my foaf harvester turns every email address into a hash and uses
these for matches. There are plenty of online converters and code for
doing this, e.g.

Morten Frederiksen's online converter
http://xml.mfd-consult.dk/foaf/sha1ify/

in the context of foaf, an online converter by Leigh Dodds:
http://www.ldodds.com/foaf/foaf-a-matic.html

I found some snippets of code that also do this:

Java
http://www.w3.org/2001/sw/Europe/200303/geo/JavaSha1.java

Perl
http://www.w3.org/2001/sw/Europe/200303/geo/PerlSha1.pl

These all hash the mailto: part as well as the actual mail address.
