IMAP

Introduction

By default, the Internet Message Access Protocol (IMAP) protocol works on Port 143 (unencrypted) or 993 (encrypted). IMAP allows online management of emails directly on the server and supports folder structures. Thus, it is a network protocol for the online management of emails on a remote server.
