Zimbra is fine and looks like making a big difference to my admin tasks.
Before it gets given to the users, I need to work out how to forward mail outside through an MTA.
I have a zimbra server called zimbra.xxx.co.uk (xxx to protect the innocent).
I want mail to seem like it's coming from xxx.co.uk, not zimbra.xxx.co.uk.
Do I need an external MTA for this for forwarding all mail?
If not, how do I change the local hostname so that email addresses and so on are sent out as email@example.com, rather than firstname.lastname@example.org
The hostname must be zimbra.xxx.xo.uk so that we can have an externally resolvable CNAME.
Interested to know if I'm close to the solution or far away
Thanks in advance
