title: Php mail function won't work
body: <p>After researching several questions and try multiple options, I couldn't make it work still! </p>
  
  <p>I have this contact form that won't be sent.</p>
  
  <pre><code>&lt;form id="contact" method="post" action="process.php"&gt;
      &lt;fieldset&gt;  
  
          &lt;label for="name"&gt;Name:&lt;/label&gt;
          &lt;input type="text" name="name" placeholder="Your name" title="Your name" class="required"&gt;
  
          &lt;label for="email"&gt;E-mail:&lt;/label&gt;
          &lt;input type="email" name="email" placeholder="yourmail@domain.com" title="Your e-mail address" class="required email"&gt;
  
          &lt;label for="phone"&gt;Phone number:&lt;/label&gt;
          &lt;input type="tel" name="phone" placeholder="+34 111 22 33 44" title="Your phone number"&gt;
  
          &lt;p&gt;&amp;nbsp;&lt;/p&gt;
          &lt;input type="radio" name="rsvp" value="si"&gt;
          &lt;span class="destacar-contacto"&gt;ACCEPT&lt;/span&gt; the invitation&lt;br&gt;
          &lt;input type="radio" name="rsvp" value="no"&gt;
          &lt;span class="destacar-contacto"&gt;REJECT&lt;/span&gt; the invitation&lt;br&gt;
  
          &lt;p&gt;&amp;nbsp;&lt;/p&gt;
          &lt;p class="negrita-contacto"&gt;If you're coming: what would you like better?&lt;/p&gt;
          &lt;input type="radio" name="menu" value="carne"&gt; Calf sirloin with foie&lt;br&gt;
          &lt;input type="radio" name="menu" value="pescado"&gt; Marinade salmon with dill&lt;br&gt;
          &lt;input type="radio" name="menu" value="vegetariano"&gt; Fungus risotto&lt;br&gt;
  
          &lt;label for="mas"&gt;Is someone coming with you? Let us know their name and their prefered menu here:&lt;/label&gt;
          &lt;textarea name="mas"&gt;&lt;/textarea&gt;
  
          &lt;label for="message"&gt;Aditional message:&lt;/label&gt;
          &lt;textarea name="message"&gt;&lt;/textarea&gt;
  
          &lt;input type="submit" name="submit" class="boton" id="submit" value="Enviar" /&gt;
  
      &lt;/fieldset&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>And this is the PHP function: </p>
  
  <pre><code>$name = strip_tags($_POST['name']);
  $email = strip_tags($_POST['email']);
  $phone = strip_tags($_POST['phone']);
  $rsvp = strip_tags($_POST['rsvp']);
  $menu = strip_tags($_POST['menu']);
  $mas = strip_tags($_POST['mas']);
  $message = strip_tags($_POST['message']);
  
  mail( "formulario@ourdreamjourney.com", "rsvp",
  "Name: $name\nEmail: $email\nPhone: $phone\nRsvp: $rsvp\nMenu: $menu\nMas: $mas\nMessage: $message\n",
  "From: Our Dream Journey &lt;mail@hotmail.com&gt;" );
  </code></pre>
  
  <p>I tried randomly to send just "Name: $name" and I got an e-mail! But then put all the other options back and nothing again... </p>
  
  <p>Someone can help me please? </p>
  
  <p>Thank you so much in advance! :) </p>
