/src/usr.sbin/sendmail/cf/cf/machine.mc to suit your machine. I have placed my configuration file in ~/sendmail/dog.mc

Make a link to this file from the usr/src/... directory.

Then make dog.cf

Then copy dog.cf from the /usr/obj/usr.sbin/sendmail/cf/cf directory to the etc directory.
