I am looking for a way to send to internal distribution lists from external addresses. I've found: RestrictPostfixRecipients - Zimbra :: Wiki
This, however, is not what we need. Currently we have this setup but it protects our firstname.lastname@example.org (which is a list containing everyone at the company) distribution list so that only certain people within our organization can send to it. What we need is a way to allow ANY address to send to ONE distribution list without interfering with any of our other restrictions. Any ideas?
