Don't bother with the ramdisk. disk is cheap and fast compared to smtp. OpenBSD spamd in front of a cluster of sendmail/postfix running boxes which have the valid list of recipients, and where the mail ends up (i.e. which exchange server[s]). Not hard to do, and scales almost infinetely. spamd box does greylisting and then round robins the smtp connections to a cluster of recieve/process boxes. Those boxes have the list of valid users, and if you want can do some sort of mail filtering/processing (i.e. spamassassin, clamav, etc. etc.) whatever gets through that is forwarded on to MmmSexChange. Fooling around with ramdisk/passthough stuff is more trouble than it is worth. -Bob
