Zimbra as a Secondary Mail Server
Hi - I'm new to Zimbra, but have been eying it as a candidate to provide our small business with some great collaboration abilities. I'd like to leave our current mail server and mx record as is (because it is hosted and reliable), but I'd like to host a Zimbra server locally and pull mail from the 'primary' mail server into Zimbra for local distribution. I would plan for all employees to use Zimbra the vast majority of the time, but still have our 'primary' mail server in place in case the Zimbra server crashes or we lose Internet connectivity or other unforeseen issues.
I've searched the forums and Googled this, but have not found definitive information. The business I used to work for used Windows Small Business with Exchange and a pop3 connector to do essentially what I would like to do.
It appears that I could accomplish similar using fetchmail, but I am not a linux expert. Can anyone confirm that what I am trying to do is possible, and if it is, are there any good tutorials for this specifically or how to use fetchmail?
Thanks in advance,
