[mod_python] "Not Found" message with Publisher example

Got the easy example workin fine from the Manual (3.2 section), but got hung up with the example that 
discusses how the Publisher works.  Edited the  .conf  file, created a new python script   mail.py, made a 
html form - but still get:

The requested URL /form/email was not found on this server.


I'm sure its a simple one - thanks for any thoughts !
