Hello
Recently I've been doing modifications to my internal server smtp
mail, so to authenticate e-mails that are sent
The authentication mechanism I used is explained in the postfix
site, very simple:
http://www.postfix.org/SASL_README.html # server_dovecot
All outgoing emails are delivered to a server that acts as mx
server and in turn this same server receives messages and delivers
them to the internal server with the new SASL authentication
mechanism.
My problem is the internal server rejects messages coming from the
server mx.

address rejected: Access denied (in reply to RCPT TO command))
So server 192.168.1.1 rejected the Sender address.
I was wondering if you can implement a white list in postfix, to
accept smtp connections from the IP address of my mx server without
any authentication.
Unless I'm misunderstanding something, wouldn't that circumvent the
authentication you just introduced?
Please post logs, postconf -n configs including the both servers.
When obfuscating please be consistent rather than too enthusiastic.

I have two mail servers, one is for the local network.
In this server, I configure the SASL authentication mechanism, so that
my users to send a message, their email client must authenticate.
The second server is a suffix, is in charge of sending messages from
the inner anterior to the Internet and vice versa.
Where is the problem?
When my external server (mx), receives messages from outside my
network, they must be delivered to my internal server and there is the
problem, reject the messages.
Asked in the previous post, if it was possible to leave out of this
mechanism between servers, the protocol would not authentication SMTP
for message delivery between servers??
