Ah, that explains it. Mailman has an option to turn on moderation messages, but we haven't enabled it. This policy is borrowed from a number of other mailman lists that also leave the moderation message disabled (for example, the GNU coreutils list behaves in the same way). I wonder whether a moderation message that replies to spammers could be exploited as a probe of "yes this is a valid list email address" (not that the spam would get moderated through, but it might make the moderator's life more time-consuming if it increases the volume of spam attempted). On the other hand, as a moderation reply message would only be sent to first-time posters, it won't be any change observable to current whitelisted addresses. What do other list readers think - should we turn on the moderation message that warns people when their message is being held? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
