We also have |Loopcheck=Full but that did not prevent it. Though LISTSERV(R) is not bullet-proof, you're having a difficulty with one particular userid (and their mail system). This userid is best tracked down by observing these abstracted headers: Received: from rmx08.globecomm.net (rmx08.iname.net [165.251.8.85]) by klokan.sh.cvut.cz (8.8.8/8.8.8/Silicon Hill/Antispam/29.3.1998) with ESMTP id TAA10316 for <[log in to unmask]>; Fri, 12 Mar 1999 19:40:37 +0100 Received: from smv18.iname.net by rmx08.globecomm.net (8.9.1/8.8.0) with SMTP id NAA13897 ; Fri, 12 Mar 1999 13:40:07 -0500 (EST) Received: from listserv-mail.surfnet.nl (listserv-mail.surfnet.nl [192.87.5.141]) by smv18.iname.net (8.9.1a/8.9.1SMV) with ESMTP id NAA18581 for <[log in to unmask]>; Fri, 12 Mar 1999 13:39:50 -0500 (EST) As reported previously herein, look for userids@ globecomm.net iname.net and possibly [log in to unmask] Take appropriate action by NOT distributing individual emails (though possibly SETing them to DIGEST or INDEX, or even DELETE) the offending subscriber. /Pete
