Preventing outside emails to an account

[borngunners]

Hi all

I have a special distribution list for all users in my organization. I want to prevent emails from outside to that distribution list. How do I go about doing that in zimbra. I don't see anywhere in Zimbra Admin to configure a distribution list to only accept emails from an internal account instead of an external account.

I know that it can be done with individual emails, but not with distribution lists.

ZCS 7.0.0, which is due out next week, is said to have a policy to set who can send to a distribution list. Maybe it's what you're looking for.
