Hi,
According to [1]: "Reject the request when $smtpd_sender_login_maps<http://www.postfix.org/postconf.5.html#smtpd_sender_login_maps>specifies an owner for the MAIL FROM address, but the client is not (SASL) logged in as that MAIL FROM address owner; or when the client is (SASL) logged in, but the client login name doesn't own the MAIL FROM address according to $smtpd_sender_login_maps<http://www.postfix.org/postconf.5.html#smtpd_sender_login_maps> ." with smtpd_delay_reject set to yes, where in my smtpd_recipient_restrictions I must put this restrictions to that it works properly? After permit_sasl_authenticated? That isn't clear for me. Thanks, [1] - http://www.postfix.org/postconf.5.html#reject_sender_login_mismatch -- Eduardo Júnior GNU/Linux user #423272 :wq
