[RESOLVED] How to setup mail in php.ini

[conjurer]

I am trying to work through some of the Wellington and Thomson book on PHP and MySQL - I am trying to process a mail feedback form and I get the following error:

Warning: mail(): SMTP server response: 451 See http://pobox.com/~djb/docs/smtplf.html. in C:\Documents and Settings\RLane\My Documents\Web Sites\Localhost\InDevelopment\Wellington\Source\04\processfeedback.php on line 14

In the php.ini file I modified the mail settings to be:

[mail function]
; For Win32 only.
SMTP = mail.mind.net

; For Win32 only.
sendmail_from = [e-mail]

The form uses the following code to process the form - what do I have broken?

 //create short variable names
  $name=$_POST['name'];
  $email=$_POST['email'];
  $feedback=$_POST['feedback'];

  $toaddress = '[e-mail]';
  $subject = 'Feedback from web site';
  $mailcontent = 'Customer name: '.$name."\n"
                 .'Customer email: '.$email."\n"
                 ."Customer comments: \n".$feedback."\n";
  $fromaddress = 'From: [email][e-mail][/email]';

  mail($toaddress, $subject, $mailcontent, $fromaddress);

😕

I see I had to modify the "/n" to "/r/n" - now it works.
