we're evaluating the zcs 7.1.1 (standard edition) and hope to control the access rights to certain distribution lists.
e.g. only few of our local users can send emails to the distribution lists (e.g. firstname.lastname@example.org)
i've found this can be done via the ancient postfix configuration, such as: RestrictPostfixRecipients - Zimbra :: Wiki
but from zcs 7.x product introduction, it looks like it can be done via the admin UI > Rights ??
can someone enlighten me on how to achieve this?
