Installing Zimbra with an existing Mail Server

[sbriscoe]

We have an existing network infrastructure with an imap/smtp mail server already up. We want to use Zimbra for the calendar collaboration for our employees. When I install, it requests a DNS MX record. Can we install Zimbra without it acting as the mail server?

We also have no LDAP

FYI: The FC4 version is being installed on our FC5, we're getting an LDAP error 256 on install

Two things.

- FC4 build runs on FC4 only. It won't work on FC5.

- Zimbra's calendar functionality uses email for invites, shares, and response. So it's not designed to work in a calendar mode only.

Well I installed Zimbra on FC4 and it was successful.

Is there any way to use our existing email server to forward all mail into the zimbra server?

We can log into the user side fine, but I can't figure out how to login to the admin side...the manual said to login as http://mailhost.example.com]:7071/zimbraAdmin Not working

The login to the Admin console is HTTPS not HTTP.

If you want to forward mail to a Zimbra server then you current set-up should have a 'smart host' or 'relay' facility for sending mail to an ISPs mail server (for instance), that's what you'd use to forward through Zimbra. If you want to convert to zimbra then imapsync is likely to be the tool you want, search the forums for some more info.

https://hostname:7071/zimbraAdmin/ isn't working either

Then you need to first check all the services are running, 'su - zimbra' then 'zmcontrol status' - if anything is stopped check the logs for info. If they're all running, are you trying to run the admin from another PC? If you are, try it on the zimbra server. If you still have problems is there any firewall or SElinux that may be causing the problem?
