Either point to your ISP's mail server as your SMART_HOST (DS in sendmail.cf) or have the freebsd box announce itself with a valid hostname that you have a right to use (Dj in sendmail.cf). Using a SMART_HOST is the recommended way, there's a commented out example in src/etc/sendmail, but leaves you at the mercy of your ISP. Mine provided an unqualified hostname, 'mail', which was resolvable only through their local DNS and kept changing the real machine it pointed to. For the second option, you pretty much have to own a domain and have it hosted by someone who provides an A record. -- I've always wanted to be a dilettante, but I've never quite been ready to make the commitment.
