Hello,
I have a problem, I have an external mail server and I need to make a local mail server that is to backup of the server external, and then with the same domain, so as to ensure a high availability.
So if the external mail server is down the local mail server is capable of sending and receiving mail, and synchronize with external mail server as soon as it returns.
Is there a solution with zimbra? I tried the fetchmail but it isn't a good solution for me.
I hope I was clear.
Thanks.
