LO45329: MIME TYPE AND SUBTYPE FOR A ATTACHMENT FILE IS NOT ASSOCIATED CO RRECTLY WHEN ATTACHING A FILE FROM NOTES CLIENT

APAR status

• Closed as fixed if next.

Error description

• When attaching a files to a message in MIME format, Notes Client
  determines
  MIME Type and subtype according to a table stored in Notes
  Client.
  Notes client does not working as Lotus Domino Administrator 6
  Help describes.
  
  Below is the excerpt from "Mapping MIME types to file
  extensions" in "Lotus
  Domino Administrator 6 Help"
  ---------
  Content-type header for the message part that describes the
  attachment.
  When a Notes client attaches a file to a message it sends in
  MIME format (for
  example, when sending to Internet recipients or to Notes mail
  recipients whose
  mail storage preference is set to MIME), the client first checks
  the operating
  system to determine what file associations are defined. Clients
  running on
  Microsoft Windows check the Windows registry, while clients
  running on the
  Macintosh check Internet Config. If the client cannot locate
  MIME type
  information from these sources, it then checks the Domino
  Directory for a File
  Identification document that applies to files with the same
  extension as the
  attached file. After locating the correct document, the client
  places the MIME
  type and subtype information from the document in the MIME
  header describing
  the attachment.

  additional information
  -->
  
  Steps to reproduce this problem
  
  1. Set up Notes Client
  2. Register a new user whose mail storage preference is MIME
  3. Create a mail message <- who create a message?  mime user or
  non-mime user?
  4. Input some text and attach a pdf file, send the message <-
  send a message to
  whom?  mime user or non-mime user?
  5. Switch user ID to the recipient and open the message
  6. From menu, select [View] - [View] - [Page Source] <- I don't
  see any menu
  like this. [View] - [Page Source] how did you get this menu in
  Notes client?
  7. Content-Type for pdf file is "application/octet-stream", not
  
  "application/pdf".

  -------
  
  - Acrobat reader is installed in the machine which Notes Client
  running. In
  Windows registry, the extension .pdf is registered.
  - In "File Identification" View of Domino Directory, the File
  Identification
  document for ".pdf" exists.
  
  Notes Client determines the MIME type and subtype in the
  following order.
  It seems that this is done in function MimeGetTypeInfoFromExt in
  
  mime\mimetyps.cpp.
  
  1. Windows registry
  2. File Identification document in Domino Directory
  3. A table stored in Notes Client.
  
  1. Windows registry
  Function : clientMimeGetTypeInfo
  Notes Client checks the registry "REGKEY_MIME_MAP".
  REGKEY_MIME_MAP is defined in mime\mimetyps.cpp as following.
  #define
  "SYSTEM\\CurrentControlSet\\Services\\InetInfo\\Parameters\\Mime
  Map"
  
  This registry key does not exist in my Windows 2000/NT box.
  
  2. File Identification document in Domino Directory
  Function : serverMimeGetTypeInfo
  This function only checks names.nsf in local, not Domino
  Directory.
  I copied "($FileIdentification)" view and File Identification
  documents from
  Domino Directory to names.nsf on local.
  Mime type and subtype changed to "application/pdf" from
  "application/octet-stream".
  
  3. A table stored in Notes Client.
  Function : MimeFileTypeImpl::fallback_MimeGetTypeInfo
  This function uses a table stored in Notes Client.
  SPR TOI4YRHJV explains about this table.
  
  SPR TOI4YRHJV:  MS-Excel spreadsheet files not associated with
  the right MIME
  Subtype
  
  When attaching a file in Mime message in Notes Client, Notes
  Client fails to
  get the information from Windows registry and local names.nsf.
  MIME type and subtype is determined only from a table stored in
  Notes Client.
  

Local fix

• Copy "($FileIdentification)" view and File Identification
  documents from Domino
  Directory to names.nsf on local.
