Everything You Need to Know About POP

The POP Internet standard supports receiving emails.

Post Office Protocol (POP) is an Internet standard that enables the download of e-mail messages from an e-mail server to a computer. POP has been updated twice since it started as POP1 in 1984. Post Office Protocol Version 2 (POP2) was released in 1985. Post Office Protocol Version 3 (POP3) was released in 1988 and included a new authentication mechanism and other work.

How POPs Work

Incoming email messages are stored on the POP server until you log in with your email client and download the messages to your computer. The POP standard does not provide a means to send messages. Simple Mail Transfer Protocol (SMTP) is used to send e-mail.

Comparison of POP and IMAP

POP and Internet Message Access Protocol (IMAP) are similar in that both are used to retrieve email. However, POP is older and only defines simple commands for retrieving email. IMAP enables synchronization between devices and online access. With POP, messages are stored and managed locally on your computer or device. So POPs are easier to implement and are generally more reliable and reliable.

Disadvantages of POP

POP is a limited protocol that allows email programs to download messages to only one computer or device, and has the option to keep a copy on a server for future download. POP allows email programs to track retrieved messages, but sometimes the process fails and messages can be downloaded again. POP also prevents multiple computers or devices from accessing the same email account and synchronizing tasks between them.
