What are you trying to achieve by copying the email module to a new module? There may be a better approach you can take.
If you must take a copy, you will need to edit SendEmail.java so instead of importing emailtemplate.proxies.header it imports m02_02_qsm_email.proxies.header instead. That will allow you to pass in the Header from your module instead of the one from Email Template. You may find you need to make more changes though.
