Dear All

I have searched everywhere but i cannot find any relative implementation or documentation for what i am trying to do .

We have our primary mail , dns , http server ( PLESK ) on the isp .
Our collaboration server is getting all the emails (Imap) and send the emails through the server above .
The collaboration server is not accesible from the internet directly but only through vpn tunnel .

So right now i want to replace the collaboration server with a new one which i want to install on it the Zimbra suite .

a) Zimbra suite is capable to work as the old collaboration server (sent , receive through the relay server ) ?

b) If yes how i can implement this ?

I look forward for your response .

Best regards ,

Michael
