problem with multipart/mixed Attachement

[Anon]

Hi Folks,

I wonder if anyone can find the problem. I generate a multipar/mixed attachement, everything looks nice, but the Mailer doesn't recognise it. I bet there it is something wrong with the Formating. Anyone got a clue what might be wrong ? The Mail is not recognised as a Multipart/mixed - but shown as a plain text-Mail.
Here is what the system generates:
From: [e-mail]
Reply-To: [e-mail]
X-Mailer: PHP/4.0.4pl1
Content-Type: multipart/mixed;
boundary="------=_NextPart_POSTCARD_MESSAGE_TAG_5_63"
Date: Mon, 04 Mar 2002 10:04:46
Message-ID: <[e-mail]>
MIME-Version: 1.0

This is a multi-part message in MIME format.

------=_NextPart_POSTCARD_MESSAGE_TAG_5_63
Content-Type: text/plain;
charset="iso-8859-1"
Content-Transfer-Encoding: 7bit

And here is the Code to generate this:
// Preparation for the Mail.
$A_Tag="------=NextPart_POSTCARD_MESSAGE_TAG" . $pic[gal_id] . "_" . $pic[pic_id];
$Signature="\n\n--\nThis message was sent to you through the Image gallery at $titlebar\nURL\
: $nuke_url\nPlease notify errors to $adminmail\n";

            $size = filesize($post[post_file]);
            $type = filetype($post[post_file]);

            // get the content of the file in a string
                $PtrAttachedFile = @fopen($post[post_file],"r");
            $TmpAttachement = @fread($PtrAttachedFile, $size);
            @fclose($PtrAttachedFile);
            $TmpAttachement="This is supposed to be replacement the Attachement binary... for testing";
            $b64_attachement=base64_encode($TmpAttachement);
            $Attachement = chunk_split($b64_attachement, 64 , "\r\n");

            // Subject
            $Subject =  stripslashes($post[post_subject]);

            // thats for the Message itself
                $Message .= "From: $post[post_from]\n";
                $Message .= "Reply-To: $post[post_from]\nX-Mailer: PHP/" . phpversion() . "\n";
                $Message .= "Content-Type: multipart/mixed;\n\tboundary=\"" . "$A_Tag\"\n";
                $Message .= "Date: " . date("D, d M Y H:i:s") . "\n";
                $Message .= "Message-ID: <$sitename" . date("dmYHis") . "$post[post_from]>\n";
                $Message .= "MIME-Version: 1.0\n"; // Mime Header
                $Message .= "\nThis is a multi-part message in MIME format.\n\n";
                $Message .= $A_Tag . "\n";

                $Message .= stripslashes($post[post_message]);
                $Message .= $Signature;
                $Message .= "\n" . $A_Tag . "\n";
                $Message .= "Content-Type: " . $pic[pic_filetype] . ";\n";
                $Message .= "\tname=\"" . $pic[pic_filename] . "\"\n";
                $Message .= "Content-Transfer-Encoding: base64\n";

                $Message .=  $Attachement;
                $Message .= "\n" . $A_Tag . "\n";


            if (mail("$post[post_to]","$Subject","$Message","$Header")) {
                $msg="E-Mail successfully sent to $post[post_to] ...";
            } else {
                $msg="An unknown error occured while trying to send the Mail. Sorry ...";
            }

Note that there is a <NL><TAB> after all ";" as in Content-Type: multipart/mixed; - It's not shown in this forum.

You need to take 2 dashes off in your boundary declaration in Content-Type. You also need to have another boundary at the end of the message - this one must have 2 extra dashes added to the end.

In summary:

Content-Type: multipart/mixed; boundary="----=_NextPart_POSTCARD_MESSAGE_TAG_5_63"

------=_NextPart_POSTCARD_MESSAGE_TAG_5_63

blah

------=_NextPart_POSTCARD_MESSAGE_TAG_5_63

blah2

------=_NextPart_POSTCARD_MESSAGE_TAG_5_63--

HTH.

You're the Man. That was the problem.
Guess I should get hold of the RFC before asking some stupid questions like this one.

Thx a lot for your Time.

Cheers

That's what they're there for 🙂

I also found looking at example emails was a good way to learn, when I was doing something similar.
