How to convert IMAP mailbox into POP
Can I switch from IMAP to POP or set IMAP to delete from the server without deleting from the client?
I use POP so I can store all email locally and delete from the server after 100 days.
For some accounts, I also set up other clients to read email without deletion. This lets me receive mail on several devices with one working as the archive.
I cannot find a way to create the equivalent with IMAP and Thunderbird.
