Mail::Checker seems to be unfit for Yahoo

It seems that it is impossible to test existence of yahoo mailbox without sending a test message. Yahoo seems to reject messages to non existing user in reply to "the final dot" in SMTP session.

I have tried to send message to non existing (long random) mailbox with the following result (bounce message):

<d5b980c9018f82c94cefee51193f8a61@yahoo.com>: host
