Greetings,
You would need to add that group mailer (SecurityIT@domain.com) as a user within the dashboard and subscribe that user to those reports. If that is something that is not an option you can also setup inbox rules to forward a copy of the email you receive to your email (xyzname@domain.com) to the group mailer (SecurityIT@domain.com) if you're email client support that feature.
At this time there is not an option to add emails that are not associated with a user to receive reports/emails. A Feature Request has been logged.
