>Description:
      The mail chapter of the handbook incorrectly specifies the method of disabling sendmail.  In particular, the rc.conf variables are different for RELENG_5 and later (because sendmail_enable="NONE" is deprecated; see rc.sendmail).

Notes:
- I don't know my way around FDP very well.
- Needs review from somebody who knows their way around sendmail and its rc.conf vars.
- I used "FreeBSD 5.0-STABLE and Later" as title; perhaps there is a better choice.
- Since the warning (see patch) applies to all versions, I moved it to the top of the section and tweaked it a tiny bit.
