does http://www.openbsd.org/cgi-bin/man.cgi?query=spamd fit the bill? spamd(8) in greylisting mode stopped 100% of my inbound spam that did not originate from legitimate mailservers (e.g. Yahoo, Hotmail, etc.; all the zombie-sourced spam was dropped before it ever even got to my mailserver); probably stopped about 99% of total inbound spam for me, all by itself. (it _would_ probably qualify as a proxy (and runs as part of pf(4)), so maybe it's not what you're looking for.) -- Scott Francis | darkuncle(at)darkuncle(dot)net | 0x5537F527 Less and less is done until non-action is achieved when nothing is done, nothing is left undone. -- the Tao of Sysadmin _______________________________________________ Discuss mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
