	There is a negative to this kind of behaviour.

	FOSDEM is the principal Free/Open Source developers conference in 
Europe, and is hosted every year for a weekend in Brussels.  See 
<http://www.fosdem.org/> for more info.

	The FOSDEM mailing list is set up to silently discard messages 
from all non-subscribers, and no notice was sent out by the FOSDEM 
organizers months ago to this list when they were opening the rooms 
for reservations, although apparently they did have a private list of 
people who were contacted directly.  People are still asking on the 
list if there are rooms available, even though the members of this 
list were recently told that the rooms all filled up months ago.

	The reason they're still asking on the list?  Because they sent 
messages on this subject months ago which were simply discarded 
instead of being bounced, and they were never notified.

	No, you don't want to generate blowback to forged addresses.  But 
simply sending back a message saying that your post has been held for 
moderation is a form of blowback that is being generated today on 
most Mailman-hosted mailing lists.

	I don't see that it's any worse to send back a notice that your 
message was discarded or rejected.
