this code should be used just before the mail function, all it does,
is to enforce the format of each "header" - a header here just means
To: email@email.com
From: me@home.com
rather like the headers of an HTTP request
etc... the part before the : cprresponds to $to $from etc.. the part
afterwards to the value
of $to $from etc...
so that it won't allow the value of one header to actually be two
headers together - which would smuggle in more BCC address rather than
the single value you wanted to allw.
Its a neat method.
Phpmailer has this all built in so that the code you write is all
about the stuff you need rather than a whole lot of extra checking
etc...
see this example:
require_once('class.phpmailer.php');
$mail = new PHPMailer();
// set mailer to use SMTP
$mail->IsSMTP();
// specify main and backup server
$mail->Host = 'auth.smtp.server.com';
// turn on SMTP authentication
$mail->SMTPAuth = true;
// SMTP username
$mail->Username = $username;
// SMTP password
$mail->Password = $password;
//$mail->SetLanguage("br", "/optional/path/to/language/directory");
$mail->From = $from;
$mail->FromName = $fromname;
$mail->AddAddress($to, $toname);
$mail->AddReplyTo($reply, $replyname);
$mail->WordWrap = 50;
$mail->IsHTML(true);
$mail->Subject = $subject;
$mail->Body = $body;
easy huh
