WOW!!!  This is about all I can say.  I can't believe more people are
not talking about greylisting and trying to include this in their
installations.  I have looked at Jonas' greylisting implementation but I
could not get around the O_EXLOCK flag, YET!  Wish I was a little better
on the database side. =:(  I am using the basic code provided by David
and will start looking into adding features in a couple of weeks.  

Here are some quick stats...

First 24 hours of greylisting:
15120 Tempfailed messages
480   Delivered, grepped on stat=Sent and excluded spam messages
352   Relabeled as spam (grepped for '***SPAM***') by SA 2.61 
1558  Blocked by Spamhaus (only BL I trust) with Sendmail

2390  Messages that were resent by remote MTAs
1910  Messages labeled/blocked because they met our spam criteria
12730 Messages that did not resend, hmmm... maybe SPAM!!



Also, should I be worried about any pitfalls of the basic implementation
by David.  I read the "official" greylisting site and figured I would
only be delaying any messages, not blocking them.

David, thank for developing/supporting a truly great product.  I hope
you are doing well with your company as you deserve the bling bling.
