Receiving masses of notifications

I had a week off and when I logged into my office pc I got hammered with dozens of notifications (including sound for each one). Obviously there must be a better way to handle this. Maybe bundle the notifications and/or turn sound off when there are many of them.
And it is of no real use anyway to receive more than 40 notifications when some messages are already a week old.
Another strange thing happened today, when I logged in at my PC and read and answered the messages of the last days. After a few minutes I suddenly received notifications for all messages I had already read on the same PC. Is this intended?
