    Zimbra by default binds to all IP addresses on the server... so what is your problem?

    If this is behind a Firewall / NAT device then why don't you just forward the ports from each public IP address to the Zimbra server's single internal IP... And why would you need 5 different public IP addresses for the same server in the first place?

    As far as I know, your Linux machine will only make outbound connections from one of your NICs if it has multiple without bonding/teaming/aggregating, so you will definitely struggle with that on outbound emails if they need to come from each of those 5 IPs. I'm sure with NAT rules you could make the connections come from certain public IPs based on the destination if that's what you are trying to do. I'm with everyone else... Why?
