We have a list, THURSDAY-SUPPER, which has "Send= Editor, Hold", and a number of editors and moderators. Spam mail was submitted to the list with a forged From address which was the list address. (Both From and To addresses were the list address.) Listserv requested confirmation from the moderators as usual. However, the moderation response was posted to the list: Your message dated Wed, 30 Sep 2009 23:21:34 -0400 (EDT) with subject ... has been submitted to the moderators of the THURSDAY-SUPPER list. That response was posted to the list immediately, without moderation being applied to it. I would have thought Listserv would never accept mail from the list address, either due to loop detection or some other rule. Is there a way to prevent that from happening in the future? We're running Listserv 15.0, but I hope there's a solution short of upgrading. Peter
