Hi All,

I know many others may have asked the same question before and I may be repeating the question but even after going through wiki articles and various forum posts i am still unable to get the desired results.

Due to compliance reasons I need to implement this. My internal users cant send or receive mails to external domains. They can only send or receive mails to certain external domains and email ids based on business requirements.

Currently we are using Mdaemon and its quite easy to implement this restriction in it. But we have been planning to move to Zimbra for quite some time. since we have been unsuccessful to implement this requirement we are unable to migrate to ZCS.

I tried this wiki article Restrict users to certain domain - Zimbra :: Wiki but after implementing this it throws multiple errors.

Even internal mailing stops and throws ownership errors.

Hope I can receive some guidance from the experienced users in this forum.
