I would like to setup Zimbra to be a backup mail server for our M$ Exchange.
I know this is easily achievable setting it up to forward all caught emails to exchange.
But this is only small part of what I want it to do. Basically, Zimbra will:
1. caught emails while Exchange is down
2. forward emails once exchange is up and running
3. allow all exchange users (basically, whoever has got an account in echange) to connect to webinterface of zimbra and check their emails
4. basically, zimbra will act as emergency backup mail server
So users with email accounts can logon to zimbra to check their emails while the exchange is down or is in maintenance mode or is beeing reinstalled. Once zimbra realizes the exchange is up and running it will forward alle mails back to exchange.
Is this possible with zimbra? Any ideas are appreciated.
