Ediscovery for only external contacts.

I want to search only for emails sent to any domain except my organization. I tried to use the following search conditions:
NOT to:mydomain.com
However, it does not return mail sent to both external and internal people. For example:
to: external@extdomain.com
cc: MyOwnMail@mydomain.com
This email won't be displayed in search and it was sent to external domain.
