Only provide the <postmaster@FreeBSD.org> address for contacting the,
er, FreeBSD Postmaster team :) Also, leave just David Wolfskill's name
there, since Jonathan Bresler kindly acknowledged that David's been
doing a great job for the past year and has not needed assistance.
Enclose the FreeBSD.org domain name in <hostid> tags by blackend's
suggestion.
