We have just released a new feature that allows you to manage your bounces directly on the Setup tab.  Previously this was a setting that required an Elastic Email Support Representative to do for you.  On the Setup tab there is a new check box you can set to have bounces return to the sender.  When this is not enabled we handle them ONLY in our Dashboard.  When it is checked we handle them in our Dashboard but we also return the bounce to the sender.  Finally, you can opt to provide an email address to deliver all bounces to if you have special processing.  AcyMailing users might find this feature useful.
