Your disbelief has no relevance.  Yahoo does do it.

More to the point, I solved this problem for the Navy.  2.5 MILLION e- 
mail accounts, and they needed to stop accepting e-mail for accounts  
which didn't exist.

To put this in perspective, I did this on a 386/25 processor with 16  
megabytes of main memory in 1992.

It's not a hard problem, and *every* modern mail system handles this  
properly.
