Flexcan mailboxes

I'm getting confused by the FlexCAN documentation.  This is for a KE18F part.  The documentation says that there are 16 message buffers, but 64 mailboxes.  If I'm using the Rx FIFO, then message buffers 0-7 are not available.  The confusing part is that it seems to use the terms "Message Buffer", "Mailbox", and "MB" interchangeably.  What do mailboxes 17-64 represent then, and what are they used for?
