</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
Test body]]>

Multipart email with ical attachment displays incorrectly

I'm not sure if this is an issue with my code, ActionMailer, Mail, or maybe even the icalendar gem?
A user registers for an event and they get an email with an ical attachment:
# app/mailers/registration_mailer.rb
class RegistrationMailer < ApplicationMailer
helper MailerHelper
def created(registration)
...
cal = Icalendar::Calendar.new
cal.event do |e|
e.dtstart = #event.start_time
e.dtend = #event.end_time
e.organizer = 'mailto:filterbuilds#20liters.org'
e.attendee = #recipient
e.location = #location.addr_one_liner
e.summary = #summary
e.description = #description
end
cal.append_custom_property('METHOD', 'REQUEST')
mail.attachments[#attachment_title] = { mime_type: 'text/calendar', content: cal.to_ical }
mail(to: #recipient.email, subject: "[20 Liters] You registered for a filter build on #{#event.mailer_time}")
end
...
end
I have text and HTML views:
app/views/registration_mailer/created.text.erb
app/views/registration_mailer/created.html.erb
When I omit the attachment, the email is structured like this:
Header stuff...
Mime-Version: 1.0
Content-Type: multipart/alternative; boundary="--==_mimepart_63358693571_1146901122e"; charset=UTF-8

It's a weird tree suddenly:
1. Content-Type: multipart/mixed
A. Content-Type: text/plain
B. Content-Type: text/html
C. Content-Type: multipart/alternative
i. Content-Type: text/plain
ii. Content-Type: text/html
D. Content-Type: text/calendar
Rails' mailer preview doesn't reproduce this issue, nor does using Litmus' email client previews (because it seems to remove the text part and attachments), but I'm assuming with the deformed structure of content-types this isn't just a client-specific rendering issue.
I'm thinking this is coming from the Mail gem underneath ActionMailer structuring the content-types oddly, but I'm a bit out of my depth here. It could be ActionMailer, I really don't know how to tell.
I'm not very well versed in this, but I think I want this structure:
1. Content-Type: multipart/mixed
A. Content-Type: multipart/alternative
i. Content-Type: text/plain
ii. Content-Type: text/html
B. Content-Type: text/calendar
So, two questions:
1. If it's my code, what am I doing wrong?
2. If it's not my code, can I force the structure I want?
I've been combing through ActionMailer and Mail code bases, but haven't found a way to manually form my email to this level.
After more digging, I'm blaming ActionMailer, though I'm still not sure why text and html parts are getting added twice.
A monkey patch for my specific use was to let ActionMailer and Mail build the mail object and then just manually remove the unwanted parts:
# app/mailers/registration_mailer.rb
...
mail.attachments[#attachment_title] = { mime_type: 'text/calendar', content: cal.to_ical }
mail(to: #recipient.email, subject: "[20 Liters] You registered for a filter build on #{#event.mailer_time}")
# PATCH: text and html parts are getting inserted in multipart/mixed (top level) as well as multipart/alternative (2nd level)
mail.parts.reject! { |part| !part.attachment? && !part.multipart? }
This only works for my specific case. If the nesting that mail creates for you is different, your reject! statement will need to be different.
In my case, mail builds this structure:
1. Content-Type: multipart/mixed
A. Content-Type: text/plain
B. Content-Type: text/html
C. Content-Type: multipart/alternative
i. Content-Type: text/plain
ii. Content-Type: text/html
D. Content-Type: text/calendar
So I step into the first level (A. - D.) and reject any parts that are not multipart and not an attachment:
1. Content-Type: multipart/mixed
A. Content-Type: text/plain <-- not multipart, not attachment = rejected
B. Content-Type: text/html <-- not multipart, not attachment = rejected
C. Content-Type: multipart/alternative <-- is multipart, not attachment = kept
i. Content-Type: text/plain
ii. Content-Type: text/html
D. Content-Type: text/calendar <-- not multipart, is attachment = kept
If you are facing this issue, I recommend you use a debugger to inspect your mail object, specifically focusing on the parts. Keep in mind that parts can be deeply nested.
Mail::Part inherits from Mail::Message which has some helpful methods you can use to determine the "shape" of your message:
multipart?
attachment?
attachments
has_attachments?
boundary
parts
all_parts
And good luck.

MS Graph API 4MB size limit with MIME

It seems the MS REST (EWS) services are being deprecated toward the end of 2022 and moving to graph api is recommended.
All good, graph works just fine...except for the 4MB size limit on the payload!
Ok so there is this: https://learn.microsoft.com/en-us/graph/outlook-large-attachments?tabs=http
What a mare! But anyway I am posting MIME content as below:
https://learn.microsoft.com/en-us/graph/outlook-send-mime-message
ie. I'm posting plain text content like below to graph's sendMail endpoint
From: Some One <someone#example.com>
MIME-Version: 1.0
Content-Type: multipart/mixed;
boundary="XXXXboundary text"
Subject: This is a test
This is a multipart message in MIME format.
--XXXXboundary text
Content-Type: text/plain
this is the body text
--XXXXboundary text
Content-Type: text/plain;
Content-Disposition: attachment;
filename="test.txt"
this is the attachment text
--XXXXboundary text--
I don't understand how this would work with the upload-session aproach - so is it possible, and if so, how, can I send MIME content > 4MB using the graph api?

multipart/mixed MIME creation for amazon SES on iOS

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.

English Email Displays Chinese-like Characters

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
Date: 17 Apr 2013 22:11:25 -0700
Subject: Some Subject
Content-Type: multipart/alternative;

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.

send mail with doc file attachment

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">
person name: <input type="text" name="person_name" >
<br />
Attachment : <input id="attachment_file" class="field" style="height: 25px;" type="file" name="attachment_file_name" />
<input id="submit_button" type="submit" value="Send" />
</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
