This could be simplified if smtpd daemons would log such information as number of send To's, Cc's and Bcc's. Counts, not all addressing would be a good alerting mechinism, a heads up to the admin to peek further for possible action. Then an administer could parse a logfile to determine possible spamming On Mon, 1 Apr 2002, Crispin Cowan wrote: [SNIP]
If there was a product that such large providers could deploy at their gateway that filtered *outgoing* mail, and the only thing it did was to bounce a copy of suspected outgoing spam back to the senders inbox, then a spammer's inbox would fill to bursting almost immediately, and the provider could lock out their account from sending any more mail until the issue was resolved.

I know: this requires very low margin providers to expend more effort, and we already know that they don't put much effort into spam fighting. This egress filter proposal is an attempt to minimize their effort required for effectivenss, and thus hopefully reduce their costs in dealing with spam cleanup efforts, e.g. the thousands of complaints that pour in after a large spam incident. Presumably some of the readers out there are in companies in the content filtering business. Consider this a product opportunity.
