We are evaluating Zimbra, currently using Exchange 2003. I need to have Exchange and Zimbra running side by side, delivering email to both servers. This deployment is at a single location for a single domain. Any thoughts on how to accomplish this? I did find this in the wiki which is close. I know that by having this users sending from Zimbra will not see the sent email in exchange and visa versa but that is ok.
Thanks in advance.
