sat 21st php mail() stopped working properly

it stopped sending mail to any server but mine

[nippon]

Dear All,

A somewhat annoying and perplexing problem.
Last saturday my script which sends html emails to various people stopped sending it to them and was only able to send it to my email on the same server.

Since then i've been unable to use even a simple php mail() script to send email to my yahoo or hotmail accounts.

i've checked for a spam blacklist, seems all clear.

does anyone know of why this might be?

here are the headers:

$header = 'MIME-Version: 1.0' . "\r\n";
$header.= 'Content-type: text/html; charset=utf-8' . "\r\n";
$header.= "X-Sender: < email.com >\r\n";
$header.= "From: Blah <" . $your_email . ">\r\n";
$header.= "Return-Path: < email.com >\r\n"; // Return path for errors
$subject= "Blah";

$to="[e-mail]";

mail($to, $subject, $text, $header);

one thing i've noticed is that the return path dosent change even tho i set it here, it just gives a generic [e-mail]

any help appreciated
thanks

Hi nippon,

It sounds as though your hosting company have stopped the mail function sending to 3rd party addresses. Some hosts do this if the mail function is abused, in which case you may need SMTP authentication to send to other addresses.

Have you contacted your host about the issue?

That sounds like the reason.... your script runs fine for me.
