It is not my intention to hijack this thread, and to be honest it would be nice to see some statistics on the existence of duplicates, triplicates etc.
But when I create a duplicate of a message, it is often with the intention that I do not want to loose it and have a copy in a separate folder/mailbox. If then on the backend, on the server this is being undone, and there is a corruption on the storage at that specific area. I have still lost 'all' messages. So I am wondering if it is really worth doing this de-duplication?
