Just for a while (to make some tests) I want to use Zimbra only as an WEBMAIL, and more specifically, an webmail that is an IMAP client of another mail server.
So, is that possible to do that?
I have everything installed and running, I just don't know if I can do that.
How can I proceed?
It's not my intention to put Zimbra as my master server of everything before make tests with the most important (to me) resource: an IMAP webmail that reads/writes messages using a external MTA.
After the tests, if people approves the tool, I can make the huge changes.
