Then everything works good. I cannot find the fake domain expressed anywhere during runtime so.. I'm inclined to just use this hack. Does anyone know of any downsides?

I'm implementing an .eml parser using Javamail 1.5.6, I've started copying from msghow.java a sample provided within javamail.
I'm testing an eml which contains as attachment another eml, this is an extract:

Javamail recognizes that eml but when I get its subject, date, body, attachments and so on, they all are null.
msghow.java itself doesn't see them.
Before javamail I implemented my parser with mime4j and I haven't this problem, but now I would like to parse emls using only javamail if possible
From the javadocs describing the mail.mime.allowencodedmessages property:
The MIME spec does not allow body parts of type message/* to be encoded. The Content-Transfer-Encoding header is ignored in this case. Some versions of Microsoft Outlook will incorrectly encode message attachments. Setting this System property to "true" will cause the Content-Transfer-Encoding header to be honored for message attachments. The default value of this property is false.
I really need your help!
I want to send a reply message with the Gmail REST API. Using the standard url:
https://www.googleapis.com/gmail/v1/users/userId/messages/send, everything works fine. By sending the raw data of the message and the thread id, the new message is attached to the same thread.
Now as I want our customers to be able to upload bigger attachments i use the upload url: https://www.googleapis.com/upload/gmail/v1/users/userId/messages/send?uploadType=media.
I send the request with Content-Type set to message/rfc822 as set in the documentation, but I can't find a way to send also the Thread id.
I tried adding it as a header (example: Thread-Id) to the MimeMessage, but it only works when i send the message to Outlook - there the message is sent to the same thread.
I have also populated the In-Reply-To header, the References header and the Subject is the same as in the original thread with additional 'Re:'. Gmail still creates a new thread for this message.
Update:
I have tried using the upload uri with parameter uploadType=multipart and here is my request:
Content-Type: multipart/related; boundary="=-EEoaSdATsa0it8EbymRVdg=="

But API returns an error which states that multipart/related is not an allowed content type.
I am using the c version of the gmime library and having problems parsing and extracting content that seems to be already in multipart form. I thought parsing content as is gmime will figure out how to construct the multipart correctly so that simply performing
g_mime_multipart_get_part(mimeMessage, 0)
will return the soap-xml part. Clearly I'm wrong and my limited understanding of mime and gmime library is killing me. Please assist. Thanking you in advance.
GMimeStream * mimeStream = g_mime_stream_mem_new_with_buffer(incoming, n);
GMimeParser * mimeParser = g_mime_parser_new_with_stream(mimeStream);
g_object_unref(mimeStream);
GMimeMessage * mimeMessage = g_mime_parser_construct_message(mimeParser);
g_object_unref(mimeParser);

GMime can't parse that because it's incomplete. How can the parser know what the multiparty boundary is if the content doesn't start with a Content-Type header that defines the boundary?
I got this issue with icalendar, it doesn't show the attachment and the confirmation button when sent to gmail,yahoo, aoutlook.com.
it was working before without html message and multipart/mixed header.
now when i recieve the email it only show me the the text of the calendar, it doesn't recognize it.

thanks in advance.
Well your second body part has 2 content-type headers:
Content-Type: application/ics; name="Rv-invite.ics"
Content-Disposition: attachment; filename="Rv-invite.ics"
Content-Transfer-Encoding: base64
and
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: 8bit
It looks like some of the headers also belong to the top level and not in the body part:

See also this post about the correct MIME structure to use in general: Multipart email with text and calendar: Outlook doesn't recognize ics
I am writing an app that decrypts encrypted emails for a client.
The encrypted data is in the form of an email attachment, which, when decrypted, looks like this :
Content-Type: multipart/mixed;
boundary="PGP_Universal_830ECF7A_AFB087B4_241DE401_9BE7FFD1"
--PGP_Universal_830ECF7A_AFB087B4_241DE401_9BE7FFD1
Content-Type: multipart/alternative;

I am writing the app in Cascades. As I cannot find a native way of transforming this data into an email, to let the email client deal with the attached base64-encoded file and so on, I am hoping to find a C++ class (it can optionally depend upon Qt, obviously) that I can use on the BB10 which can parse these kind of multipart messages.
It is possible to get SPMIME to compile on BB10. It is LGPL so it might need to be compiled seperately and linked to if your app is not GPL.
