Mail Folder on Different Hard Drive

Hi all,

My original plan was to make two hard drives on a Mac Pro, one with just the system and one with all my working files. After reading about the random problems with moving the entire Users folder to another hard drive, I decided to do as much manually as possible without symlinks, etc. But I'm still left with the issue of what to do with my Apple Mail folder... Is there an easy way to move the location of the Apple Mail mailboxes and attachments (in /User/LIbrary/Mail or Mail Downloads) to another hard drive?

Thanks!
