Question

I am working for my college website . I wrote a php script ,that sends email using php mail function. But the problem is ,all the emails that I send is going into the recipients spam /Junk Folder.

In order to resolve it :

I tried all the steps and answers for the similar issues in stackoverflow and serverfault website Like:
*Proper Header
*Accurate From Name,etc
But yet the problem is unresolved.

This is the php code for sending email:

<?php
$from_address="webmaster@".$_SERVER['SERVER_NAME'];
$from_name="webmaster";
$headers = "MIME-Version: 1.0\r\n"
  ."Content-Type: text/plain; charset=utf-8\r\n"
  ."Content-Transfer-Encoding: 8bit\r\n"
  ."From: =?UTF-8?B?". base64_encode($from_name) ."?= <$from_address>\r\n"
  ."X-Mailer: PHP/". phpversion();
$subject="Web Mail Testing";
$body="This is test Message";
$to="[e-mail]";
mail($to, $subject, $body, $headers, "-fwebmaster@{$_SERVER['SERVER_NAME']}");
echo "The Mail is  SuccessFully Sent to :".$to;
?>

I am also attaching the original email (that i received in my gmail account “[e-mail]”)

This is test Message

Also while googling I found the uncommon reason for this sort of problem is server Blacklisting .

Then I use the following Tool to test it : http://www.mxtoolbox.com/SuperTool.aspx?action=mx%3anitw.ac.in#

I got shocked when the above tool test found my server in the black-list. How is this true?Since the original mail that i attached above says “:Received-SPF: pass (google.com: best guess record for domain of [e-mail] designates 218.248.13.200 as permitted sender)

Also if my server is blacklisted , then how can i find the reason for blacklist and how to resolve it?

UPD:
From Shadow Comment : Can “X-Authentication-Warning: http://www.nitw.ac.in: nobody set sender to [e-mail] using -f” msg be the probable reason? If yes , How can I Fix it?

Thank You!

Setting up SMTP server is tricky and tedious task unless it is ur job do it day in and day out.., Check if your server SSL certificate are signed properly with an authorized CA certificate., some times it could be the problem of a self signed certificates .,

Or you can also try out Gmail As your SMTP server which solves many problems .., Link
