[ILUG] Script to move Maildir content

[Rory Browne]

You might have trouble ssh-ing 60GB ( particularly if the servers
aren't beside each other ) , so it might be worth considering either
splitting the users up by first-letter-of-username, or creating a cpio
archive locally, and copy it to remote, and extract it in separate
steps. That way if one step fails, you only have to repeat that one
step. I'll talk more about that when I get some sleep in.
