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.

  • For anyone who was using K-9 wondering why Thunderbird looks no different, it’s because they aren’t different.

    They build both apps from the exact same codebase. Only difference between the two are the default color scheme, the branding icons, and the text strings of the application’s name. It’s literally just a choice of which brand skin you prefer.

    Which, honestly, kinda cool. A virtually zero-cost way to keep a few K-9 stans happy.

        • No, autoconfig is a way for mail servers to tell clients the config they should use (ports, ssl/starttls, username, name/domain of the server, authentication for imap, pop and smtp). There are multiple standards by different mail client devs, eg. Thunderbird, K-9 Mail and some other check for autoconfig./mail/config-v1.1.xml and outlook etc. check for a “autodiscover” SRV record, or use autodiscover. or check /autodiscover/autodiscover.xml. As you see, it’s a mess. Well, only Outlooks “standard” is, as usually you wouldn’t care because M$ Winshit Crasher Server does that automatically, so they don’t care about good docs. Thunderbirds autoconfig is pretty well made and documented tho.
