Just switched from K-9 mail to Thunderbird mail on my phone. Migration process was very simple as Thunderbird has taken easily the backup of K-9. The one thing that still seems unclear : how did Thunderbird take this backup with all its passwords so easily?

@hansbrix is correct. It's the same app with a coat of paint. If you loved K-9 mail you'll love Thunderbird mobile. · 2 weeks ago
I am pretty sure the k-9 codebase just became the Thunderbird codebase, so the only change, was a logo and some patches. 😂 · 2 weeks ago
