无法通过Yahoo SMTP发送电子邮件

Question

I am trying to use Yahoo SMTP server to send emails from a web site, located on local Windows server and based on Xampp.

As a result, this is what I have in my sendmail settings :

smtp_server=smtp.mail.yahoo.com
smtp_port=465
smtp_ssl=auto
auth_username=[e-mail]
auth_password=pswd1

Then in PHP :

mail ('[e-mail]', 'Static Mail 1', 'Static Message');
mail ('[e-mail]', 'Static Mail 2', 'Static Message');

So, I am trying to send email from one Yahoo account to another but it does not work. I tried to send emails with GMail SMTP and it works fine but when I try to do this through Yahoo SMTP I always get an error :

From address not verified - see http://help.yahoo.com/l/us/yahoo/mail/original/manage/sendfrom-07.html 

As far as I know, this is a common problem when Yahoo does not allow to send emails on behalf of it, but in my case I am sending messages only between Yahoo accounts, what am I doing wrong?

Issue for cross server requests is described here but in some reason I am experiencing it even when I use only Yahoo accounts too.

Seems like the error is pretty self explanatory, add the fourth paramater for the mail function, something like this:

<?php
$to      = '[e-mail]';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: [e-mail]' . "
" .
    'Reply-To: [e-mail]' . "
" .
    'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);
?>
