[Ubuntu] Zimbra Domain Name

[Gatt]

Just got a test Zimbra server installed but got a query

It has a hostname of mail-srv-1
and a domain name of internal.domain

but in the admin console (https://mail-srv-1.internal.domain) it shows the domain as..

@mail-srv-1.internal.domain

which is fine -except i want it @internal.domain like the rest of our network

how do I change Zimbra to read it as @internal.domain

I believe you can delete the domain and add the new one form admin, or reinstall using the domain name you want ( change settings on the final stage)

Thanks, managed to create the new domain and put the old one into "maintenance mode" but this also knocks out the system emails (spam, ham, admin, etc)
Can I just rename these then delete the domain name?
