[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.
