Hello,
I have installed a RBL program in my postfix server. This RBL program responds IP queries like that: dig @localhost -p 53 213.176.163.216.std.rbl.servidor.midominio ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6 <<>> @localhost -p 53 213.176.163.216.std.rbl. servidor.midominio ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 37917 ;; flags: qr rd; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; WARNING: recursion requested but not available ;; QUESTION SECTION: ;213.176.163.216.std.rbl. servidor.midominio. IN A ;; ANSWER SECTION: 213.176.163.216.std.rbl. servidor.midominio. 0 IN A 127.0.0.2 ;; Query time: 79 msec ;; SERVER: 127.0.0.1#53(127.0.0.1) ;; WHEN: Mon Oct 15 14:30:44 2012 ;; MSG SIZE rcvd: 81 My server have two external DNS servers configured, so the Postfix program makes all queries to these two servers. I want to configure the Posftix server to check client IPs in my RBL program, so I've put this line in main.cf: smtpd_client_restrictions = reject_rbl_client black.rbl.servidor.midominio, permit But obviously the Postfix program makes all its queries to the external DNS servers, so my RBL program isn't used from the Postfix. I would like the Postfix program to use the external DNS servers for all the queries except for the RBL queries. Is it posible to configure that? Another posibility is to configure the external DNSs to delegate the RBLs queries to the RBLS program, but I would like to configure a direct communication between the Postfix program and the RBL program to have a better performance. Thanks!
