After reading about how great K-9 was, I decided to give it a try. Mostly, it seems to be better than the default app on my Droid Inc. At least, it has a lot more options. One thing it doesn't seem to do, which the old app did, is to keep old emails around. It looks like if I delete the mail on the server (using POP3) from another mail client, K-9 will remove that mail from the Inbox folder. Does anyone know if there is a way to keep an old email from deleting itself if it's no longer on the mail server?
