Simply prepending "@forwarder.com:" is quite less overhead compared to:

- encode to timestamp and the hash
- prepend the result
This is negligible, given that it can be computed in an interpreted
language in immeasurably small time. However, much of the overhead has
been moved into the SPF parser, which must now decide which address to
validate. Source routing is not common on the internet, and relying on it
will probably break things.
This protocol requires modification both on the forwarder
and on the original MTA.
The original MTA does not have to modify anything. SES is optional. But
without source routing SRS would be mandatory.
