POP3 stands for Post Office Protocol (version 3), which comprise of mailboxes for email systems, such that users can regain email from a central location where email is stored. POP3 accounts allow the users to have mailboxes on a server with their domain name. It means that in case, you own the domain name; you can receive and send email at the personal address of website. Post Office Protocol Version 3 provides a simple and standard way for users for accessing mailboxes and download messages to their computers. |
Most of the e-mail applications (known as an e-mail client) make use the POP protocol and someone can use the newer IMAP (Internet Message Access Protocol). For setting up POP3 email, accounts for your domain, your domain must be hosted on server, which has nameservers.
POP3 allows a client computer for retrieval of Electronic Mail from a POP3 server through a TCP/IP (temporary) or other connection and it does not provide any option for sending mail, which is assumed to be done via SMTP or some other method. POP is useful for computer applications, e.g. mobile or home computers, without a permanent network connection which therefore requires a "post office" (the POP server) to hold their mail until they can retrieve it.
There are two versions of POP. The first level POP2 became a standard in the mid 1980's and requires SMTP to send messages. The newer version, POP3, can be used with or without SMTP.
