Port: 110
Connection security: None
Authentication method: Normal password

How POP3 works vs. IMAP
POP3 downloads all mail to your computer and leaves a server copy for 30 days by default.
IMAP keeps everything on the server indefinitely but can fill your mailbox unless you delete mail regularly.
That’s all—your Thunderbird client is now set up to send and receive mail using POP3, with your server, ports, and authentication configured exactly as shown in the video.
