I just did a complete reinstall of OS X and had some troubles migrating my user so I've had to manually restore most of my files. For some reason Apple Mail is acting up a lot so I'm thinking about just resetting it to like "Default" settings and start again. I just copied the Mail folder at first and I don't think OS X liked that. I have an IMAP mail server so I can delete all the locally stored emails without a problem. Can I just completely nuke the "Mail" folder found in my Home Library? Or are there some files that I need to keep for proper functionality?
