At the level of mod_python not easily. You might investigate:

   http://httpd.apache.org/docs/mod/core.html#errordocument
   http://httpd.apache.org/docs-2.0/mod/core.html#errordocument

Apache 1.3 and 2.0 as appropriate.

Only thing you could do at mod_python level for within your own code is 
use a
try/except block around stuff and catch any exceptions and formulate a 
different
response page that indicates the error. This can get messy with 
mod_python.publisher
as you need to drop back to coding in the style of basic content 
handler, accepting
req as an input parameter, setting req.status to an appropriate error 
code and
then raising an exception to indicate equivalent of apache.OK.

I'd rather not go into how to do that further as as I said it can get 
messy.
Using mod_python.publisher for simple stuff is okay, but when you need 
to go
into that level of customisation it can be a pain. Generally people run 
with
PythonDebug set to On during development and simply fix any problems. 
When all
is working okay, turn PythonDebug to Off and live with users getting a 
generic
Internal Server response as formatted by Apache. The error is still 
logged to
the Apache log file to assist you later in debugging even when 
PythonDebug
is set to Off.

You should be able to have form.html and form.py with "form.py/email" 
as form
action, but as I mentioned in prior email, MultiViews needs to be off. 
Ie.,
in configuration for that directory where mod_python.publisher being 
used
set:

   Options -MultiViews
