Problems with moderated and unmoderated groups on nonstandard setups
(Redirected from NSP configuration bug)Jump to navigation Jump to search
From Paul Schleck:
- At least one news service provider, Usenetserver.com, may cause problems for a newsgroup that is inconsistently listed among servers as both moderated and unmoderated. They will forward to the moderator submission address any post to a moderated newsgroup that reaches their server without an Approved header, even if it originated outside their domain. This is clearly inconsistent with established Usenet protocols and best practices, and will cause duplicate submissions, but I have been unable to get anyone at Usenetserver.com to acknowledge and act on this misconfiguration. Usenetserver.com resells its news service to private-label ISP's, so there is the potential for many, many origins of misformatted submissions causing duplicates. Over on rec.radio.amateur.moderated, we noticed this when we started getting duplicate submissions. Someone or something was reinjecting our articles without an Approved header, and they were getting mailed back to us. Procmail configuration allowed us to trap and report them, but it was still a hassle. We were finally able to reach someone at the ISP that was using Usenetserver.com as its NSP, and put a stop to the duplicates. See: http://groups.google.com/group/news.admin.net-abuse.policy/msg/a62e29151474aed2 but that only stopped them at this particular ISP. Another ISP could cause the same problem as the Usenetserver.com bug is still there.
