Greetings everyone, I am coding an email verifier in Python, before sharing my code I would like to discuss my method with you guys.

I deducted that to check correctly an email we have to:
1.- Check if email is in valid format using Regular Expressions.
2.- Compare if the email host is listed on the blacklist of domains https://github.com/martenson/disposable-...klist.conf
3.- DNS check domain for a valid response in case they have a domain.
And last.
4.- Do a kind of SMTP send to receive a 250 response.

Anyone want to discuss this?

Email checker is the same as email verifier?
Im not sure about the difference? What do you want to check?

Email domains have a functionality, that allows "catch all". The implication of this is that all <insert>@domain.com emails regardless of the prefixed username that is sent to this specific domain it's server will return an accept back to the email sender to take the mail.

Spam traps are always catch-all, it makes them more effective traps.
