I have a problem with the default email client disappearing received emails. Just now, I saw two older mails in the inbox, then a few minutes later, a couple new spam messages arrived, and the others were gone! It appears that it clears the inbox whenever new mail arrives. This combined with the fact that it deletes the mail on the server (No option to disable this), makes for a big problem.. It may be that it only deletes mail that's been read already.. Not sure, need to test. Has anyone else noticed this, and found a way to prevent it?
