This is rather difficult to do because it requires the MTA to start the filtering *before* reception is complete, which means the filtering process has to be able to complete processing before or by the end of reception. The only mechanism I know that is capable of this are rather complicated firewall rules that looks for and monitors connections to port 25. These tend to chew up a lot of resources on the firewall machine - especially during a spam storm. Most people just punt and use the RBL lists (I do). They have problems, but they do stop *a lot* of useless traffic. (Note that I use list.dsbl.org, sbl.spamhaus.org, dnsbl.njabl.org, bl.spamcop.net, and cbl.abuseat.org, and NOT sorbs! --Bruce
