无法连接到localhost上的邮件服务器

Question

I want to send email to entered email address. But I keep getting this error.

 mail(): Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set()

This is my code

    <?php
    $email=$_POST["email"];

      $message="Your application has been submitted tothe Incharge and Admin of the classes. Thanks for applying at our insitute.";

      mail($email,"Confirm Application", $message, "From: [e-mail]");
?>
      <form method="post">
        <input type="email" name="email" placeholder="enter your email address">
      </form>

What should I do to remove that error?

Answer 1

You cannot send emails from your localhost unless you have set-up some mail agent, I believe, you can get SMTP settings from email providers such as :

1. Mailgun . https://www.mailgun.com . - they provide 10k emails per month,
2. AWS SES - they have monthly free email plan,

You have to register a domain, even localhost will work to any of these and have to get the SMTP settings
