Does _all_ mail to my domain come from the freebsd list (most of my incoming mail is freebsd-questions now, but still, I handle mail for ~ 50 domains, and I think there are just one or two people from these 50 domains on the freebsd list.

I'm stating (as a fact, not "claiming") that the DUL (and the rbl) stop a _lot_ of spam which would otherwise be in my user's mailboxes. Whenever some spam slips through this, I just drop that address into my local blacklist (and perhaps file an rbl nomination). > DUL and RBL are simple-minded solutions to a complex problem.

"Real Work" more often than not produces some totally rube goldberg solution which doesn't scale too well (take a look at http://razor.sourceforge.net for example ...) Look ... this is becoming way OT for freebsd-questions, so would you mind taking this to news.admin.net-abuse.email please? I'll answer further questions there. --suresh -- Suresh Ramasubramanian + suresh@oyeindia.com Sysadmin, OyeIndia.Com + http://oyeindia.com You do not have mail.
