Is there a way to get a list of all possible domains that could be used by MailJS?

My company uses MailJS in order to test sign ups with Playwright, and we receive internal alerts on every sign up (so sales can reach out if necessary). Is there a way to get a list of all possible domains that could be used by MailJS in order to manually filter out MailJS accounts from our internal notifications? I thought the /domains endpoint might do this, but it only returned one domain to me (and this domain has already changed during the course of our tests a couple times).

Thank you for any help you can provide!
