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.
As long as it’s compliant with Thunderbird, eg. using the same autoconfig at /mail/config-v1.1.xml, I’m happy.
I cannot imagine that it would support that. Android generally does not give its users root access…
