I don't know about that. But it is possible to check whether an e-mail

Thats not a "chatmail" server, just connecting the the domain's MX
server and trying to see if the email is allowed to be sent there. If
the email is a correct email address, the domain's MX server should
allow it through.
But it opens another can of worms. What if the MX server is currently
down? What happens if it uses greylisting and initially will block an
incoming connection to reduce spam? This in my opinion is not the best
way of doing this.
