Swiftmailer mails go into SPAM Folder

Question

$headers = "\r\n" . "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";

$message = Swift_Message::newInstance()
                ->setSubject($subject)
                ->setFrom(array('from@mail.com' => 'From Address'))
                ->setTo(array('to@mail.com' => 'To Address'))
                ->setBody($message_plain_txt)
                ->addPart($message, 'text/html')
        ;
if ($file_name)
        {
            $message->attach(Swift_Attachment::fromPath($file_path));
        }

$result = $mailer->send($message);

In this case $filepath is the tmp path which I am using when a user attaches a files from a form and $file_name is the tmp file name $_FILES['file']['name'].

In this setup I am able to send mails but when there is an attachment, the mail goes into SPAM folder. If there is no attachment then mail goes into inbox.

This setup works perfectly fine when I am uploading a file from a location and not sending the attachment from a form.

I think it has got something to do with the email headers, but i am not able to figure out the error.

Can some one please help me with what mistake I am doing here.

Got it working by modifying headers to

$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type: text/plain; charset=iso-8859-1\n";

Add the following headers to avoid going to spam folder:

$headers .= "Message-ID: <".time()." TheSystem@".$_SERVER['SERVER_NAME'].">\r\n";
$headers .= "X-Mailer: PHP v".phpversion()."\r\n";

thanks for ur help... even by adding the above code, mails are going into spam. – user434509 Feb 10 '12 at 21:02
I'm not sure what's the issue then, this worked for me, it might depend on the server spamfilter... hard to say what's the issue. – Luc Laverdure Feb 10 '12 at 21:13

In versions of SwiftMailer in 2015, you would use built-in getHeaders() method to set headers.

$headers =& $message->getHeaders();
$headers->addIdHeader('Message-ID', "b3eb7202-d2f1-11e4-b9d6-1681e6b88ec1@domain.com");
$headers->addTextHeader('MIME-Version', '1.0');
$headers->addTextHeader('X-Mailer', 'PHP v' . phpversion());
$headers->addParameterizedHeader('Content-type', 'text/html', ['charset' => 'utf-8']);

From the [doc](http://swiftmailer.org/docs/headers.html#adding-new-headers), you don't need to return by ref (`=&`). – IROEGBU Jun 28 '17 at 14:37
