Defect #5784
closed
Mail subject is cutting on MS Exchange 2007, 2010 after 256 character. (RFC2047)
0%
Description
Redmine - does not follow the RFC2047, as the line should not be longer than 75 character.
The following example shows how a large line should be:
Content-Type: text/plain; name=
"=?iso-2022-jp?B?GyRCJCIkJCQmJCgkKiQrJC0kLyQxJDMkNSQ3JDkkOyQ9JD8bKEI=?=
=?iso-2022-jp?B?GyRCJEEkRCRGJEgkSiRLJEwkTSROJE8kUiRVJFgkWyReJF8bKEI=?=
=?iso-2022-jp?B?GyRCJGAkYSRiJGQkZiRoJGkkaiRrJGwkbSRvJHIkcyMxIzIbKEI=?=
=?iso-2022-jp?B?GyRCIzMjNCM1IzYjNyM4IzkjMBsoQi50eHQ=?="
The following RFC describe how the message header should be for Non-ASCII Text
MIME (Multipurpose Internet Mail Extensions) Part Three: Message Header Extensions for Non-ASCII Text
http://www.faqs.org/rfcs/rfc2047.html
encoded-word = "=?" charset "?" encoding "?" encoded-text "?="
Example for Error.
Initial data:
- Sender's mail client - from Redmine.
!!==> Subject: contains 81 (!!!) character in Russian encoding.
This was only the letters without any characters, spaces, digits, etc.
- Recipient's mail client: OLK 2007 (12.0.6316.5000) SP1.
- Mailbox server: Exchange 2007 SP1
!!==> Field Subject shows CORRECTLY in Outlook 2007.
Subject: =?koi8-r?Q?=C6=CC=C4=C4=D0=C1=CF=CC=C4=C1=D7=D0=DB=DD=C5=CB=D6=C4=CD=D9=D7=CF=D0=DA=DD=D5=CB=C4=D9=CC=D7=CF=D0=CC=C1=D0=CF=C4=CC=D7=C1=CF=C4=CC=D9=D7=CF=C1=DB=DD=D5=C1=CF=D7=D9=C4=C1=CC=CF=CB=D5=C3=C4=DB=C1=C4=CC=D0=D2=CC=C1=CF=D0=D5=C3=C4=CB=CF=DB=C9?=

- Status changed from New to Resolved
- You can change this limitation up to 4096 symbols.
On exchange server you should do the following:
- cd in bin directory of exchange installation path
- open file EdgeTransport.exe.config with notepad
<configuration> <runtime> <gcServer enabled="true" /> </runtime> <appSettings> <add key="AgentLogEnabled" value="true" /> <add key="ResolverRetryInterval" value="30" /> . . . . . . </configuration>
- Add this lines between "<configuration>" and "<runtime>"(don't change the "version" field value):
<configSections> <section name="CTS" type="Microsoft.Exchange.Data.Internal.CtsConfigurationSection, Microsoft.Exchange.Data.Common, PublicKeyToken=31bf3856ad364e35, version=8.0.681.0, culture=neutral"/> </configSections> <CTS> <MimeLimits> <MaximumEncodedWordLength Value="4096"/> </MimeLimits> </CTS>
- Restart Exchange Transport Service
BTW, this is not redmine's defect, this is feature of exchange. Be careful when submitting bugs.
The same in russian:
Redmine отсылает разные уведомления по почте.
Заголовок Subject в случае наличия не ASCII символов(русских букв) кодируется при отправке в utf-8.
Почтовые клиенты понимают это и отображают по-русски.
Тема обрезается до 255 символов, почтовый клиент не видит "?=" в конце строки и не декодирует ее.
- Чтобы увеличить длину заголовков до 4096:
- Перейдите в каталог bin где у вас установлен Exchange
- Откройте в блокноте EdgeTransport.exe.config
<configuration> <runtime> <gcServer enabled="true" /> </runtime> <appSettings> <add key="AgentLogEnabled" value="true" /> <add key="ResolverRetryInterval" value="30" /> . . . . . . </configuration>
- Добавьте эти строчки между <configuration> и <runtime> (поле "version" менять не надо) :
<configSections> <section name="CTS" type="Microsoft.Exchange.Data.Internal.CtsConfigurationSection, Microsoft.Exchange.Data.Common, PublicKeyToken=31bf3856ad364e35, version=8.0.681.0, culture=neutral"/> </configSections> <CTS> <MimeLimits> <MaximumEncodedWordLength Value="4096"/> </MimeLimits> </CTS>
- перезапустите службу Exchange Transport Service.
И вообще, это не баг redmine, а фича exchange.

- Status changed from Resolved to Closed
- Resolution set to Invalid
Closing as being a "feature" of exchange, not a bug of redmine (in any case, redmine uses the mail handling libraries provided by ruby and/or rails, so any error would have to be reported there rather than here).
Roland, thanks for what looks like a good explanation :-)

Я столкнулся с похожей проблемой, при создании задачи с темой более 12 русских символов на почту приходят такие вещи (=?utf-8?Q?=5B=D0=A2=D0=95=D0=A1=D0=A2=D0=A2=D0=95=D0=A1=D0=A2_=D0=A2=D0=95=D0=A1=D0=A2_=2D_=D0=9E=D1=88=D0=B8=D0=B1=D0=BA=D0=B0_=23=31=36=5D_=28=D0=9D=D0=BE=D0=B2=D0=B0=D1=8F=29_=D0=B2=D0=B0_=D0=B2=D0=B0_=D0=B2=D0=B0_=D0=B2=D0=B0_=D0=B2=D0=B0_=D0=B2=D...)_
если меньше или 12 то все нормально ([ТЕСТ ТЕСТ ТЕСТ - Ошибка #17] (Новая) ва ва ва ва )
непонимаю что нужно сделать что бы все было нормально
