The Perl SRS reference implementation implements this using bsddb
(or any database accessible from Perl). My Python pysrs
(http://bmsi.com/python/pysrs.html) also implements this using
bsddb by default, or any database with a Python interface.
The downside of DBBF is that the recipient often needs to extract
the original MAILFROM when evaluating the overall authenticity of
the message - which is easy to do with normal SRS or SES.
For instance, you need the original MAILFROM to query an
SES validation server.
I suppose the forwarder can record the original sender in an
RFC2822 header.
