PHP mail() problem with MSN Hotmail email account

Hi!

I created a contact form that will mail the form to my email, which hotmail account. I use php mail() function to send mail to my hotmail account.

However, there is a problem when I click submit on the contact form. The email won’t send to my hotmail. If I send it to email providers like yahoo or gmail, there is no problem, the email just sent out successfully. Somehow, my hotmail account won’t receive anything from php Mail() function.

I did a test like:

success = mail($to, $subject, $msg, $header);

The result says that the mail() has successfully sent the email out. But I never receive it in my hotmail account.

I contact few people from other forums and they have the same problem. Do you guys have the same problem here too?

Many many thanks for your help and time.
