How to get a list of public emails associated with a given domain?

Question

Google

There is a domain, let's call it domain.com. How can I formulate a request to Google or other search engines so that all emails of the form [email protected] are found.
Well, or at least is there a ready-made script that goes to www.domain.com, scans all pages for emails.
Thank you.

cunning how
everything like this is illegal, "on the domain itself" what can you find, if the domain is a modern
hunter and the like get it from onion databases, hiding behind the legitimacy of crawlers

Answer 3

There is no such way.
Because I can do whatever I want with mail. For example, I can send a fictitious message "User not found", and the letter will be delivered :) And everyone who needs to know this :) And who doesn't need to - get a whack. I can accept mail to fictitious addresses - and drop it right there - just so as not to load the mailer with unnecessary thrashings.
