✉️ For the 2nd time I gave #FairEmail a chance, but sorry, no... the setup and settings are so confusing and complex, I am really not able to use it (saying that as a geek is quite surprising, isn't it).
#K9mail remains the best free & opensource email client for #AndroidOS. It is the official #Thunderbird app for mobile. Thank you, #Mozilla @thunderbird https://k9mail.app/
