I would also expand this request to simply being able to search @domain.com
As an example, cPanel allows "catch all" so any errant emails are forwarded to a single account. It's intended so that a typo like bobb@domain.com can be redirected to bob@domain.com
You can use the feature to generate emails on the fly without them having an associated account, similar to the + syntax.
Unfortunately, that would also mean searching potentially hundreds of addresses one at a time to see if they've been compromised.
