Comment:

 I've added unit test to verify that when wp_cron has been called, that
 also From parameter of PHPMailer instance has been updated from its
 initial state. This update does not occur in cases when SERVER_NAME is not
 available and results in WP error messages and emails not being sent. This
 unit test is depending on #41485 as MockPHPMailer is not correctly reset
 and From parameter cannot be tested for changes from initial state.
