MIME Multipart Message in PHP not sending

Question

I am trying to send a MIME Multipart Message in PHP but it is not sending. I have come to the conclusion that this may be because of a problem with the MIME syntax somewhere, but I do not know where.

Here is the code:

$Subject = "****** Contact Form";
$Name = trim(stripslashes($_POST['Name'])); 
$Email = trim(stripslashes($_POST['Email'])); 
$Message = nl2br(trim(stripslashes($_POST['Message'])));
$MessagePlain = trim(stripslashes($_POST['Message']));
$ReferredBy = $_POST['referredby']; 
$Other = trim(stripslashes($_POST['othertext'])); 
$Day = $_POST['Day']; 
$Month = $_POST['month']; 
$Year = $_POST['year']; 

if ($Month = 1) {
        $Month = 'January';
    } elseif ($Month = 2) {
        $Month = 'February';
    } elseif ($Month = 3) {
        $Month = 'March';
    } elseif ($Month = 4) {
        $Month = 'April';
    } elseif ($Month = 5) {
        $Month = 'May';
    } elseif ($Month = 6) {
        $Month = 'June';
    } elseif ($Month = 7) {
        $Month = 'July';
    } elseif ($Month = 8) {
        $Month = 'August';
    } elseif ($Month = 9) {
        $Month = 'September';
    } elseif ($Month = 10) {
        $Month = 'October';
    } elseif ($Month = 11) {
        $Month = 'November';
    } elseif ($Month = 12) {
        $Month = 'December';
}

$MIMEBoundary = md5(uniqid(rand()));

// prepare email headers
$Headers  = "MIME-Version: 1.0\r\n";
$Headers .= "From: ******\r\n";
$Headers .= "Reply-To: ****** <******@hotmail.com>\r\n";
$Headers .= "Content-type: multipart/alternative; boundary=$MIMEBoundary\r\n";

// prepare email body text
$Body = "--" . $MIMEBoundary . "\r\n";
$Body .= "Content-type: text/html;charset=\"ISO-8859-1\"\r\n";
$Body .= "Content-Transfer-Encoding: base64\r\n\r\n";

The problem

There are several problems with your code:

The delimiter between the first and second body part is incorrect

 $Body .= "\\r\\n\\r\\n--' . $MIMEBoundary . '\\r\\n";

The line above will output single quotes and dots. It should read:

 $Body .= "\\r\\n\\r\\n--" . $MIMEBoundary . "\\r\\n";

or

 $Body .= "\\r\\n\\r\\n--$MIMEBoundary\\r\\n";

The close-delimiters in both emails are incorrect

 $Body .= "\\r\\n\\r\\n--" . $MIMEBoundary; $Body2 .= "\\r\\n\\r\\n--" . $MIMEBoundary;

The close-delimiter must end in two dashes, so the lines above should read:

 $Body .= "\\r\\n\\r\\n--" . $MIMEBoundary . "--"; $Body2 .= "\\r\\n\\r\\n--" . $MIMEBoundary . "--";

or

 $Body .= "\\r\\n\\r\\n--$MIMEBoundary--"; $Body2 .= "\\r\\n\\r\\n--$MIMEBoundary--";

Incorrect content encoding
If you specify Content-Transfer-Encoding: base64 you must also base64_encode() (and chunk_split() ) that body part.

See also Final Notes below.

MIME Syntax

This is an excerpt of what the structure of a multi-part message body looks like according to RFC 2046. (BNF syntax, somewhat simplified.)

multipart-body := [preamble CRLF]
                  dash-boundary CRLF
                  body-part *encapsulation
                  close-delimiter
                  [CRLF epilogue]

dash-boundary := "--" boundary

body-part := MIME-part-headers [CRLF *OCTET]

encapsulation := delimiter
                 CRLF body-part

delimiter := CRLF dash-boundary

close-delimiter := delimiter "--"

Final Notes

The variables that are expanded inside the HTML email body (eg. $Name etcetera) should be escaped with htmlspecialchars() .

It would be much easier to understand the structure of the email message if you store each body part in variables:

 $Body = "--$MIMEBoundary\\r\\n"; /* First dash-boundary */ $Body .= "Content-type: text/html;charset=\\"ISO-8859-1\\"\\r\\n"; $Body .= "Content-Transfer-Encoding: base64\\r\\n"; $Body .= "\\r\\n"; $Body .= $Body_part1; $Body .= "\\r\\n--$MIMEBoundary\\r\\n"; /* delimiter */ $Body .= "Content-type: text/plain;charset=\\"ISO-8859-1\\"\\r\\n"; $Body .= "Content-Transfer-Encoding: base64\\r\\n"; $Body .= "\\r\\n"; $Body .= $Body_part2; $Body .= "\\r\\n--$MIMEBoundary--"; /* close-delimiter */ /* You only need a single CRLF between body part and delimiter. */

Personally, I would test if the MIME boundary string occurs in any of the body parts before using it, but then I would also use much shorter boundary strings. But that's just me. Normal people don't do that.
