电子邮件表单不发送邮件

I'm trying to set up the contact form of my site. The script uses the template contact_me.php. The relevant excerpt of the form here:

// create email body and send it    
$to = 'jose.alberto.lara@gmail.com'; // PUT YOUR EMAIL ADDRESS HERE
$email_subject = "Contacto con Ecopolíticas:  $name"; // EDIT THE EMAIL SUBJECT LINE HERE
$email_body = "You have received a new message from your website's contact form.

"."Here 
are the details:

Name: $name

Phone: $phone

Email: 
$email_address

Message:
$message";
$headers = "From: noreply@ecopoliticas.com
";
$headers .= "Reply-To: $email_address"; 
mail($to,$email_subject,$email_body,$headers);
return true;

When I fill the form it seems to work; however, I don't receive any mail.

Remove the dot (.) in:

$headers .= "Reply-To: $email_address";

Everything with code is fine. You should know that function mail() won't send mail when it is run by local server. Here is proof: How to send an email using PHP?.

If you want to send mail even with local server you should use phpmailer.

EDIT: Also I think if you install hMailServer it will work on local server.

The command:

sudo apt-get install sendgmail

did the work. It was not installed in my server.
