title: SMTP Error(220-We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail.)
body: <p>I am current using CodeIgniter 2.2.2 and I have the following code inside my controller:</p>
  
  <pre><code>        $config['protocol'] = "smtp";
          $config['smtp_host'] = "mail.domain.com";
          $config['smtp_port'] = "25";
          $config['smtp_user'] = "noreply@somedomain.com"; 
          $config['smtp_pass'] = "password";
          $config['charset'] = "utf-8";
          $config['mailtype'] = "html";
          $config['newline'] = "\r\n";
          $config['wordwrap'] = TRUE;
          $this-&gt;load-&gt;library('email');
          $this-&gt;email-&gt;initialize($config);
  
          $this-&gt;email-&gt;set_mailtype('html');
          $this-&gt;email-&gt;from('noreply@somedomain.com', 'www.somedomain.com');
          $this-&gt;email-&gt;to('someEmail');
  
  
          $this-&gt;email-&gt;subject('Email Authentication');
          $message = 'Hi';
  
          $this-&gt;email-&gt;message($message);
  
          $this-&gt;email-&gt;send();
  </code></pre>
  
  <p>I tried using port 465, and ssl://xxxxxxx.prod.iad2.secureserver.net. But i am getting no luck at all. I tried contacting the customer service, but nope. They really didn't help me much other than giving me links into things I already knew.
  Why am I getting the message? It is preventing me to send email to my other email addresses.
  Can anyone please help here?</p>
