Sending as Junkmail

[DarkPrince2005]

Is there anyway i can make the email to not be recognised or sent as junkmail

 

<?php

$filename='test.txt';
$arremails=file($filename);

for ($i=0;$i<=$arremails; $i++){
$subject = 'Test HTML email';
//create a boundary string. It must be unique
//so we use the MD5 algorithm to generate a random hash
$random_hash = md5(date('r', time()));
//define the headers we want passed. Note that they are separated with \r\n
$headers = "From: email@isp.co.za\r\nReply-To: email@isp.co.za";
//add boundary string and mime type specification
$headers .= "\r\nContent-Type: multipart/alternative; boundary=\"PHP-alt-".$random_hash."\"";
//define the body of the message.
ob_start(); //Turn on output buffering
?>
--PHP-alt-<?php echo $random_hash; ?> 
Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit

[i][b]Plain text email[/b][/i]

--PHP-alt-<?php echo $random_hash; ?> 
Content-Type: text/html; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit
[i][b]HTML Formatted mail[b][/i]--PHP-alt-<?php echo $random_hash; ?>--
<?

//send the email

//copy current buffer contents into $message variable and delete current output buffer
$message = ob_get_clean();
mail($arremails[$i], $subject, $message, $headers);
};
?>

proper headers is the biggest thing

To prevent this, mail has to be sent as SMTP mail. You can do this using the phpmailer class (its free, google it) and set the mail to be isSmtp()
