I would suggest three tests:

"am I (A|MX) for the domain" test for the stamp domain.

does the recipient address in the stamp match the smtp delivery address

a site wide double spending test.

the first test verifies that you are a legitimate recipient of e-mail 
for the stamp address/domain.  The second test further verifies the 
accuracy of the stamp held address.  The third test is the classic 
double spending test for serial and parallel double spending.

does this work for you?  I may just implement test number one for myself 
in camram.  :-)  although I really need a verify test and that's a bit 
more than I can dig into right now.
