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.

          • Literally running into this problem. I have a microsoft account with shared calendar and just can’t seem to add it to the outlook app. It keeps trying to go to my domain. There’s a button to specify the provider, outlook, but it just won’t do it. Can’t tell what this closed source garbage is doing wrong, it shows the manual entry fields with my server’s info entered wrongfully.

  • Noob question:

    Is there any advantage over my phone’s stock email client, considering 99% of my emails are confirmation emails from online shops and similar stuff and I hardly ever actually send an email to anyone or receive one from an actual person anymore?
