I'm using Postal to send emails with an HTML and Text portion.
When the email is sent to Gmail, it is displayed correctly. However, when it is displayed in at least two other email systems (Mail Enable's webmail interface, and an unknown system at a client), the text is rendered as something similar to Chinese. When the client forwards the email back to a Gmail account, the "Chinese" rendering is also visible.
Example email generated:
X-Sender: no-reply#thecompany.com
X-Receiver: therecipient#thecompany.com
MIME-Version: 1.0
From: no-reply#thecompany.com
To: therecipient#thecompany.com

Clearly there is an encoding issue that Gmail somehow sorts out but other email servers do not, but what exactly is the issue?
The charset is specified as utf-16. Is does Postal (or the MVC engine) in fact generate utf-8 output? How can I control the encoding of the output and/or the charset specified in the email header?
The character encoding can be explicitly set to utf-8 by adding the headers
Content-Type: text/plain; charset=utf-8
and
Content-Type: text/html; charset=utf-8
See this article for more information.
NOTE: There is a typo in the article. The text/plain line is missing a semicolon. That is corrected in the example above.

Does anyone know how to send a mail with an attachment using Amazon SES with the iOS SDK.
To send an email with SES using the iOS SDK you need to create a AWSSESSendRawEmailRequest and make sure that the rawMessage (AWSSESRawMessage) data format complies with Internet email standards regarding email header fields, MIME types, MIME encoding, and base64 encoding.
This means converting the NSData of your attachment to a base64 string and inserting it in the raw email string with all the headers etc.
Such a string may look something like this:
From: "Bob" <bob#example.com>
To: "Andrew" <andrew#example.com>
Date: Wed, 2 Mar 2011 11:39:34 -0800

Note that AWSSESRawMessage has a data (NSData) property so this string will need to be converted to NSData before using it in AWSSESRawMessage
Im constructing a MIME essentially from scratch to send emails with attachments using Amazon's SES SDK for iOS. By producing the following MIME and encoding it into a NSData object I am able to receive an email with an attached email:
From: me <from#example.com>
To: to#example.com
Subject: "example subject"
MIME-Version: 1.0
Content-Type: image/png
Content-Disposition: attachment; filename="img.png"
Content-Transfer-Encoding: base64
[giant string of base64 encoded png file omitted for brevity]
However I want to also have a plain text message in the body of the email, but I haven't been able to get my multipart/mixed message with the following format to be parsed correctly. It sends as an email with a "noname" attachment containing all the text after the first boundary.
From: me <from#example.com>
To: to#example.com
Subject: "example subject"
MIME-Version: 1.0
Content-Type: multitype/mixed; boundary="boundary--boundary--boundary"
--boundary--boundary--boundary
Content-Type: text/plain
example plain text
--boundary--boundary--boundary
Content-Type: image/png
Content-Disposition: attachment; filename="img.png"
Content-Transfer-Encoding: base64
[giant string of base64 encoded png file omitted for brevity]
--boundary--boundary--boundary--
Does anyone see something wrong with how I'm formatting the second MIME?
Thanks for your help.
You're using the wrong Content-Type. The correct MIME type for a message with this structure is multipart/mixed, not multitype/mixed.
<?xml version="1.0" encoding="utf-8"?>
<SendMail xmlns="ComposeMail:" xmlns:airsync="AirSync">
<ClientId>34234243</ClientId>
<SaveInSentItems />

Content-Transfer-Encoding: base64
X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2900.3350 234234
This is body
</Mime>
</SendMail>
I am working with SendEmail command. I am looking for way to send Mime content to server. I have tried:
Convert the above xml in wbxml and setBOdy HTTP request but server return 103 error code.
Convert the Content betweent to Base64, and append to old string like this:
<?xml version="1.0" encoding="utf-8"?>
<SendMail xmlns="ComposeMail:" xmlns:airsync="AirSync"><ClientId>34234243</ClientId>
<SaveInSentItems/>
<Mime>
text encode base 64
</Mime>
</SendMail>
And convert to wbxml, send to server and receive error code 119 mean :MessageHasNoRecipient
The message being sent contains no recipient.
Anybody help? thanks in advance
I am sure you have a blank character before the "To" keyword in your code.
Let's remove it. Your data before you encode it to base64 encoding must to look like this:
From: xxx#xxx.com
To: xxx#xxx.com
Subject: Mail Subject
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: base64
Test body
Best regards,
From MS documentation Mime element must be opaque BLOB https://msdn.microsoft.com/en-us/library/gg663453(v=exchg.80).aspx.
So you must write Mime data as CDATA.
<Mime>
<![CDATA[From: xxx#xxx.com
To: xxx#xxx.com
Subject: Mail Subject
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8

i am sending an e-mail with a doc file attachment. I am receiving the mail but with no any attachment.
PHP
$file_resume = '';
if (!empty($_FILES['attachment_file_name']['tmp_name'])) {
$file = $_FILES['attachment_file_name']['name'];
$attachment= file_get_contents($file);
$attachment= chunk_split(base64_encode($attachment));
}
$uid = md5(uniqid(time()));
$headers= "From: no-reply#edu.in"."\r\n";
$headers.= "Reply-To: no-reply#edu.in"."\r\n";
$headers.= "X-Mailer: PHP/" . phpversion()."\r\n Content-Type: multipart/mixed; boundary=\"PHP-mixed-".$uid."\"\r\n";
$headers.= "MIME-Version: 1.0" . "\r\n";
$headers.= "Content-type: text/html; charset=utf-8"."\r\n Content-Disposition: attachment; filename=\"".$attachment."\"\r\n";
$message = $_POST['person_name'];
mail($to,$subject,$message,$headers);
Html
<form id="attachment" action='mailer.php' method='POST' name="attachment" enctype="multipart/form-data">

<br />

</form>
If you're going to try to manually send an email with attachment(s), you need to get to know the underlying mail text packet that actually represents what you're constructing with the mail() arguments. Unless you comprehend and understand what's going on here, you'll struggle to ever get your email with attachment to send. There's too many sharp edges.
Gmail has a nifty feature on emails to view the original message packet, in plaintext. It's called Show Original. When testing your email script, use a Gmail account if you can so you can inspect the actual email plaintext packet. To Show Original, go to the top, left dropdown triggered by the down arrow next to the reply arrow of an email.
So sending a test email to myself with an image attached, we have what's below. Your mail call, essentially, has to translate into something more or less like this example.
Especially note how the headers start off (the top five headers below you will not handle, except maybe MIME-Version). At the end of that block, you have:
Content-Type: multipart/mixed; boundary=089e0118416874703004d86a5106
The part following the = is a message part boundary, which allows you to add multipart message blocks, including attachment file contents that have been encoded and given appropriate sub-part headers.
So there's:
--089e0118416874703004d86a5106
... message block(s) ...
--089e0118416874703004d86a5106--
There's actually another boundary declared, with:
Content-Type: multipart/alternative; boundary=089e0118416874702b04d86a5104
Which involves the text/plain and text/html dual message formats. This is not required, but many mail clients do it by nature. You can choose either text/plain or text/html, it's up to you and how your comment is formatted.
Next we see:
--089e0118416874703004d86a5106
Content-Type: image/jpeg; name="opinion (2).jpg"
Content-Disposition: attachment; filename="opinion (2).jpg"
Content-Transfer-Encoding: base64
X-Attachment-Id: f_hejlmnuz0
/9j/4AAQSkZJRgABAgAAAQABAAD/2wBDAAIEBAYIBggICAgICAgICAgKCgoKCgoKCgoKCgoKCgoK
... lots of lines for the encoded file block ...
W5R3W8ajLwrgUJEDGKWN2kWvO5iB7qdKwB6MwwfqVrQKcObveZxZBtQNCp0vc//Z
--089e0118416874703004d86a5106--
Note that the boundary's have a trailing -- at the end of their blocks (not each block).
Take a look below and compare that to the code that luk3thomas has in his answer. Try sending a very simple email message to yourself, and compare that to an attachment-formatted email:
mail('your#email.com', 'Simple mail test', 'Test message body content.');`
You should start to get the idea what's required to send emails with attachments included. The thing is, formatting an email packet for sending is very particular and little things can cause it to fail. So you have to pay attention.

You'll need to add the attachment into the body of the email message. Try something like this:
$random_hash = md5(time());
$headers .= "\r\nContent-Type: multipart/alternative; boundary=\"PHP-alt-".$random_hash."\"";
$headers .= "\r\nMIME-Version 1.0";
$attachment = chunk_split(base64_encode(file_get_contents($filename)));
$message =
"--PHP-alt-$random_hash
Content-Type: text/plain
Dear Same,
We would like to thank you for your registration to be held on Saturday August 25, 2012 at the....
--PHP-alt-$random_hash
Content-Type: application/pdf; name=$filename
Content-Transfer-Encoding: base64
Content-Disposition: attachment
$attachment
--PHP-alt-$random_hash--";
#mail($to, $subject, $message, $headers);
I've got a mailer that as follows:
class Payments::LateNoticesMailer < AsyncMailer
def notice(payment_id)
#payment = PaymentDecorator.find(payment_id)
#invoice = #payment.invoice
template = "payments/invoices/#{#payment.made_with_type.downcase}/show"
attachments["#{#payment.invoice_filename}.pdf"] =
WickedPdf.new.pdf_from_string( render_to_string( pdf: #payment.invoice_filename,
formats: [:pdf],
template: template,
layout: "layouts/pdf.html"))
mail to: #payment.payer_email,
from: '"RentingSmart" <no-reply#rentingsmart.com>',
cc: #payment.landlord_email,
subject: "*** Your rent payment of #{#payment.amount_due} is overdue ***"
end
end
which I send using SendGrid. Here's my issue, if I open up the email via Gmail, everything works great, the text of the email is there, and the attachment is attached. However, if I open it up using OSX's Mail.app or on my iPhone, I simply get the following:
This is a multi-part message in MIME format...
Anybody have any tips? I think I am following the Rails guides correctly.
Here is the call that I make Payments::LateNoticesMailer.notice(payment.id).deliver
According to the api docs for ActionMailer::Base, if multiple template types are used, all of them are rendered and the mime-type is automatically set to multipart/alternative.
If you add an attachment, the attachment is placed inside a multipart/mixed container.
First question: Are you rendering other types such as text and html? I would not recommend sending out emails with just a pdf part. Even if the text and html parts simply instruct the recipient to open the attachment, they should be there. Ideally, there would be more information in the text/html parts.
Second, are you trying to view the pdf inline, and not as an attachment?
Can you take a look at the raw source of the email and update your post with the structure you're seeing? There will be an initial mime type set in the header. it will look something like this:
Mime-Version: 1.0
Content-Type: multipart/mixed;
boundary="--==_mimepart_50596418be947_c7223fec9d834d3874256";
charset=UTF-8
Content-Transfer-Encoding: 7bit
This says the parts to follow are not alternative versions of the same information, but instead instruct the email client to display them distinctly.
Later on in the email, your text and html parts should proceeded by something like:
----==_mimepart_50596418be947_c7223fec9d834d3874256
Date: Wed, 19 Sep 2012 06:20:12 +0000
Mime-Version: 1.0
Content-Type: multipart/alternative;
boundary="--==_mimepart_50596418be468_c7223fec9d834d38741a5";
charset=UTF-8
Content-Transfer-Encoding: 7bit
And finally, the encoded pdf part should have a mime header like:
----==_mimepart_50596418be947_c7223fec9d834d3874256
Date: Wed, 19 Sep 2012 06:20:12 +0000
Mime-Version: 1.0
Content-Type: application/pdf;
charset=UTF-8;
filename=terms.pdf
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename=terms.pdf
With a simple test email I just sent to myself with text, html parts, and a large pdf, I can view the email on my iphone. It shows the html part and an icon that lets me download the pdf.
Some e-mail clients may require an e-mail to have a plain text part in order to display it correctly.
I just ran into this message while converting a Rails app from 2.3 to 3.2. I thought I converted my mailer correctly, but the old version specified content_type: "multipart/mixed" in the options. However, when I removed that, I received the attachments and the HTML and plain-text rendered correctly. I think that having that setting in there overrode whatever Rails does to put in different types of content, which was not what I wanted. Thanks to the original answer for leading me in that direction.
