+Bug#: 82035
+Product: Mono: Class Libraries
+Version: 1.2
+OS Details: Ubuntu (edgy I believe)
+Status: NEW   
+Priority: Normal
+Component: System
+AssignedTo: mono-bugs at ximian.com

+TargetMilestone: ---
+Summary: SmtpClient always tries to authenticate
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+Trying to use System.Net.Mail.SmtpClient to send mail and it is failing
+because System.Net.Mail.SmtpClient.Credentials is not null, even though I'm
+not setting it.  Mail server is Postfix 2.2.10
+Steps to reproduce the problem:
+using System;
+using System.Net.Mail;
+namespace email_test
+        class MainClass
+        {
+                public static void Main(string[] args)
+                {
+                        MailMessage message = new
+MailMessage("bryan at bryanbrownreptiles.com", "bryan at bryanbrownreptiles.com",
+"test mail", "this is a test");
+                        SmtpClient client = new SmtpClient("localhost");
+                        //Uncomment the following line and it will work
+                        //client.Credentials = null;
+                        client.Send(message);
+                        Console.WriteLine("the message was sent");
+                }
+        }
+Actual Results:
+Unhandled Exception: System.Net.Mail.SmtpException: 503 Error:
+authentication not enabled
+  at System.Net.Mail.SmtpClient.Authenticate (System.String Username,
+System.String Password) [0x00000]
+  at System.Net.Mail.SmtpClient.PerformAuthentication () [0x00000]
+  at System.Net.Mail.SmtpClient.Send (System.Net.Mail.MailMessage message)
+  at email_test.MainClass.Main (System.String[] args) [0x00000]
+Expected Results:
+Should just send mail without trying to send Authentication, for some
+reason the Credentials check at line 660 (1.2.4) does not equal null.
+How often does this happen? Always
+Additional Information: Smtp Server is Postfix 2.2.10
