如何从本地Wamp服务器和php

Question

我已经尝试了很多来自stackoverflow.com上的问题的解决方案，一切看起来都不错，但我仍然无法发送电子邮件

php.ini configuration

sendmail_path = "D:\wamp\sendmail\sendmail.exe -t -i"  // i check with both double and single slashes 
sendmail_path = "D:\\wamp\\sendmail\\sendmail.exe -t -i"
SMTP = localhost
smtp_port = 25 // tried with 465 port as well

php代码

$headers = 'MIME-Version: 1.0' . '\r\n';
$headers .= 'Content-type: text/html; charset=iso-8859-1' . '\r\n';
$headers .= 'From: humaaa@outlook.com' . '\r\n';
$rs = mail('iqra@gmail.com','subject','body message',$headers);
echo ($rs) ? "Success": "Fail";

使用PHPMailer tried with phpmailer class as well.

$m = new PHPMailer();  

$m->IsSMTP();
$m->Host = "my_domail.com";
$m->Port = "25";
$m->SMTPAuth = false;
$m->Username = 'humaa@my_domail.com';
$m->Username = 'xxxxxxxx';

$m->FromName = 'Huma';
$m->From = 'humaaa@outlook.com';
$m->AddAddress('iqra','iqra@gmail.com');
$m->Subject = 'This is PHPMailer test';
$m->Body = 'This is PHPMailer test here i am going to make you sure!';

$rs = $m->Send();
echo ($rs) ? "Success": "Fail";

我甚至尝试使用swift邮件程序，但仍然无法发送。我需要做什么？
