Greetings list.
I am activating the check through blacklists (RBL) for receipt of
mail, you can find many on the web, in fact place as a top 5, but
first he had not placed let emails come even as hotmail, yahoo, gmail,
among others. If it got to the final 2 below:
smtpd_recipient_restrictions =
...
...
reject_rbl_client sbl.spamhaus.org,
reject_rbl_client list.dsbl.org,
...
...
permit
My question is to see what I recommended for urls reject_rbl_client in
place, if you need more than that I have there? alone or with just
one?, what?
Thank you.

For my 5 user selfhosted email domain, I personally use the following
smtpd_recipient_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
reject_unauth_destination,
reject_invalid_hostname,
reject_non_fqdn_hostname,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unknown_sender_domain,
reject_unknown_recipient_domain,
reject_rbl_client bl.spamcop.net,
reject_rbl_client sbl-xbl.spamhaus.org,
reject_rbl_client dnsbl.njabl.org,
reject_rbl_client dnsbl-1.uceprotect.net,
reject_rbl_client dnsbl-2.uceprotect.net,
permit
I find that this does a damn good job at stopping 99.9% of spam.
Some people think that uceprotect.net are too reactive but I have not
had any issues so far.
