Testing Environment

[jhotchkiss]

I would like to install the Zimbra VMWare Appliance on my VSphere 4.0 server. However, I need to know can I configure the Zimbra Appliance to work in parallel to our existing mail server. In otherwords, if I provide the same MX record DNS name with another email address as it's pointer, will I be able to receive mail on both servers? How would I configure this?

Thank you,
Jason Hotchkiss

Search the wiki (link at the top of this page) for the words 'split domain'.

Just as a data point, I did it differently (I did it before I found the wiki for split domains).

I set up zimbra as a subdomain. xx@yy.zz.com
I forward any mail for the accounts on the zimbra domain from xx@zz.com to the .yy.zz.com domain in the mailer setup.

I told zimbra to use the mailserver at zz.com as the outbound relay and I set up the mailserver at zz.com to rewrite any outbound yy.zz.com addresses as zz.com.

It looks ugly, but in all reality the zimbra config was 100% using the web interface and the mailserver at zz.com required one extra line in the config file for the rewrite.

I did it as I intend to only use the zimbra starter edition, and therefore I only want to have people who need mobile access or shared calendars on the zimbra server. The rest stay on the exim/qpopper/dovecot main mail server.
