MOSS Search for emails and attachments context

Some of our customers requested to have the ability to search context within email messages and within its attachments.

Searching the web for a solution came with results that indicate that a third-party development is needed to achieve this ability...
Then I found Gavin Adams post and Tom Vandaele post that wrote that the ability to deep search within msg files is a MOSS out-of-the-box option that need to be configure.

Followed their instructions I tried to search context in a docx file attachment with in a msg file that was uploaded to a document library. I succeed to get the msg file by searching its context , but failed to get results related to the email's attachments.

After some tests of my own, I figure out that the registry should look like that:

1. Make sure that this key exists in the MOSS registry
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server\12.0\Search\Setup\ContentIndexCommon\Filters\Extension\.msg
2. Add these keys and values to the .msg
   “Extension”=”msg”
   “FileTypeBucket”=dword:00000001
   “MimeTypes”=”application/msoutlook”

The MimeTypes application/msoutlook is the one I use to gain the deep search ability (couldn't do it using the MimeTypes = application/vnd.ms-outlook)

A note to those of you using hebrew documents, I checked it and it's working for hebrew attachments as well.
