Let's say I sort all my mail from a mailing list to one folder, and all my mail from friends to another. If I get a message from my friend sent to both me and the folder, I would like for it to show up in both folders.
Instead of using separate mailboxes (there is no such thing as "folder" in IMAP), perhaps you may want to use IMAP keywords?
