It is not what happens in the real world. For sites handling significant mail volume, outbound mail and inbound mail are large enough and different enough in their ideal system design that it makes sense to have them handled by different systems. Spam has also spurred that split, since it is more important for most sites that inbound mail has spam filtering than outbound mail, and it is simplest to just push out mail through a system without such filters.
