Hi Daniel,

Here is the answer to your questions:
Does your code fail against all HTTPS servers you try it against?
Dushyant >> Yes it has failed against all exchange 2010 servers I have tried in my lab.
How much data has it managed to send by the time it stops due to timeout?
Dushyant >> Do not know how can i calculate it.
Can you actually send 4.9MB successfully? How long time does that take?
Dushyant >> I actually tried to send a 4.76 MB and it took just 1 second with 7.23.1 curl.
           Even for larger data 5MB in working scenario it takes the same time.

           Time Before Easy perform 2014-12-21.04:20:27
           Time after Easy perform 2014-12-21.04:20:28

Meanwhile I am creating a target server that will be accessible to you so that you can debug with your own set of tools.

Just to add to Florian's Problem.

For me issue is occurring for both NTLM with HTTPS and BASIC with HTTPS.

@Florian : you can verify this by changing your authentication mode to be BASIC with HTTPS
           for me its reproducible for both.

Thanks
Dushyant

** [bugs:#1460] Longer Voice Message not being posted to Exchange Server with curl release version >=7.24 using SSL(https)**

Hi Team,
With reference to the following query:
http://curl.haxx.se/mail/lib-2014-12/0011.html
I have written a sample client as a proof of concept that does the POST request for sending a voice message of 5MB.
My application works fine with curl version 7.23.1 while it does not work with 7.24 version.
I have even tried with latest curl version 7.39 but problem is still reproducible.
Attached is sample application code along with 32 bit executable.
Three files are attached in sample_client.zip.
(1) curl-client.cpp
(2) sconstruct   ( sort of makefile )
(3) SampleClient  : ELF 32-bit LSB executable
   Only thing you need is to have 32 bit compiled curl i.e. libcurl.so.4  placed at any Linux box at path /root/
   Try it with different curl versions 7.23.1(works fine) and 7.39 (doesn't work)
 Command Line Arguement for this File
 argv[1] --> Exchange server(2007)  hostname                   :     https://<<hostname>>
 argv[2] --> UserSMTPaddress with Mailbox on Exchange  :     some_user_at_hostname.com
 argv[3] --> PassWord                                                     :     domain\admin:password
  
  How to run:
 ./SampleClient https://hostname.com some_user@hostname.com domain\\admin:password
Here is the Log enabled output for the post request with curl 7.24 ,it just times-out
