I have the samsung vibrant. Using K-9 Mail. There is a check mark that we can apply in order to "show the Archive, Move, and Spam" buttons. I checked the box thinking that I could move my incoming mail into the correct box. I see that these boxes are grayed out and don't work. K-9 mail does not have a support site (at least I can't find one) to answer these questions. If anyone knows about any of the above I would appreciate any help.
