We were missing the possibility to add carbon copy (CC) recipients to emails sent via DSpace's Email class.
I created a pull request ( https://github.com/DSpace/DSpace/pull/1748 ) that does:
- add addCarbonCopyRecipient(String email) to the Email class analogous to addRecipient(String email)
- add javadoc comment for addCarbonCopyRecipient(String email)
- add CC recipients to actual email
Are you interested in integrating this functionality?
