OT - Greylisting

I ran the test that Julian sent and the welcome prompt was delayed about
5 seconds.  When I added the host I ran the test from to "access.db",
the prompt appeared almost immediately.  So, greet_delay does appear to

I ran the following two commands and came up empty:

MailFilter:/var/log# grep "rejecting commands" *
MailFilter:/var/log# grep greeting *

I have Sendmail checking against a couple of blacklists in rbldnsd and
that has been blocking about 98% of what comes in.  Is it possible that
Sendmail is doing the RBL lookup and refusing the message before
greet_delay kicks in?
