Any thoughts how to fix or check it?
--------------------------------------------------------------------------------
Could you please post the most simple / light test mail which fail to be processed by Redmine so that the issue can be reproduced it easily ?
--------------------------------------------------------------------------------
Sure. This are 2 msg files of the message: one just in Unicode format.
--------------------------------------------------------------------------------
Unfortunately, outlook doesn't have built-in capabilities for saving emails as emls.
I've converted the email to eml format with some external tool. I'm not sure if it is the same content as processed by the receiver (We use "rake redmine:email:receive_pop3" approach). Is there any way to catch exactly the same content? (Say, extended information in log or something else)
--------------------------------------------------------------------------------
Hi, any update about the issue?
Can I help with it?
--------------------------------------------------------------------------------
Actually, it's a duplicate of #5994 but I keep it open since there is more details.
--------------------------------------------------------------------------------
I spent half the day learning ruby so I could fix this today. So I have uploaded the patch that I came up with for Redmine 1.3.3 but I made this patch to work with the latest in the git repo.

It's really simple because Tmail has already converted the attachment object to EML and saves it to Redmine as "noname" so windows cannot open the file, I tried manually opening it with outlook and adding .msg to the file but no go. Then I looked up the code where it is saving the attachments and made it write it directly to the file system, then I found that it is already an EML. So all this patch does is if the attachment meets the 'message/rfc822' content type requirement then I name the file attachment.eml before it saves it to Redmine. I have also tried sending attachments inside an email attached as an attachment and it all comes through fine.

The patch is for app/models/mail_handler.rb.
--------------------------------------------------------------------------------
Unfortunately, that doesn't help in any way. After some tests we discovered that the internal email in this case doesn't look like attachement at least system think so.
We used this code for check (mail_handler.rb)
--------------
def add_attachments(obj)
if email.has_attachments?
email.attachments.each_with_index do |attachment, i|
print "attachment.content_type = "
print attachment.content_type

--------------
and there wasn't any output like attachment.content_type = smth

I should also say that in our case there is no noname file in Redmine after email was processed.

To sum that, I think the problem is that ruby mechanisms can't understand the structure of such kind of emails. And that is very sad.

Looking forward to hearing from you, Joel.
--------------------------------------------------------------------------------
Hmm, interesting.

I'm afraid I cannot help with that one, as the attachments are coming through but Redmine just didn't know how to handle them.

Keep in mind I am using 1.3.3 here, and Redmine uses "Tmail":http://tmail.rubyforge.org/ for the mail handling.

So you are using an older version which cannot handle the Outlook .msg files at all?
--------------------------------------------------------------------------------
As I said we are using Redmine 1.1.2. May be there is a simple script which we can use for discovering our issues nature?

Hi! Finally we've been able to deal with this issue. The problem was this kind of attachments in emails generated by outlook was stored not like attachment but as part of multipart message with the following header

------=_NextPart_000_01C9_01CDF973.EB5E8D50
Content-Type: message/rfc822
Content-Transfer-Encoding: 7bit
Content-Disposition: attachment

We've created special patch for this case (attached)

I'm not an expert in ruby so that is obvoisly not a state of the art piece of code and I would be honored if someone would rewrite this to follow ruby, RoR, and Redmine guidelines.
Also that would be great if this code after revision will be added in Redmine core.

--------------------------------------------------------------------------------
Bug still exists, checked on 2.3.1 stable, solution above doesn't work, any ideas how to fix it ?

Thank you.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
I've just made a quick test with the attached sample email @This_is_an_issue_title.eml@ and it works fine. The issue is created with the test email as attachment, see below. Could you attach the content of your email for which it doesn't work?

!issue.png!
--------------------------------------------------------------------------------
I just ran in the same error. After analyzing:

It is not a question which attachment you attach. The Question is how.
Look at the raw text of your Mails. If you attach with this, the attachment is ignored by redmine.

<pre>
--GPJrCs/72TxItFYR
Content-Type: message/rfc822
Content-Disposition: inline
Content-Transfer-Encoding: 8bit

Return-path: <bla@nix>
[...some mail...]
</pre>

If you use this (with a name option), the attachment will be attached to your ticket.
<pre>
--GPJrCs/72TxItFYR
Content-Type: message/rfc822
name="withname.eml"
Content-Disposition: inline
Content-Transfer-Encoding: 8bit

Return-path: <bla@nix>
[...some mail...]
</pre>

my Details:
Redmine version 2.5.2.stable
Ruby version 1.9.3-p194 (2012-04-20) [x86_64-linux]

--------------------------------------------------------------------------------
Sergeys patch worked for me with a minor change, because part.content_disposition does not just contain "attachment" but a longer string...

Example:
@#<Mail::Part:32266040, Multipart: false, Headers: <Content-Type: message/rfc822>, <Content-Transfer-Encoding: 7bit>, <Content-Disposition: attachment; creation-date="Thu, 16 Apr 2015 07:32:25 GMT"; modification-date="Thu, 16 Apr 2015 07:32:25 GMT">>@

This is the modified block from Sergeys patch:

<pre>
logger.info "Checking multipart"
if email.parts
email.parts.each do |part|
p part.content_disposition
if part.content_disposition =~ /attachment/i
logger.info "Found email attachment in parts section"
contents = part.decoded.gsub(0x0a.chr, 0x0d.chr+0x0a.chr) # this is to change newline type in attachment
logger.info "Trying to parse it as email"
attachment_email = Mail.new(contents)
p attachment_email
obj.attachments << Attachment.create(:container => obj,
:file => contents,
:filename => attachment_email.subject + ".eml",
:author => user,
:content_type => part.content_type)
logger.info "Attachment added"
end
end
end
logger.info "Attachements added"
</pre>

I think it should be fixed by mail gem.

For what it is worth, I don't think this has ever worked for us.

Every 'Forward as Attachment' email that Redmine has touched only had the body text included in the resulting issue, not the attachments. We use Microsoft Exchange as the mail server and Microsoft Outlook as the email client. The oldest version we have installed is Outlook 2010, but later installations are all 2016. We've tested with Outlook 2010, 2013 and 2016, all with the same results.

We generally run the latest Redmine release version. Details for our installation:
