No, this is a seperate problem from spam messages left in the que. If it
were a spam message I'd just delete it, but a customer expects their mail to
be delivered (even if its a confirmation of failure). Yes, this only happens
with a very small %'age of mail but if your a dealing with thousands of mail
an hour is soon builds up.
The most common situations arise from customers mis-typing their reply-to
address. We accept the mail to relay but for whatever reason it fails to be
delivered and ends up frozen on the relay box with exim unable to send the
mail anywhere.
