 * The string passed in will allow us to decide whether we have
 * a new message to be added or a row to be deleted.
 * Use the UIDL to find the proper row to update.
 * Note depending on the start of the string, the passed in string
 * will look quite different:
 * For TOP, it will contain the account name the data corresponds to
 * for DELE it will have the UIDL prefixed with the proper sequence number
