I recently bought a product called "1-2-3 music store". And this webshop needs to send mail via PHP but it doesn't work. I got a test script and when I try to send an email I get this "SMTP server response: 553 We do not relay non-local mail, sorry."

Please help me if you know what is causing this problem.

Best regards,
Tobiah

Where are you sending email through? Are you using the Mercury that comes with Xampp, or sending through your ISP's mail server?
