Subject: How to allow email relay from anyone who have valid email address on the server
From: Russell \ (eliknettaxi.com)
Date: Sun Mar 26 2000 - 11:23:43 CST

Hello all.

        Here is the copy of my postconf configuration here. What the main problem
I have is that I want the postfix to allow the relaying of emails from users
that who have an account on the server but use the email client from other
network to send their emails along with recieving their emails. It seems
that it allows the emails to arrive at the servers for any domain names that
have the valid email address, but when it tries to send emails from the
untrusted clients though my email server, it rejects it due to the
reciepcient address being invalid.

        I been trying to find the right restrictions that allows the untrusted
clients to relay the emails if they have the valid email address and have an
account on the server to send emails. So..what exactly am I missing here to
allow myself to send emails using that email server? For example, a client
access the email server from Ozline Networks at home, and he want to
accesses the email over at mail.digi-host.com. He can recieves emails from
there, but when he tries to send email though there, it get rejected. How
do I open that one up? As for allowing which hosts it comes from, that I
have no idea on, since it is a web-hosting service, and I like to offer
emails service there. Plus, it also have virtual hosts there as well.
So...any help is appreciated there.
