I have been updating my FreeBSD systems for many years by updating and building from source. For the FreeBSD 9.2 cycle, I decided to use freebsd-update for binary update instead. I use Sendmail + Cyrus-SASL and the freebsd-update process only installed a 'bare bones' binary. How do I compile just Sendmail from source so that it uses my /etc/make.conf for the smtp_auth components?
