Send Email in Umbraco

I am setting up a function to send out mails(as confirmation for orders but thats a later matter).

Problem is that the mails are to be sent from the companys exchange server and so far all i have gotten is connection failed.

I am in communication with the server tech trying to find out whats wrong, and since its been a while since i set up email(on the cms side) i might be making a stupid mistake, so maybe somebody here will catch it :)

web.config: (port number specified by server tech)

(all info replaced with generic but consistent names for safety ofc)

<system.net>
<mailSettings>
    <smtp from="info@mydomain.com">
        <network host="smtp.ourexchangeserver.dk" userName="info@mydomain.com" password="secret" port="26" />
    </smtp>
</mailSettings>

razor script test:

      @{
    try {
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.To.Add("myadress@gmail.com");
message.Subject = "This is the Subject line";
message.From = new System.Net.Mail.MailAddress("info@mydomain.com");

message.Body = "This is the message body";
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient();
smtp.Send(message);
    }
    catch(Exception ex)
            {
               <p> error: <br/> @ex.ToString() </p> 
            }
}

Error caught in exception:

 System.Net.Mail.SmtpException: Failure sending mail. --->
 System.Net.WebException: Unable to connect to the remote server --->
 System.Net.Sockets.SocketException: 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

Thank you in advance.
