    The only thing that bothers me about this app is that every time I change the notification settings to silent and uncheck vibrate, for some reason they go back to the original notification settings. This is so annoying I'm thinking about uninstalling.

    This works great with my LG Ally. If I send a picture with regular GMail, it takes forever or maybe not at all. With K9, it is immediate.

    My archive, move and spam buttons are grayed out How do I make them active? Other than that this is an awsome app.

    So I can decrypt my mail with the help of APG, but sending mail is a nightmare (aka doesn't work). In my opinion, being able to send and email from an email app is important, but that may just be me.. UPDATE: uninstalled... Got too fed up with the constant "failed to send" notifications

    Had to move from gmail and android default mail after they started their "conversations" nonsense.

    Works great with Gmail. Not so well with hotmail/live. Instead of deleting messages it will just mark them as read. Seems to be a common issue in most email clients.

    Forwarding emails simply starts a new email chain and doesn't include previous correspondence after last update.
