   /* Execute the query */ 
   $result = mysql_query($query); 
   /* get an array of the table results */ 
   $values = mysql_fetch_array($result); 
$req_email = $values['req_email'];
$new_user = $values['new_user'];
$new_pass = $values['new_pass'];
$new_email = $values['new_email'];
$mail_to= ".$req_email.";
$mail_subject= 'A requested user account has been created' ;
$mail_body= 'User account number ".$key." has been created. The detaisl are as followos: Username = ".$new_user." Password = "$.new_pass." E-mail address = "$.new_email."';

from the error i suppose the email you are sending the email to is not valid. If users are entering those email address then u must validate them before putting them in your DB.

You mite also wana add a "." before you second $header value to concatinate it with the first. Although i dont think that caused the error.

[adamdidthis]

$req_email = $values['req_email'];

looks at a field in the database that does contain an email address

[zeeshan_kh]

check to see if all the email addresses are valid. that includes CC and From

[adamdidthis]

the CC and From addresses are correct, i think the problem is to do with the $mail_to= ".$req_email."; the problem is that I am not sure how to get the mail script to look at the fields i require and then stick the contents in the mail script. any help would be appreciated
