cant send email headers
<p>I am unable to send email address carried from email box in html form.
when i fill up the form email box with someone@yahoo.com the email is send to the mailbox
but when i fill the form email box with someon@gmail.com the email script works but the email doesn't come in the mailbox or the spam folder. </p>

<pre><code>-----*This is the html code*-------

&lt;input type="email" name="email" id="email" size="70" /&gt;&lt;/td&gt;

-----*-------------

$email_from = "$mail";
$email_to = "someone@gmail.com"; 
$email_message ="test message";


$email_subject = "Registration form "; // email subject line

$headers .= 'MIME-Version: 1.0'."\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1'."\r\n";
$headers .= 'From:'.$mail;
mail($email_to, $email_subject, $email_message, $headers);
</code></pre>
