Thunderbird uses Server Settings for each email account you set up. They have changed the GUI over the years.

At mailbox name there is an v to open or fold the menu
v someone@someplace.wht

Server Settings
Copies and Folders
Composition & Addressing
Junk Settings
Disk Space
End-To-End Encryption (this is the actual message body, optional PGP etc)
Return Receipts

Click on Server Settings after opening the menu with v ir it was closed.

Server Settings
pop3 or imap for the mailbox, by Server Type.
Server name & port
User Name
Security Settings
Connection Security
Authentication method

Server Settings
[ ] Check for new messages at startup
[ ]
[ ]
[ ]
[ ] Leave messages on server



Message Storage


These settings exist on ANY desktop non-web mail client for each mail box.

Otherwise how would the program know where and how and how often to get email?

The GUI used to be far better, but mozilla has been slowly wrecking Firefox and Thunderbird.
