What do POP and SMTP stand for?
SMTP stands for Simple Mail Transfer Protocol, the computer language used to describe how mail is delivered from one Internet computer to another. When you send mail to an SMTP server (a computer somewhere on the Internet), that computer in turn sends the mail to the appropriate computer on the Internet. POP stands for Post Office Protocol, the language used by computers to describe how mail is retrieved by the user. If you have an e-mail account where you routinely pick up your mail, you probably do so through their POP server, though some online services maintain their own proprietary mail transfer system. Frequently, POP and SMTP servers are the same computer. Some ISPs (Internet Service Providers) use one server for receiving mail (POP Server) and another for sending mail (SMTP Server). support@mercuryd.com |
