Yahoo is always sending 250 on RCPT to, it only sends a response that the user does not exist after the DATA command, so basically, you would need to send the whole email to test yahoo. And since KnockMail is a GUI for https://github.com/syrusakbary/validate_email any code changes need to be made there.
