Do you need to review important messages at a glance ? Search Folders lets you do just that. With this powerful feature you will be able to define virtual folders that will regroup e-mail messages based on certain criteria. 

Search folders do not create duplicates of your messages but rather lets you view them differently.

You can for example create a Search Folder that shows all the messages from "John" or another folder that creates all the messages coming from a Whitelisted source. 

The Search Folders will be available in your IMAP folders under the 'Labels' folder.

Since Search Folders is an IMAP level feature, this functionality is available in both your e-mail client and Webmail, wherever you are.
