The IMAP and POP server app provides a standard set of services for mail clients (Thunderbird, Mail, Evolution, Outlook/Express etc.) to connect to the server and retrieve email. If you are interested in running a lightweight mail server without calendar, web GUI, shared addresses etc., this app is required for users to fetch mail delivered to mailboxes by the SMTP server.

For a messaging and collaboration suite or a Microsoft Exchange[TM] drop-in replacement, please search the Marketplace for Zarafa Community and Zarafa Small Business Edition, respectively.
