Ratings and reviews

Used to be great and I used to love it. But it's become increasingly unreliable in the last year. It drops messages (they're sitting in my inbox on other computers, but k9 never gets them), it doesn't synchronize the read and archived status to the server for hours, it has trouble sending emails, and sync never works (always disabled) It was a great open source project but I'm afraid I'll have to look elsewhere now. I appreciate all the work the community has put into the app, so long!

It's Trash now. I have 12 email accounts. Some business, some work, some personal. I enjoyed being able to see all inboxes on the main screen, with the number of new or flagged emails. This emulates Apples iOS Mail app. But they changed it. It was the ONLY REASON to use this app but the dev thinks the newer version is better. No, it's absolute trash now.

DO NOT INSTALL NEW VERSION WITHOUT RESEARCHING IT FIRST!!!!! You will regret it! UNINSTALLED 5.8 and rolled back to 5.6. !!!REALLY HAVE TO PUT THE NAVIGATION BAR BACK AT THE BOTTOM!!! And the LED color per account is missing! Using this for years, but I can't say that I like the next/previous message buttons on the top. Makes it extremely difficult for one handed users. Removing these features is not an improvement, nor an upgrade.
