Downgrading to Open Source Edition: Multiple Domains?

Hello,

The marketing lingo on the Zimbra version comparison document is a bit ambiguous. I will be shutting down my ZCS Network Edition soon and would like to run the Open Source edition for my personal domains. Does the Open Source edition support multiple domains? I have two or three that I would like to host on one server with distinct mailboxes under each domain.

Thank you,
Chris
