AstaroOS: MSP-style multi-tenant for Web and Mail
Ability to multi-tenant the main features (web proxy and email).
I assume he has multiple domains, and wants different mail admins to only see their domain.
So we clearly understand the request, can you please provide more information? Specifically on what you feel is lacking now; both the Web and Mail have profile-based configuration which can be used to create totally separate ways of filtering mail and web. What is needed?
