That may be because compared to POP, IMAP is suitable for use in more than one, but on the server side mail storage space required large amounts of space per person is severely restricted in large systems, consumers quickly reached maximum capacity, would not receive. And because the IMAP itself has security protection, such as data encryption and password confidential, in conjunction with the SSL/TLS encryption protocol to encrypt all communication with IMAP and IMAPS (IMAP over SSL/TLS and IMAP4S) is called communication system is used. IMAPS 993-exploited, usually IMAP uses a TCP port 143.
