[Mailman-Developers] Any other NNTP gatewayers out there? SMTP reject bounce processing is broken?

	I was doing that for comp.protocols.time.ntp for ntp.org 
(gatewayed to questions at ntp.org).

	I imagine this is because digest mode results in stripping out 
the problematic headers that would cause Exim to barf on the message. 
Since the digest version of the message is sanitized, the digests get 
through okay, while the unsanitized version of the message is

	We were using postfix, not exim.  I don't recall running into any 
problems with the gatewaying which were a result from postfix 
rejecting messages, however.

	I do recall reporting problems whereby we tried to set up the 
list as "closed" (so that only subscribers could post), and mailman 
made the mistake of applying this action to incoming NNTP messages as 
well as incoming SMTP messages, resulting in moderation notices being 
sent to anyone who posted via NNTP from an address that was not 
subscribed to the list.

	As such, we were forced to turn off this feature.  It would be 
nice if there was a way to get mailman to apply certain features to 
messages only coming in via one of these mechanisms.  For example, I 
would still like to apply the anti-spam methods and MIME format 
stripping methods to messages coming in via both SMTP and NNTP, but 
I'd like to be able to apply the posting restrictions only to 
messages coming in via SMTP.
