Dear All,
Is there any way to check both sender ip + sender address in postfix without using SASL Auth?
I would like to allow only from known IP + sender address for mail relay, e.g.
use...@test01.com + 192.168.1.1 OK
use...@test02.com + 192.168.2.2 OK
My current config is
mynetworks = /etc/postfix/allowRelay
smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/sender_checks, reject
But it will allow 192.168.1.1 to send mail using
use...@test02.com, how can I avoid this?
Best Regards,
Calvin
