Here is a example script for the bug:

<html><head><title>Untitled</title></head>

<body>
<?
       mail("christian@factory", "This is the subject", "This is the body\n", "From: christian@factory.dk");
?>
       It's done it again	

</body>
</html>

I'm trying to send an email to a non existing domain "factory" instead of "factory.dk". The PHP script apparently goes crazy and try sending the mail again every minute for a couple of days... Our mailsystem sends the sender
and error message every times. With a thousand sendings a day the system returns thousan error messages a day.  Big time SPAM!

This is not a PHP issue.  PHP just hands the mail off to either sendmail or in your case it probably sends it directly to an smtp server.  It just does this once.  The delivery agent you are using is doing the retries.
