The custom_headers envelope documentation is misleading. Its not actually an "associative array", its a regular array of headers.

This is wrong:

<?php
$envelope = [
    //...
    "custom_headers" => [
        "X-SES-CONFIGURATION-SET" => "example",
        "X-SES-MESSAGE-TAGS" => "emailType=example"
    ]
];
?>

This is right:

<?php
$envelope = [
    //...
    "custom_headers" => [
        "X-SES-CONFIGURATION-SET: example",
        "X-SES-MESSAGE-TAGS: emailType=example"
    ]
];
?>

So following on from their example, once you've composed your email with attachment or whatever, you'll probably want to send it.

since imap_mail(...) takes the message as body and re-encodes it, ignoring all the hard work you've done already.

Only real solution I found is to post it yourself:

// open connect to mail server
$socket=socket_create(AF_INET,SOCK_STREAM,SOL_TCP);
if ($socket===false) {
    die('Error: socket_create, '.socket_strerror(socket_last_error()));
}

$server="myserver.com"; // say 10.0.0.1 or whatever your mail sever is
$port=25;  // again your mail server port, here generic smtp
if (socket_connect($socket,$server,$port)) {
    print "Connection successful\n";
}else {
    die('Error: socket_connect, '.socket_strerror(socket_last_error()));
}

// send it...
socket_write($socket,"HELO {$envelope["from"]}\n");
socket_write($socket,"MAIL FROM: {$envelope["from"]}\n");
socket_write($socket,"RCPT TO: {$envelope["to"]}\n");
socket_write($socket,"DATA\n");
socket_write($socket,"$message\n");
socket_write($socket,".\n");
socket_write($socket,"QUIT\n");

// done...
socket_close($socket);

Ofcourse the shell may work for you?

echo "Hello World" | mail -s "Greeting..." -a "attachSomeFile.txt" gspot@gmail.com

For some email clients its necessary first to start with the body text and end with the attachment(s). Otherwise all the parts end up in attachments, also the body text (took a while to find this).

So example #1 (above) should be switched over, like:

$body[1] = $part1;
$body[2] = $part3;
$body[3] = $part2;

Since at least PHP 4.3 the $part[] hash can contain the $part['type.parameters'] which expects a hash.

Unfortunately for "hans at lintoo dot dk" there doesn't appear to have ever been $part['parameters.name'] or a $part['dparameters.filename']

So it would appear the corrected code for his function is

<?php
            $part["type"] = TYPEAPPLICATION;
            $part["encoding"] = ENCBASE64;
            $part["subtype"] = "octet-stream";
            $part["description"] = $file_name;
            $part['disposition.type'] = 'attachment';
            $part['disposition'] = array ('filename' => $file_name);
            $part['type.parameters'] = array('name' => $file_name);
            $part["contents.data"] = base64_encode(fread($file_handle,$file_size));
?>
While this correctly sets the header

Content-Type: application/octet-stream; name="file_name"
Content-Transfer-Encoding: BASE64
Content-Description: file_name
Content-Disposition: attachment; filename="file_name"

But this is still not a good idea to blanket set every attachment as a application/octet-stream so please consider using the unix command file, or Fileinfo functions (or even trusting file upload mimetype) and pay attention to the code from "derf dot m at reseaunix dot net"

Here is a little something for attaching files... This is already documented in the manual, but my solution involves some changes. This is based on testing and suggestions from others notes on this page.
<?php
//snip
if (count($_FILES) > 0) {
    $multipart["type"] = TYPEMULTIPART;
    $multipart["subtype"] = "mixed";
    $body[] = $multipart; //add multipart stuff
}
//snip
$uploaddir = ini_get("upload_tmp_dir"); //Get tmp upload dir from PHP.ini
foreach ($_FILES as $fieldName => $file) {
    for ($i=0;$i < count($file['tmp_name']);$i++) {
        if (is_uploaded_file($file['tmp_name'][$i])) {
            $file_handle = fopen($file["tmp_name"][$i], "rb");
            $file_name = $file["name"][$i];
            $file_size = filesize($file["tmp_name"][$i]);
           
            $part["type"] = TYPEAPPLICATION;
            $part["encoding"] = ENCBASE64;
            $part["subtype"] = "octet-stream";
            $part["description"] = $file_name;
            $part['disposition.type'] = 'attachment';
            $part['disposition'] = array ('filename' => $file_name);
            $part['dparameters.filename'] = $file_name;
            $part['parameters.name'] = $file_name;
            $part["contents.data"] = base64_encode(fread($file_handle,$file_size));
           
            $body[] = $part;
            unlink($file["tmp_name"][$i]);
        }
    }
}
//snip
?>
hope someone can use this...

I got a lot of problems with attachments (multipart emails) and the fix directly below this note.
instead just include it in the optional headers argument as previously suggested:

<?php
$mail = str_replace("\r","",imap_mail_compose($envelope, $body));
imap_mail($_POST["to"],$_POST["subject"],'',$mail);
?>
"Nothing like a fix on a fix".

If you want to copy the message to ie: a sent folder do:
<?php
//take note of the link: $this->mbox, and the constant: self::$imapStream
$envelope["to"]  = $_POST["to"]; //included with imap_mail
$envelope["subject"]  = $_POST["subject"]; //included with imap_mail
$mail = imap_mail_compose($envelope, $body); //note no problems with \r
imap_append($this->mbox,self::$imapStream."INBOX.Sent",$mail ,"\\Seen");
?>
See imap_append for more info.... Enjoy!

It is a good idea to set the date header:
$envelope['date']=date('r');
thomas dot hebinck at digionline dot de 06-Sep-2003 05:26
imap_mail_compose modifies $envelope! Subsequent calls with the same $envelope may not work depending on the contents of the header. The best way (at least it works) I found, is:

$temp_env=unserialize(serialize($envelope));
$mail=imap_mail_compose($temp_env,$body);

(just $temp_env=$envelope does not work either)

If you wish to send the output of this function, simply use it for the headers argument of imap_mail() or mail().  Keep in mind that those functions set the To: and Subject: headers, so including them in the envelope will create double entries.

In regards to my earlier note about "charset", this feature seems to have been added in the 4.1.X series  I have not actually checked 4.1.0, but it is in 4.1.1 and not it 4.0.6.
trionon at mail dot ru 28-Jan-2002 11:03
At least the following items in $part[] hashes are parsed:

type
encoding
charset
subtype
id
description
disposition.type
disposition
contents.data
lines
bytes
md5

Note: $part['disposition'] is a hash:

$part['disposition.type'] = 'attachment';
$part['disposition'] = array ('filename'=>'file.txt');

This will transform in such part header:

Content-disposition: attachment; filename="file.txt"
vlad ( at php dot net) 15-Jan-2002 06:18
... and the headers (elements of the envelope) are case-sensitive and are listed below:

remail
return_path
date
from
reply_to
in_reply_to
subject
to
cc
bcc
message_id
custom_headers

If you can't find a header you need in this list, you can use 'custom_headers'. It is just an array of lines to be appended to the header without any formatting, like this:

$envelope["custom_headers"] = Array("User-Agent: My Mail Client", "My-Header: My Value");

TODO: This should really migrate from a note to documentation
prices at dflytech dot com 07-Jan-2002 09:22
The documentation above does not mention that you can use the index ["charset"] to set the character set of the messsage part.

Example:

$part1["type"]= "TEXT";
$part1["subtype"]="PLAIN";
$part1["charset"] = "koi8-r";

to send a message in Russian-koi8.
