Install postfix from ports. It does NOT install files to the same place
as sendmail with the optional exception of /etc/mail/mail.conf which
provides redirects to the postfix versions.

Also read what postfix says during installation. Needs a bit of info
added to /etc/rc.conf.

Add "NO_SENDMAIL=1" (just define it) to /etc/make.conf and a "make
buildworld" will not build sendmail. Not certain how to surely remove
sendmail once its installed.
