Hi,

I have a Zimbra server Version 7, with 300 accounts from which I need to convert 50 of them to internal mail service maintaining the same domain they already have (i.e., all 300 accounts will have the same domain but 50 of them will have restrictions).

I have the solution for restricting the outbound mail but I also really need the restriction for the inbound mail from outside the domain for those restricted accounts (InternalAccounts@domain.com).

Here is an example:

# Solution I have implemented right now (Solution WIKI ZIMBRA):
InternalAddresses@domain.com - DO receive from the Internet and DO NOT send mail to the Internet (DO receive and send to AllAcccounts@domain.com)
allTheRest@domain.com - Receive and send to anywhere.

# This is what I need:
InternalAddresses@domain.com - DO NOT receive NOR send mail to and from the Internet (DO receive and send to AllAcccounts@domain.com)
allTheRest@domain.com - Receive and send to anywhere.

That is to say that I only need to resolve that the internal accounts DO NOT receive from the Internet, in this way the InternalAccounts@domain.com will stay exclusively as internal mailboxes.

Best regards to all and I appreciate any advise or help you can give me.
