Contact Form 7: wp_mail doesn’t work after update to 4.6

The solution has been found here – Make WordPress Core

I’ve made changes in wp-includes/pluggable.php on line 352 from

$phpmailer->setFrom( $from_email, $from_name ); 

to

$phpmailer->setFrom( $from_email, $from_name, false ); 

And it works! Thanks to Marius L. J. (Clorith)!
