Este es el código que tengo funcionando; sin embargo, quiero incorporar una forma de tener una autenticación smtp usando mi cuenta de gmail, pero no puedo entenderlo ... ¿me ayuda?

<?php

if(isset($_POST[''email''])) {

    $email_to = "[email protected]";
    $email_subject = "Website Inquire";


    function died($error) {
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }

    // validation expected data exists
    if(!isset($_POST[''first_name'']) ||

    }

    $first_name = $_POST[''first_name'']; // required
    $last_name = $_POST[''last_name'']; // required
    $email_from = $_POST[''email'']; // required
    $telephone = $_POST[''telephone'']; // not required
    $comments = $_POST[''comments'']; // required

    $error_message = "";
    $email_exp = "/^[^0-9][A-z0-9_]+([.][A-z0-9_]+)*[@][A-z0-9_]+([.][A-z0-9_]+)*[.][A-z]{2,4}$/";
  if (preg_match($email_exp, $email_from)) {
    echo "Email address is valid.";
  }
  else 

    {
        echo "Email address is <u>not</u> valid.";
  }
    $string_exp = "/^[a-zA-Z .''-]+$/";
  if(!preg_match($string_exp,$first_name)) {

    died($error_message);
  }
    $email_message = "Form details below./n/n";

    function clean_string($string) {
      $bad = array("content-type","bcc:","to:","cc:","href");
      return str_replace($bad,"",$string);
    }

    $email_message .= "First Name: ".clean_string($first_name)."/n";

    $email_message .= "Telephone: ".clean_string($telephone)."/n";
    $email_message .= "Comments: ".clean_string($comments)."/n";



$headers = ''From: ''.$email_from."/n".
''Reply-To: ''.$email_from."/n".
''X-Mailer: PHP/''.phpversion();

@mail($email_to, $email_subject, $email_message, $headers);

}

This is a complete working example.    
<?php
    // this is for troubleshooting errors 
    // set the 1 to 0 to turn off (must set to 0 when in production mode or when you run this live 
    error_reporting(E_ALL);
    ini_set(''display_errors'', ''1'');
?><?php
    if(isset($_POST[''email''])) {
        $email_to       = $_POST[''email''];
        $email_subject  = "E-mail from website visitor.";

        // try adding a useful/relevent message to errors output to users
        function died($error) {
            echo "We are very sorry, but there were error(s) found with the form you submitted:/n/t ";
            echo $error."<br /><br />";
            echo "Please go back and fix these errors.<br /><br />";
            die();
        }

        // validation expected data exists
        // since all post are submit, check if they are empty or equal to an empty string
        if(isset($_POST[''email''])){
            if($_POST[''email''] == "" || $_POST[''first_name''] == "" || $_POST[''last_name''] == "" || $_POST[''telephone''] == "" || $_POST[''comments''] == ""){
                died(''Please fill out the entire form'');
            }

        $email_from = $_POST[''email'']; // required
        $telephone  = $_POST[''telephone'']; // not required
        $comments   = $_POST[''comments'']; // required

        $error_message = "";
        $email_exp = ''/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+/.[A-Za-z]{2,4}$/'';

        if(strlen($comments) < 2)

        if(strlen($error_message) > 0)
            died($error_message);
        $email_message = "Form details below./n/n";

        function clean_string($string) {

Desea utilizar una biblioteca de correo PHP moderna, como SwiftMailer que admite la autenticación SMTP.

Consulte las instrucciones de Google sobre qué servidores usar y los documentos de SwiftMailer sobre el envío de correo a un servidor SSL / TLS SMTP y el envío de correo con un combo de nombre de usuario / contraseña .

Al actualizar su código para usar SwiftMailer, debe deshacerse de esa abominación de una expresión regular de validación de correo electrónico, excluyendo numerosas partes y dominios locales completamente válidos. La corrección de cordura que se impone al construir el mensaje usando llamadas de método va a ocuparse de la mayoría de los otros problemas potenciales en tu código, como esa extraña función clean_string ; no la necesitarás (y no estoy seguro de qué crees que lo hace aquí, pero en realidad no hace que la cuerda sea más segura).

Puede usar PHPMailer http://sourceforge.net/projects/phpmailer/ , así es como envía correos electrónicos usando GMail, pero HTML y CSS no lo ayudarán mucho aquí.

function email($to, $subject, $body){
    require_once("class.phpmailer.php");

    $mail = new PHPMailer();

    $mail->SMTPAuth = true;
    $mail->SMTPSecure = "ssl";
    $mail->Host = "smtp.gmail.com";
    $mail->Port = 465;
    $mail->Username = "name@example";
    $mail->Password = "123456";

    $mail->SetFrom("[email protected]", "Name Example");

    $mail->Subject = $subject;
    $mail->Body = $body;

    $mail->AddAddress($to);
    $mail->Send();
    unset($mail);
}

Creo que usando Gmail; google cambiar los métodos de autenticación allí, pude autenticar con éxito siguiendo este paso primero: Video link esto es para el proceso de 2 pasos para permitir la aplicación externa

Necesitará generar una contraseña de aplicación.

luego use esa contraseña para su aplicación PHP.
