Frequently Asked Questions

What does POP3 stand for?

Post Office Protocol 3, or POP3, is the most commonly used protocol for receiving email over the internet. This standard protocol, which most email servers and their clients support, is used to receive emails from a remote server and send to a local client. POP3 is a one-way client-server protocol in which email is received and held on the email server. The "3" refers to the third version of the original POP protocol.

Is POP3 still used?

While those limitations are substantial, POP3 is still a fast, robust protocol that is particularly useful if you only check email from one device. For example, if you only ever check mail from your PC using Windows Live Mail, then there’s no reason not to use POP3.
