The Post Office Protocol, commonly known as POP, is an email protocol used to extract emails. POP downloads the emails from the server to the system and deletes the original ones from the server. This is done so that the users have access to the emails even during no internet connectivity. Mozilla Thunderbird uses POP as one of the email protocols.
