~# ruby -v
ruby 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]

Redmine version: == 2012-06-05 v2.0.2

Today I had another incoming email, which broke email subject. I noticed, that on some e-mail clients issue subject was readable, but with different encoding.
In message source Subject was set to: =?UTF-8?Q?[*_ien=C4=81ko=C5=A1ie_e-pasti]_#287_-_Apm=E2c=EEbu?=
=?UTF-8?Q?_materi=E2ls_darbam_ar_jauno_webserveri?=

Anyway - another task with incoming attachemtn
Rake task result (notice warning: Non US-ASCII detected and no charset defined.
Defaulting to UTF-8, set your own if this is incorrect.):

#4 Updated by Arnis Juraga over 5 years ago

Still, the same problems!
I can see, there are some problems with encoding, charsets?
When e-mail has been read, the message Subject, for example, is incorrectly rewritten. I can see in Message source:

ORIGINAL MESSAGE AS ON MAIL SERVER:
Subject: =?windows-1257?Q?sinhroniz=E2cija?=

Email, sent by REDMINE:
Subject: =?UTF-8?Q?[*_ien=C4=81ko=C5=A1ie_e-pasti]_#266_-_sinhroniz=E2cija?=

Can it be fixed in config files?

#5 Updated by Arnis Juraga over 5 years ago

Also, after incoming email has been read in, Redmine saves "truncated" message suject, for example:
Incoming message with subject: "sinhronizācija"
is created as issue with subject: "sinhroniz"

#6 Updated by Andre Rodier over 5 years ago

I confirm that I have the same issue.

My email contain my name (André) in the signature, and the imap importation fail:

However, if I remove my name, it's working...

#7 Updated by Bjarni Thorisson over 5 years ago

I have the same problem.

To reproduce, log into a gmail account. Go to settings, on the first tab (General) make sure the "Outgoing message encoding" is set to "Use default text encoding for outgoing messages"

Then send an email containing non ASCII letters, for example ú æ í þ ð.

It will not turn into a ticket, the error I get is:

If you then try setting the "Outgoing message encoding" to utf8 it works again.

This obviously means I can only accept email from people with their email client set to utf8, if they use special characters.

#8 Updated by Bjarni Thorisson over 5 years ago

I fixed it, this only blew up if the subject contained special characters.

in mail_handler.rb I changed the receive_issue function:

  def receive_issue
    project = target_project
    # check permission
    unless @@handler_options[:no_permission_check]
      raise UnauthorizedAction unless user.allowed_to?(:add_issues, project)
    end

    issue = Issue.new(:author => user, :project => project)
    issue.safe_attributes = issue_attributes_from_keywords(issue)
    issue.safe_attributes = {'custom_field_values' => custom_field_values_from_keywords(issue)}

    # CHANGED THE FOLLOWING FOUR LINES:
    body_part = email.text_part || email.html_part || email
    subj = email.subject
    subj = Redmine::CodesetUtil.to_utf8(subj, body_part.charset)
    issue.subject = subj.chomp[0,255]

    if issue.subject.blank?
      issue.subject = '(no subject)'
    end
    issue.description = cleaned_up_text_body

    # add To and Cc as watchers before saving so the watchers can reply to Redmine
    add_watchers(issue)
    issue.save!
    add_attachments(issue)
    logger.info "MailHandler: issue ##{issue.id} created by #{user}" if logger && logger.info
    issue
  end

As I am not a ruby programmer I'm sure this could be done in a more elegant way. The main thing is to make sure that the subject is also converted to utf8, you can check its' current encoding by checking the encoding of the body.

BTW: I'm guessing something similar has to be done for txt attachments

#10 Updated by Steffen Zieger over 4 years ago

As time is problematic right now, I can't promise it, but I'll do my best.

Attached is a patch, which fixes this issue in attachments, too.
Maybe there is a better way, but at least it's working for me.

#14 Updated by Toshi MARUYAMA over 4 years ago

  • Category set to Email receiving

#15 Updated by Bernd Köster over 4 years ago

Are there any reasons that these patches are not set for the 2.3.3 version? Can I help out?

Because this issue patches have no tests.

#17 Updated by Arnis Juraga about 4 years ago

And still - problem persists in the latest Redmine version as well.

Can I do tests, to verify fix?

#18 Updated by Aníbal Pacheco about 3 years ago

I got the same warning by email from cron. :( using redmine 2.6.0

#19 Updated by Arnis Juraga about 3 years ago

Look at mine Redmine/Rails/Gems version, may be upgrade can help for You?

I cannot reproduce it today anymore, with the same old file I have attached myself,

Imap read script:

#!/bin/bash
export GEM_HOME=/var/lib/gems/1.9.1/gems/
export PATH=/var/lib/gems/1.9.1/bin:$PATH
RAILS_ENV=production
dirpath="/opt/redmine/redmine-ri-2.6.0" 
cd $dirpath

/usr/local/bin/rake -f $dirpath/Rakefile redmine:email:receive_imap RAILS_ENV="production" host=imap.gmail.com ssl=SSL \
port=993 username=support@DOMAIN password=PASSWORD move_on_success=izlasitie \
move_on_failure=failed project=incoming unknown_user=create no_permission_check=1 no_account_notice=1 --trace

Email was received and added to Redmine correctly now!!!

And received ouput:

** Invoke redmine:email:receive_imap (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute redmine:email:receive_imap
