The Python, Perl, or C (libspf or libspf-alt) libraries all transform
a sender to an SRS sender and vice versa.  If your application is 
already generating an email, it is trivial to add the header.
Finding the header in an rfc822 attachment is pretty trivial with the Python
email library - don't know about Perl or C.  I think Javamail is not
too bad either.  (What is your application written in?)

But then, those Windows SMTP "events" sound a lot like sendmail milters -
and would be a pretty flexible way to go.
