send email twice to the same email address

[haipeng du]

I try to use mail context to send email:
this.getMailetContext().sendMail(mail.getSender(), emailAddress,
                                                 mail.getMessage(),
MY_FORWARD_PROCESSOR);
mail.getMessage().setSubject("Changed subject");
this.getMailetContext().sendMail(mail.getSender(),
this.jobApplyAdminAddress,
                                                 mail.getMessage(),
JobApplyProcessingConfigContext.FORWARD_PROCESSOR);

 it will only send mail one time.
What kind of stuff I missed?
Thanks.
