Hi,
i am pretty new to postfix, i have set up a postfix sever that forwards mail over a relay host (gmail.com), which comes from another external server with fetchmail. That all works, but what i want to do is to forward only mail from certain sender adresses(whitelist). So where do i have to dig? The smptd_recipient_restrictions check sender_access doesn't seem to work. I am still getting all the mail Thanks toby
