The greylisting is presumably handling tuples of (sender, recipient,
source-IP). So the milter can't do the TEMPFAIL until RCPT TO: time. The
delay_checks feature also delays DNSBL checks until RCPT TO: time.
However, since the DNSBL checks are configured directly into sendmail's
configuration file, they're going to happen before the milter "sees" the
recipient address.

Just curious; why would you want this the other way around anyway?
