Question: I wrote a PHP script to send emails.

My script is like this:

```
$headers =  'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'From: abc@yahoo.com' . "\r\n";

// Email Variables
$toUser  = "someone@yahoo.com"; // recipient
$subject = "testing"; // subject
$body    = "<html><body><p>
             Example of including an image via html \<img\> tag:
             <br>
             <img src='../images/profile.jpg'>
             <br>
             My new picture
             <br></p></body></html>"; // content

if (mail($toUser,$subject,$body,$headers)) {
    echo "sent";
} else {
    echo "failed";
}

```

Well, of course I use a valid email address for sender and receiver. I did receive the email, but it goes to junk mail. So I went for google research. Is it because of my "header" script problem? If it isn't, then what could cause my script to send a junk mail? Any solution?

Answer: 
**1. Check mail content**

As others have hinted it is probably marked as spam because your mail looks like spam.

I am not sure if you the script that you have posted is the actual one that you are testing.

If it has the actual mail body & headers, then running this message through a standard installation of SpamAssassin gives it a spam score of 4.9

```

X-Spam-Status: No, score=4.9 required=5.0 tests=BAYES_50,HTML_IMAGE_ONLY_04,
        HTML_MESSAGE,MIME_HTML_ONLY,NO_DNS_FOR_FROM,NO_RELAYS autolearn=no
        version=3.2.5

```

Since the email body has only HTML it has a greater chance of being handled with suspect by most anti-spam solutions.

**2. Mail server's IP**

Another aspect worth checking will be the IP address of your mail server. Any mail originating from dynamic IP addresses will potentially be considered as SPAM. 

**3. Blocklists** 

Also check if your IP address is listed in one of the block lists. To start with please check your IP address with <http://www.spamhaus.org/lookup.lasso>.
Remove the `Content-type: text/html` and add `$headers .= "X-Priority: 2\nX-MSmail-Priority: high";` to get rid of Spam. This method has been tried and tested.
