It has been awhile since I've seen these shared on the list, and I would like to hear what is still working. We have seen a sharp increase this past month in the number of spam that make it through our ISP's filter (Brightmail). Currently I have this in / etc/postfix/main.cf:

maps_rbl_domains = dnsbl.njabl.org,bl.spamcop.net,sbl- xbl.spamhaus.org

as well as:

smtpd_client_restrictions = reject_rbl_client relays.ordb.org

Are there others that I should add for even more effectiveness?

smtpd_recipient_restrictions =
permit_sasl_authenticated,
permit_mynetworks,
reject_unauth_destination,
reject_invalid_hostname,
reject_unauth_pipelining,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_rhsbl_client blackhole.securitysage.com,
reject_rhsbl_sender blackhole.securitysage.com,
reject_rbl_client relays.ordb.org,
reject_rbl_client blackholes.easynet.nl,
reject_rbl_client sbl-xbl.spamhaus.org,
reject_rbl_client opm.blitzed.org


+ I would recommend to implement greylisting.

Should these be listed under smtpd_client_restrictions or smtpd_recipient_restrictions? The Postfix site shows them under client and only the first three lines for recipient. I have seen elsewhere in other user's examples that they are combined. Is this an example of simply not being clear? Postfix.org has the following type of restrictions:

smtpd_recipient_restrictions
smtpd_client_restrictions
smtpd_sender_restricitons

yet in the example given above by Robert, he is using restrictions from all three, grouped under smtpd_recipient_restricitons. Doesn't that cause a failure?
