My advice is to drop almost all RBL for REJECTING email and use them STRICTLY for "Greylisting" email. You can use even the most aggressive RBLs and have practically a zero false positive rate without doing any serious whitelist maintenance. This isn't precisely what you asked but as an ISP you really have no true idea what mail is tolerable for your users. While that argument COULD be made for greylisting the counter is that greylisting ONLY requires that the sender use a "real SMTP" server that 1) meets the normal requirements for retry OR 2) is NOT listed on major RBLs. We practically never reject email on a single criteria, but use RBLs, SpamAssassin, headers checks, etc to DRIVE greylisting. Those that pass greylisting may be rejected but ONLY if they fail on several of the other criteria. -- Herb Martin > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Steven B > Sent: Monday, March 13, 2006 2:46 PM > To: [email protected] > Subject: [exim] Most Lenient RBL implimentation? > > > I dropped most of the SORBS lists and have the following > still in place: > > sbl-xbl.spamhaus.org > list.dsbl.org > smtp.dnsbl.sorbs.net > relays.ordb.org > dnsbl.njabl.org > opm.blitzed.org > bl.spamcop.net > > Any comments appreciated. > > Steve > > > > > > > > > > > -- > ## List details at http://www.exim.org/mailman/listinfo/exim-users > ## Exim details at http://www.exim.org/ > ## Please use the Wiki with this list - http://www.exim.org/eximwiki/ > -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
