Mail() Gets Blocked By Hotmail... Any Ideas?

[chain2005]

Hello,

 

I have a few systems that rely on the php mail function. One really big problem I'm having is I'm always blocked in Hotmail and marked as "junk mail". Does anyone know a solution to this? See below for my headers:

 

# Common Headers
$eol = "\r\n";
$headers .= 'From: <'.$fromaddress.'>'.$eol;
$headers .= 'Reply-To: <'.$fromaddress.'>'.$eol;
$headers .= 'Return-Path: <'.$fromaddress.'>'.$eol;    // these two to set reply address
$headers .= "Message-ID: <".$now." TheSystem@".$_SERVER['SERVER_NAME'].">".$eol;
