Sure, but this is not as straightforward as it sounds. Let me explain. We use the Mailman mailing-list manager, which is really great and allows mail to news bidirectional gatewaying. However, there is a flaw in Mailman privacy options in this case: - either we allow anyone to post to the list, in which case undetected spam[1] goes to the newsgroup as well - either we only allow subscribers to post to the list, in which case Mailman wants to moderate posts coming from the newsgroup too Mailman is free software and can be patched; however, at the moment we lack the time to fix that. Google searches brought nothing useful; I will check with the Mailman maintainers whether a known solution requiring no coding is available or not. If we cannot find a solution in a reasonable time, we will suspend the service as mail spam is a real annoyance, especially when gatewayed to newsgroups. It would be a shame to be forced to do that as we have 58 people currently reading comp.lang.ada through this gateway.
