Php Amazon EC2实例邮件在bitnami服务器中不工作

我已经安装了用php脚本发送的邮件，但没有收到任何邮件

• sudo-apt-get-install-sendmail

---

• 同时重新启动并重新启动EC2服务器

这段代码在另一台服务器上工作，但在Amzon ec2上不工作它在Amazon ec2上的工作方式

<?php
/*
 * Enable error reporting
 */
ini_set( 'display_errors', 1 );
error_reporting( E_ALL );

/*
 * Setup email addresses and change it to your own
 */
$from = "dhokaijaydeep@yahoo.com";
$to = "dhokaijaydeep@gmail.com";
$subject = "Simple test for mail function";
$message = "This is a test to check if php mail function sends out the email";
$headers = "From:" . $from;

 // $headers = 'From:'.$from.'<' . $from . '>' . "\r\n"; message: 
// $message = "This is a test to check if php mail function sends out the email. \n\r";


/*
 * Test php mail function to see if it returns "true" or "false"
 * Remember that if mail returns true does not guarantee
 * that you will also receive the email
 */
if(mail($to,$subject,$message, $headers))
{
    echo "Test email send.";
} 
else 
{
    echo "Failed to send.";
}
?>

安装sendmail后，您是否重新启动了服务器？请检查您的

php.ini

，sendmail处于启用状态或不启用状态，然后重新启动并重新启动EC2服务器。如何检查php.ini中的邮件功能启用
