I am trying to use the Groupwise email, in my web application.

And use below configuration to create an smtp client ( this SMTP class is from dot net framework).

SmtpClient objMail = new SmtpClient("");
objMail.Port = int.Parse("25");
objMail.UseDefaultCredentials = false;
objMail.EnableSsl = true;
objMail.DeliveryMethod = SmtpDeliveryMethod.Network;
objMail.Credentials = new System.Net.NetworkCredential("MyWebclientUserName" , "MyWebclientPassword");

I am unable to send email using this configuration. Do i need to add additional parameters ? or Do I need to use any NovellGroupWise Libraries??

(Same configuration work for Gmail account, with respective gmail settings).

Please let us know.
