Hi, I'm a bit confused between the
smtpd_recipient_restrictions <http://www.postfix.org/postconf.5.html#smtpd_recipient_restrictions> & smtpd_sender_restrictions I want to implement RBL on my mail server and I was thinking having the reject_rbl_client on the smtpd_sender_restrictions. If someone could clarify this to me it would be great. thanks
