You don't "hook" the default client - you replace it with your own.  You
need to alter the Registry to direct the "mailto" protocol to your own
program directly:

    (Default)="c:\path to\yourprog.exe "%1""

It is passed as a comand-line parameter to the program that is loaded to
handle the link.  The Registry value above contains a %1 as a placeholder
which the system replaces with the actual value.  Then, you simply write
your code to check if the program was started with command-line parameters
or not, and extract the value when needed.
