Good point. Thanks for the explanation. But in my case, I ONLY bounce
outbound messages from authenticated users that cannot be delivered (due
to invalid domain name or domain down). So there's no risk in attaching
the message on the bounce since they are only going back to my own
authenticated users. I stopped bouncing entirely for inbound messages,
and am anxiously awaiting fastfail....
Thanks.

Hi,
I am curious, though, about your comment that sending the message
back as an attachment affects spam. I realize that including the
orig note increases the size of the bounce that needs to be sent.
But other than that, I don't see how it's going to help spammers be
more effective. Is it simply a bandwidth issue? Or am I missing
something else?
Yes, spammers could easily trick your server to send bounce messages
with their message attached. This way your server will effectively
become a spam sender and may also be blacklisted.
If the original message isn't attached to the bounce, it is worthless
for the spammer.
