Thunderbird: POP3 Configuration

PLEASE READ: Important information regarding “POP3”:

“POP3” by default downloads email from a server to a single computer or device, then deletes it from the server. Because your messages get downloaded to a single computer or device and then deleted from the server, it can appear that mail is missing or disappearing from your Inbox if you try to check your mail from a different computer or device.

It is highly recommended that both parts of this article are followed to ensure a copy of the message is left on the server. This will need to be done on each computer or device you setup via "POP3".
