It appears to be an email client vulnerability where inlined HTML  
causes code (I assume JavaScript) to be executed; this code reportedly  
makes the email client send a cleartext message back if the email  
client parses and displays remote HTML. If so, turning off the option  
to display remote HTML code should suffice.
