I try to get mail from an external account, I found, in each user configuration (Preferences -> Account) this feature, but our user usually use client application to read mail (like thunderbird) and this feature does not work.

I see in this post that zimbra use a pop 3 connector

But I don't found where I can configurate this connector.

Thanks,
Massimo
