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

if(stristr(PHP_OS, 'win') === FALSE) {
$phpmailer->setFrom( $from_email, $from_name );
} else {
$phpmailer->setFrom( $from_email, $from_name, false );
}

This is marked as resolved on 4.6.1.
On WordPress 4.6 i've resolved this bug with this temporary fix:
open file [i]wp-includes/[b]pluggable.php[/b][/i]
search for line:
[code]$phpmailer->setFrom( $from_email, $from_name );[/code]
[b]replace with:[/b]
[code]if(stristr(PHP_OS, 'win') === FALSE) {
$phpmailer->setFrom( $from_email, $from_name );
} else {
$phpmailer->setFrom( $from_email, $from_name, false );
}[/code]
This is my temp fix on pluggable.php to get back working WP 4.6 email - on Win OS test server with Php 5.6.. and Apache 2.4, until WordPress 4.6.1 will be out.
