I am trying to migrate to Zimbra and am having some problems figuring out the split-domain stuff. I have read the wiki article on it but it doesn't address what I really want to do.

What I would really like if for all mail to be delivered to both systems with the Zimbra system being the primary. We currently use sendmail / POP3 that I manage. Is this setup possible?

Thanks for the help.

Thanks,
Ben
