Im trying to figure out now for a few weeks here or there if i can install zimbra on one main site and use it with a few domains that arent on the same server?
For example maindomain.com installed zimbra on the VPS server. domain2.com is on another server with a different company. Can i still use the emails from domain2.com by checking in with 1 control panel online with zimbra?
2nd question... if we did collaboration on documents how do people check their accounts? Do they need an email account from my domain such as: email@example.com ? or can anyone with a @gmail.com or @yahoo.com collaborate if you invite them?
