Folks

Pretty new to Zimbra- please bear with me, it might be a newbie mistake...

Anyway just deployed the Zimbra appliance (v 7.1.1) and everything went as per instructions. Managed to setup a domain, create 2 accounts, all ok.

However mail is not flowing in or out of the server - i.e. it is being received ok (from external source) and submitted ok from the webmail but they stay in the deferred queue (no delivery to the mailbox or to sending to the outside world).

I guess I have messed up something but not quite sure where to start to diagnose this. As such any pointer / suggestion would be most welcome.
