With regard to Gmail (google), I believe they use a properity storage system which compress data on their storage system. Not only does the same message not be saved twice for gmail customers, parts of message which are similar like attachments will not be stored twice. In reality if people used all their quota up, it doesn't actually use that much space on gmail systems.
