Such a shame This *used* to be great  however since May 2015  I've been unable to get ANY new email across any of my many email accounts - and as such have had to get accustomed to Google's main offering. I updated K-9 tonight  but it refuses every account I have  saying either the username and/or password is at fault  when none of them are incorrect. Result: Uninstalled.
