I am very glad that we now have an alternative to the pre-installed email app. It does work for many of the
problem email addresses that do not seem to connect with the pre-installed app. However, I only know from personal experience that it has worked with comcast and Cox and AOL, which always seem to have
problems on the native email app. Anybody else have 'miracle stories' to report? Or problems? with K9.
F.Y.I. - here is the user group for K9 https://groups.google.com/forum/?fromgroups#!forum/k-9-mail
I use K-9 on my android phone and N7, and it works really well for IMAP accounts without causing battery drain.
