We cannot check yahoo emails via direct SMTP connection, so until today, we use a Yahoo API check to do this. However, it's flaky (see #1308), so we need a more robust solution.

Similarily to what's done with Hotmail, use a headless navigator to connect to yahoo's account recovery page https://login.yahoo.com/forgot to check if an email exists or not.
