I use two exclusively: http://www.mail-abuse.org and http://relays.osirusoft.com/ ..also, the http://relays.osirusoft.com/ site will give you a list of other available RBLs (there are MANY). I don't recommend ORBZ for two reasons: 1. they're (temporarily?) offline 2. they're a little too loose with the definition of a "relay", causing you to block perfectly valid mail.

That DNS idea is intriguing. We're looking at that problem right now, but I've got 20K+ people griping that they're getting spam. To put up firewall filters for every $@#%! smap host / sender is obviously not going to happen. I would love a better solution than filtering. -Shawn -----Original Message----- From: Jim Harrison [mailto:jim@xxxxxxxxxxxx] Sent: Tuesday, April 09, 2002 11:36 AM To: [ISAserver.org Discussion List] Subject: [isalist] Re: Any chance if using SMTP blacklists? http://www.ISAserver.org Does your mail server understand DNS lookups using those IP blacklist? That's really the best way to do it.
