For those of us that own a domain with aliased email addresses, we should be able to add the entire domain to the dark web searches with supplied proof of ownership. I own d******n.com and frequently will add an alias to a new business I share my data with to track them (i.e., att@d******n.com, walmart@d******n.com) rather than having to add each alias (Iast check I had 100+ aliases)
