Michal Čihař - DNS blacklists in Exim

DNS blacklists in Exim

Well I expected this would be more complicated than defining DNS blacklist servers list. Hower thanks to great defaults, all you need is to put list into user defines (separate file which is included early like /etc/exim4/conf.d/main/000_localdefs should be best place):

CHECK_RCPT_DOMAIN_DNSBLS = dnsbl.njabl.org : \
                            bl.spamcop.net : \
                            blackholes.five-ten-sg.com : \
                            cbl.abuseat.org : \
                            smtp.dnsbl.sorbs.net : \
                            spam.dnsbl.sorbs.net : \
                            zombie.dnsbl.sorbs.net : \
                            web.dnsbl.sorbs.net : \
                            rhsbl.sorbs.net : \
                            sbl-xbl.spamhaus.org : \
                            psbl.surriel.com : \
                            list.dsbl.org
