If someone sends a message to a list you subscribe to, as well as send you a CC on your private address. Or you subscribe to multiple lists and someone sends a message to more than one of them. In both cases you will receive multiple messages with identical Message-ID headers. > > >> If you send two identical emails (the same messege-id) to the same >> account, >then only the first one will show up in your inbox.
