storing email on external drive to save space
I am running out of space on my hard drive and have an external drive. I want to be able to store my emails on the external drive seamlessly. I want them to appear in mammal, but when I store them I want them to automatically go to the external drive. I also want to be able to manipulate them as I do now. I don't want a mirrored drive, though, as that will not alleviate my storage issues.
