Mozilla Thunderbird for Android is now available in beta, built upon the K-9 Mail app.
The beta includes core email features like account setup, email organization, and notifications, with feedback encouraged from users.
Thunderbird for Android will remain a separate app from K-9 Mail, requiring users to migrate if they previously used K-9.
Oh right, that’s a server URL path, I thought it was just some config file one would have on their Linux host.
And this says that K-9 supports the same autoconfig as Thunderbird, so presumably the rebranded app would, too: https://forum.k9mail.app/t/autodiscover-autoconfig/7118
