What is POP3?

POP3 (Post Office Protocol version 3) is a one-way incoming mail protocol that downloads a copy of messages from an email server to a local machine. Once the post office protocol completes the process, it deletes the original data from the server’s inbox.

However, many providers these days give an option to keep the original copies intact, allowing users to see the same content when accessing messages from a different platform.

In general, we recommend this setting for people who only use one device to access emails and want to view their messages offline. It’s also useful for those who want to free up an inbox space that almost exceeds its capacity.

Do keep in mind that this protocol cannot sync the content of your offline inbox with its online counterpart by default. So if the device that stores the messages is lost or broken, you could lose all of the ones you’ve saved.

Default Ports:

These are the ports that POP3 uses to establish a connection with an email server:

  • Port 110 – non-encrypted port
  • Port 995 – SSL/TLS port (also known as POP3S)
