I agree, I was using K9 until FairMail came out. It has all the features from K-9, it is open source and from very reliable developer which I trust more than Mozilla with its fishy additions to firefox (author of NetGuard (https://github.com/M66B/NetGuard https://github.com/M66B/NetGuard ) which is the first software I install on any new phone. Firefox is the second, FairMail is the third). I can only wish all the software would be of this quality, congrats M66B.
