Can zimbra use other email servers (Imap, pop)?
I've just been taking a look at zimbra, and I like the centralised server arrangement, unification between the email client, address book, calendar and others through zimlets.
We here in the house who want to collaborate already have several email accounts, which we all check in our existing mail clients. From looking at the documentation it seems that the zimbra ajax mail client will only talk to the zimbra server. Is it possible to use zimbra without running an MTA, and somehow use zimbra to collect mail from other accounts, while still using all the other zimbra features?
