Find all old e-mails from an expired domain

I registered an old domain and thanks to its e-mail... I managed to recover a twitter account.

I need to understand which other emails were activated on that domain (in addition to info @ domain). Maybe other services/socials are associated with other emails.

If I do a search on google with "@domain" it does not find anything because it considers "@" a wildcard. Is there a way / service to find all the indexed emails that were indexed somewhere for a domain?

Hmm very interesting method if You ask me.

About Your question, quick google search gave me this site: https://hunter.io/
It returned 6 emails from BHW domain. Give it a try.

Just setup your emailserver with a catch-all email from that domain.Sooner or later emails will roll in if the former owner didn't change anything.

Another option is to search archives like commoncrawl.org
