Hi again, what is your opinion for this configuration:
smtpd_client_restrictions = permit_mynetworks, permit_sasl_authenticated, check_client_access hash:/etc/postfix/access, # reject_unauth_pipelining, # reject_unknown_client, # reject_rbl_client sbl-xbl.spamhaus.org, reject_rbl_client zen.spamhaus.org, reject_rbl_client bl.spamcop.net, reject_rbl_client b.barracudacentral.org, reject_rbl_client combined.njabl.org, # reject_rbl_client rbl-plus.mail-abuse.org, # reject_rbl_client cbl.abuseat.org, # reject_rbl_client list.dsbl.org, # reject_rhsbl_sender dsn.rfc-ignorant.org, permit smtpd_helo_required = yes smtpd_helo_restrictions = permit_mynetworks, permit_sasl_authenticated, check_helo_access hash:/etc/postfix/access_helo, reject_invalid_hostname, # reject_unknown_hostname, reject_non_fqdn_hostname, # reject_unauth_pipelining, permit smtpd_sender_restrictions reject_non_fqdn_sender, permit_mynetworks, permit_sasl_authenticated, check_sender_access hash:/etc/postfix/access_sender, check_client_access cidr:/etc/postfix/access_client, reject_sender_login_mismatch, # reject_non_fqdn_sender, reject_unknown_sender_domain, # reject_unauth_pipelining, permit smtpd_recipient_restrictions = reject_non_fqdn_recipient, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, check_recipient_access hash:/etc/postfix/access_recipient, # check_policy_service unix:private/policy, reject_unknown_recipient_domain, # reject_non_fqdn_recipient, # reject_unauth_pipelining, permit smtpd_data_restrictions = reject_unauth_pipelining I changed the rules this way. Can you help me to tune them better? I would like to have different sections for client, sender and recipient restrictions as above. I need to tune these better.
