MY SMTP mail keeps coming through as Junk

Question

I know this is plastered all over the net... But i've tried a lot of solutions and it just wont seem to work. My SMTP mail first came through as junk, and now just comes into my inbox, but with a warning notice saying the email didnt pass the fraud tests..

So im using Optus's SMTP server (mail.optusnet.com.au), and for the "sendmail_from" i have my email address..

for the actual mail, i have this:

$message = 'Hello, $user;

$to      = '[e-mail]';
$subject = 'Welcome';
$headers = 'From: [e-mail]' . "\r\n" .
           'Reply-To: [e-mail]' . "\r\n" .
           'X-Mailer: PHP/' . phpversion();

mail('[e-mail]', $subject, $message, $headers);

Any ideas guys?

Thanks,

Adam

Most of E-Mail providers check every received email to decide whether it's a spam or not. For example , if you send an email as [e-mail] from mail.optusnet.com.au , it will not pass the test and will be put under junk category. In my experience, Yahoo! and Hotmail usually put every email with X-Mailer: PHP header as junk!

For more information take a look at Sender Policy Framework.

About comment: If you take a look at your received email, you will see something like this:

Received-SPF: neutral (google.com: x.x.x.x is neither permitted nor denied by best guess record for domain of [e-mail]) client-ip=x.x.x.x;

it tells client that this email at least is NOT trying to show itself as someone else, so it goes to your inbox. but If you use [e-mail], since hotmail.com has a valid IP and it's different from mail.optusnet.com.au, so it goes to your junk folder.
