gzip injection fails using webdav   

hi,

We are facing problem with injecting compressed (gzip) mail items. We are 
trying with Exchange 2003....
We configured our mail server’s IIS to support compression of .EML files.

http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/502ef631-3695-4616-b268-cbe7cf1351ce.mspx?mfr=true

And our extraction works fine with extracting mail items in compressed form.
We are using “Accept-Encoding” header with value “gzip, deflate” along with 
“GET” method.
But when we try to inject the compressed stream to a 2k3/2k7 mailbox using 
“PUT” method, we are getting blank mail item. Actual mail is not getting 
injected.
We tried with following approaches along with PUT method:
1.“Accept-Encoding” header with value “gzip, deflate”. 
2.“Content-Encoding” header with value “gzip”. 
3.Setting the AutomaticDecompression property of HttpWebRequest to 
4.DecompressionMethods.Gzip. 
5.Setting the Content-Type of the HttpWebRequest to “message/rfc822”, 
“application/x-compressed”, “application/x-zip-compressed”, 
“application/x-gzip-compressed” and “application/octet-stream”. 
 
Are we missing something else? Please help us!!!
