Hello all,

I'm new to Zimbra, being quite interested to it. I've read that Zimbra can distribute services on multi-server, but I don't know if I can do the following by Zimbra.

I was told to build two mail servers (IMAP), one for external use (connecting to the Internet) and the other one is internal. Authentication could be done either on two seperate LDAP servers or a single one. Those antivirus and anti-spam are crucial for the external one, but not necessary for the internal one.

What's intuitive to me (which seems stupid) is to install two Zimbras on these two mail servers. Anyone got better idea? Thanks in advance.
