Copy mail from one location to another, perhaps converting formats
The source mail is specified with the --source flag, and the destination with the --dest parameter. Both must be followed by a full path, which can end with a / to indicate that it is in Maildir format.
By default email is just coped, but the --delete flag can be given to have it moved instead.
