Push mail has not been working reliably for years, always leading to the error message "Syncing disabled" and tp delayed incoming mail. Why K-9 disables syncing remains unclear. Other email clients, like Thunderbird, do not have any such problem. K-9 also has too many, too complicated settings and some user interface problems. Apart from these problems it is good.
K-9 Mail is having trouble when OpenVPN connect is activated. All other apps and web sites work fine. Even when the VPN is then disconnected on LTE the problem persists. Moving next back to WiFi the problem still persists as well. Only a reboot of the phone seems to help.
Actually, it is a very good email app. The new icon totally sucks and the main developer seems to be completely deaf to users feedback about it. Don't be fooled by the icons you see on the Google play page for k9. It isn't showing the new icon. Even if the old icon doesn't come back, the icon needs a different look from what it is now.
I've been using this app for years, always steadily improving upon an already great app.... but what the heck is with the new icon?! Please, I join with many in asking "Please switch back to the old one!" [Edit] Still a great app, but the icon still hasn't been changed back. Looks like something K-9 actually threw up. When people complain about an icon enough that some are considering uninstalling what does that tell you? lol
Silly icon. Is all. I put it into an icon folder so I don't have to look at it the stupid fugly thing. Have you forgotten the derivation of "K9" ??? 5 stars again when common sense prevails. Notice how the dev(s) haven't issued any "replies" to the comments regarding the icon? Those that comment how we are luddites, go stare at the bottom of bucket. I do experience lots of issues with synch too, but I put that down to a rubbish mail server. In the final analysis, it's still an awesome app that is free with no nagging ads, so four solid stars.
K-9 mail still beats the pants off all the other mail clients for Android. As I use Thunderbird on my Linux notebook and Windows desktop, this is the closest thing to "Thunderbird on Android". My only issue is that it still doesn't support S/MIME. If you got that sorted, you'd be getting 5 stars.
