PHP Mail Rejected from Hotmail

[whchapman]

Hello,

Here is my user info:
Login Name: phsoa
Subdomain: phsoa.x10hosting.com
Package: Ad-Free

I am having trouble with PHP generated email being rejected by hotmail email addresses. Consider the following simple script:

<?php
mail("myemail@gmail.com, myemail@aol.com, myemail@hotmail.com", "Test Subject", "Random email message", "From: phsoa@phsoa.x10hosting.com");
?>

The email is delivered properly to the Gmail and AOL addresses. But I receive the following bounce message from Hotmail. What gives? Do I need to include some special header?

I'll notify the admins that we are still having the hotmail problem.

Thanks for your help Christopher.

The problem appears to affect Yahoo Mail also. But Yahoo doesn't send me a bounce message. It just never shows up in my inbox, or my spam folder. Weird. . . Had you been having problems with Yahoo before also?
