Restrict some users to send only to their own domain

[mmenaz]

Hi, I've one installation where they have ony 3 "real" account (i.e. info@theirdomain.it) that fetche e-mail with pop3, and want to create i.e. other 10 accounts in zimbra to be able to use Calendar and exchange mails internally in the office.
They want to prevent the other accounts to be able to send mail outside zimbra (could be easily done by accident and without error, just and answer would never come back )
Is it possible and how? I've found something in wiki but looks about letting only some users send to a particular domain, that is not what I need.
Thanks

You'll want to do this: http://wiki.zimbra.com/index.php?tit...certain_domain

Oh, I sow it but concluded was not what I'm looking for... Now that I read more carefully yes, it's the answer! Thanks a lot!

I have followed the steps in the wiki as shown here Restrict users to certain domain - Zimbra :: Wiki several times now and when I get to the end of the settings and do zmmtactl start, the mta does a couple of things and then gives me about 8 warnings about files that are not owned by root and 6 more warnings about files not owned by zimbra. In order to edit the files postfix_recipient_restrictions.cf and zmmta.cf as the 'zimbra' user, I had to do chmod on those as sudo (running Ubuntu 8.04 LTS) and then su - zimbra to have permissions to change those files.

What am I missing? Sorry I am relatively new to Linux but am loving working with it. I followed the above mentioned wiki entry exactly (as best I could with the mentioned permissions problem) and it totally breaks all email sending on zimbra. I can't send any mail from any account to any account after doing that.

Thanks for any info.

I must have been commiting typographical errors somewhere each time that I was setting that up. I tried for the 5th time and it worked, even though I still got the warning messages.
Thanks.
