Please see below my smtpd_recipient_restrictions. On my rbl client list I have multiple entries, but not sure how many of them actually maintained. Is there one single place where I can find such a list. Any help is greatly appreciated.
smtpd_helo_restrictions = permit_mynetworks, reject_non_fqdn_hostname, reject_invalid_hostname, permit smtpd_recipient_limit = 300 smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_invalid_hostname, reject_unauth_pipelining, reject_non_fqdn_sender, reject_unknown_sender_domain, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_rbl_client blackholes.easynet.nl, reject_rbl_client cbl.abuseat.org, reject_rbl_client proxies.blackholes.wirehub.net, reject_rbl_client bl.spamcop.net, reject_rbl_client sbl.spamhaus.org, reject_rbl_client dnsbl.njabl.org, reject_rbl_client list.dsbl.org, reject_rbl_client multihop.dsbl.org, permit ~LA
