I currently only run one server with a junk folder (as far as I recall), and that is a "pending" folder for mail which has a challenge- response message sent out (not my choice, I'm just paid to do sysadmin work). > .

One problem with statistical anti-spam measures is users who blindly put their "spam" into it as training without review. So when (not if) a legitimate message is classified as spam the statistical system is trained to do that again... -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
