NANOG folk: Over the past few weeks, I have noticed an influx of SPAM(tm) transmitted by UUNet dynamic IP dial-up users (read: MSN, Earthlink, GTE, etc.) and relayed using Earthlink SMTP relays. Am I turning senile prematurely, or has anyone else noticed this influx? Also, how easy would it be for Earthlink and other nationwide "ISP's" (or more accurately, UU/PSI resellers) to do the following? This would not stop SPAM(tm) dead in its tracks, but I figure it would make it easier to hold spammers accountable at least... unless, of course, they use throw-away accounts, in which case there is not much that can be done... - institute anti-spam rules on their SMTP relays, i.e. only relay mail reporting to be from earthlink.net and the virtual domains they host - only allow SMTP relaying from IP's assigned to *their customers* dynamically (cross-reference Radius logs?) Constructive feedback would be greatly appreciated! Together, we CAN make a difference. Regards, Adam
