Milter-greylist

Hi all,

	Sorry if this topic has been covered ad nauseum already, I was unable to
find archives for this list.  I found the lazyaw configuration option and would
like to bounce some theories off the list.  It seems to me that once a server
has demonstrated that it will requeue a tempfailed message, there's not much
point in checking future tuples.  Even if the server is a spam source,
greylisting will not have an effect, so one might as well only whitelist the IP.
	I can only think of one scenario where enabling lazyaw would hurt.  If a
server behind a NAT firewall first passes greylisting requirements, gets on the
autowhitelist by IP alone via lazyaw, then another host behind the same firewall
begins spewing directly.  By experience, is this common?  What are the common
views on using lazyaw?  Am I right in assuming that lazyaw enabled will continue
to verify the tuple then, once requeued, whitelist only the sending server's IP?

Thanks in advance,

Jason
