Uhh, Chuq, from the man page:
disable_dns_lookups
Disable DNS lookups. This means that mail must be
forwarded via a smart relay host.
AFAICT Postfix will only do DNS verifies if you set one the
(E)HELO/MAIL FROM: etc checks as detailed here:
http://www.postfix.org/uce.html#smtpd_helo_required
And unless you set that, Postfix does not DNS verifies until
attempted delivery time.
