URL rewriting thought

[Julian Y Koh <kohster () NORTHWESTERN EDU>]

This is total corner case consideration, but has anyone looked at the impact of these anti-phishing/spam URL rewriting 
products that will reformat URLs in emails to send them to a filtering service first on digital signatures?  Seems like 
you would invalidate the signature unless you somehow integrated the signature mechanism with the outgoing email 
rewriting, and you wouldn’t have any control at all over incoming email where your system is rewriting URLs.
