Wietse, thanks for the quick response, and a solution that looks like it
might work. That wouldn't also suppress 5xx bounce notifications, would
it? In order to be good e-mail citizens we have to capture those
undeliverable addresses and remove them from our active mail database.
I'm assuming that the line time after which the sender receives the
message headers of mail that is still queued implies that hard bounces
would be removed from the queue and we would still get the bounce
notification.
Thanks again for your help.

Paul:
I was
asked to config the outbound mail servers to quit returning deferred
message delivery notifications back to our mail server but I'm not
really seeing way to do that.
The simplest option is to set delay_warning_time=0.

Changing this takes effect only for new mail.
