Post Office Protocol version 3 (POP3), an application layer protocol, is still one of most popular protocols used to access email messages at mail servers. After IMAP has been introduced, POP3 importance began to dwindle, due to the fact the protocol isn’t too convenient to use. POP3 doesn’t understand folders; it means the user has to either download messages locally, or use mail client-specific capabilities to sort the messages.

The more messages are in the inbox, the longer will it take to access them via POP3. Also, if messages are downloaded and erased, they won’t be ever available to other clients. POP3 in its basic form transmits user and password data as plain text; however, TLS and/or SSL can be used to handle this security problem.
