Restrict Postfix Recipients

[kaushik209]

Hi
I was looking for some process I can restrict senders to send mails to some distribution list except allowed ones. I found this link
RestrictPostfixRecipients - Zimbra :: Wiki

I am using zimbra 5.0.2
Release 5.0.2_GA_1975.RHEL5_20080130221917 RHEL5 FOSS edition

The steps mentioned in the wiki is not working. Whenever I follow the steps zimbra stops sending mails shows "451 4.3.5 Server configuration error"
Any suggestions how to make the restriction happen.

Thank you in anticipation

The wiki article does work, you probably have made some error - recheck your implementation of those instructions. You could also search the forums for some further details.

Thanks Bill......but I have done it 8 times..checked every line...............I have then implemented it on another zimbra...but the results are same.

Well, it works for other people on the forums. You'd better post some more information about what, exactly, you've done including examples and some further details from the log files.

Well..firstly I created /opt/zimbra/postfix/conf/permitted_senders and made below entry
localhost OK
abc.com OK
zimbra.abc.com OK

Then I created /opt/zimbra/postfix/conf/protected_recipients and made below entries
xyz@abc.com permitted_senders_list

Then I made a bash script in /opt/zimbra/postfix/conf/update_protected_recipients with below entries
#!/bin/bash
echo "rebuild permitted_senders"
postmap /opt/zimbra/postfix/conf/permitted_senders
echo "rebuild protected_recipients"
postmap /opt/zimbra/postfix/conf/protected_recipients

And made this script executable by chmod 755
and executed which made two files under /opt/zimbra/postfix/conf
1)permitted_recipients.db
2)protected_recipients.db

Then I made below entries in /opt/zimbra/conf/main.cf
permitted_senders_list = check_sender_access hash:/opt/zimbra/postfix/conf/permitted_senders, reject
smtpd_restriction_classes = permitted_senders_list

Then edited /opt/zimbra/conf/postfix_recipient_restrictions.cf and made first line entry
check_recipient_access hash:/opt/zimbra/postfix/conf/protected_recipients

Then I restarted postfix by
postfix reload

After this I tried to send mail from webmail of any user of abc.com to the distribution list but everytime it showed one error msg of

"The following recipient(s) cannot be reached:

'xyz@abc.com' on 22/09/2009 10:34 AM

451 4.3.5 Server configuration error"
Please check If i have done anything wrong.

Sep 22 03:30:26 zimbraxxx postfix/smtp[8059]: 5A2B414A50CD: to=<xyz@abc.com>, relay=zimbrax.abc.com[xxx.xxx.xxx.xxx]:25, delay=73490, delays=73489/0.96/0.05/0.04, dsn=4.3.5, status=deferred (host zimbrax.abc.com[xxx.xxx.xxx.xxx] said: 451 4.3.5 Server configuration error (in reply to RCPT TO command))

This is what I received from logs

In version 6 is this the only way to do this? It's not possible to limit the senders within the UI?

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...

[Thiago Camargo Martins]

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.
