Mail is hosted by 1&1 Ionos. They gave the settings for IMAP and POP3. I used all the settings and the alternatives. IMAP won't authenticate when I initially set it up in Thunderbird. Thunderbird can't authenticate the password. Thunderbird can't automatically find the server settings. POP3 works just fine.
