Hello everyone, 
 
My name is  Daniel and I am looking for a perfect backup solution for Mac email clients. I completely agree that Time Machine is the best option to backup on Mac but not for emails. I am more focused on emails, their attachments, address books and contacts. I want to only focus on email backup as my business is so. I run a couple of email clients, one is apple mail and other is outlook 2016 for mac. So is there any app like Time Machine that only focusses on Email Backup?
