Restrict Postfix Senders

[nwhit]

I have followed the article RestrictPostfixSenders - Zimbra :: Wiki and verified the settings several times and it doesn't appear to restrict the senders to local domain users. I want to make sure that any email that is relayed through the server, even from allowed IP addresses, are restricted to MAIL FROM one of our domains. After following the wiki article I can still send out from any email account:

[zimbra@mail ~]$ telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.

Any help?

I have this setup working in my network, more precisely 12 Zimbra servers, both open source and network edition but, I'll review the entire procedure to help you guys...

Guys, this procedure have some problems with the new versions of the Zimbra, me and my expert in Postfix's man are working to fix it immediatly.

Dear friends, the procedure is working.
Now I'm working to extend this feature to the open relay networks.

This procedure works in the Zimbra Open Source Edition 7?

I tried it, and even so I can send emails from any email address.

In zmmta.cf file, there are 2 lines with the same value

POSTCONF smtpd_sender_restrictions LOCAL postfix_sender_restrictions
POSTCONF smtpd_sender_restrictions FILE postfix_sender_restrictions

In my case, I delete the first line (line with "LOCAL") and it works.
Hope this help and good luck!
