I have a Virtualmin Pro server working fine with numerous domains.
I have another fancy new mail server that I plan to offer 'advanced messaging' service (Zimbra) for additional charge.
How can I route mail for certain users in a particular Virtualmin-hosted domain to the new mail server? I don't want to do the whole domain...that would be easy. This is probably an issue that all admins of large multi-server domains are familiar with. Unfortunately I'm not.
Am I wrong in assuming this is not something I should do with a simple forwarding in the user's configuration?
The fancy new mail server has its own spam filtering.
Thanks in advance,
