Do I have built – in email client like Outlook Express or other in Windows 2008 server which I to use for test ?

Hi experts!

I have a dedicated Windows 2008 Server 32 bit from godaddy.com
I have a problem sending email from my ASP.NET application. My code is correct, I upload same this site in other server (again Windows 2008 Server) and all is function at 100 %

 So I suspect that godaddy has some limit because of spam email. I write to him, however, I want to make better test to locate the problem.

SO I want to install Email client on this server and to try to tune same email and to try. This will show exatly that problem is in network connection, I’m 90 % sure, but first answer of godaddy is that there is error with my code.
Error which I get with my code is:

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 68.178.232.62:25

[SocketException (0x274c): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 68.178.232.62:25]

   System.Net.Mail.SmtpClient.Send(MailMessage message) +1213


 For every case I open port 25 in Windows, but I still get same error.

 So question is: do I have built – in email client  like Outlook Express or other in Windows 2008 server which I to use for test ? I want to not use external program, to install it and then to remove it .. I know that remove is always not at 100 % back all .

Or, if i have no other options - which email client to install ?
