phpmailer显示 SMTP Error: Could not connect to SMTP host

phpmailer报错，使用QQ和163的可以，其他的就会报错 SMTP Error: Could not connect to SMTP host 如何解决？元素模板为您解答

在phpmailer 配置文件里面加上

public $SMTPOptions = ['ssl' => [

        'verify_peer' => false,

        'verify_peer_name' => false,

        'allow_self_signed' => true

    ]];

或者
 

$mail->SMTPOptions = array(

        'ssl' => array(

            'verify_peer' => false,

            'verify_peer_name' => false,

            'allow_self_signed' => true

        )

    );
