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.

  • 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.
