Sorry, typo 11.0.15 is correct as per Release Notes, as long as it is not 11.0.11.
As I said before it is working fine on mine with Build #220.127.116.1103 with Java 11.0.15 - no need to add any workaround.
Is it recorded in the Ticket History that an attempt was made to send to CC/BCC recipient?
So the below fix does still apply, the version number in the config line needed to 12.7.8 even though we are running version 12.7.9 of WHD
The KB (https://support.solarwinds.com/SuccessCenter/s/article/WHD-12-7-8-no-longer-sends-emails-for-other-Techs-in-the-CC-BCC-fields?language=en_US) has been updated with 12.7.9 references. Its not fixed but you can make the workaround...work again.
