The spam came from an MCI dialup (*.Atlanta.mci.net) and your machine has no anti-spam (anti-relay to be exact) rules. Get 8.9.1 and install it. It stops relaying by default. Do it quickly before this machine get into the RBL (http://maps.vix.com/rbl/). After you've installed it, forbid the dialup domains from the big companies (Compu$erve, AOL, MSN and so on) from reaching your machines directly. It won't stop them using other open relays but at least it will stop a few of them too stupid. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto@keltia.freenix.fr FreeBSD keltia.freenix.fr 3.0-CURRENT #62: Mon Jul 27 20:47:08 CEST 1998 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe security" in the body of the message
