AuthType Property

This property specifies the type of ESMTP authenction.

Value	Meaning
-1	Automatically
0 (Default)	AUTH LOGIN
1	AUTH NTLM(Secure Password Authentication)
2	AUTH CRAM-MD5
3	AUTH PLAIN
4	AUTH MSN

If you didn't specify UserName and Password properties, AuthType property is meaningless.

So far only Microsoft Exchange Server supports Secure Password Authentication.

Usage Example:

Private Sub SendEmail()
  Dim oSmtp As AOSMTPLib.Mail
  Set oSmtp = New AOSMTPLib.Mail

  oSmtp.ServerAddr = "mail.adminsystem.net"
  oSmtp.FromAddr = "test@adminsystem.net"
  oSmtp.AddRecipient "Support Team", "support@adminsystem.net", 0

  oSmtp.AuthType = 1
  oSmtp.UserName = "test@adminsystem.net"
  oSmtp.Password = "test"
  
  oSmtp.BodyText = "Hello, this is a test...."
  If oSmtp.SendMail() = 0 Then
    MsgBox "Message delivered!"
  Else
    MsgBox oSmtp.GetLastErrDescription()
  End If
End Sub

private void SendEmail()
{
  AOSMTPLib.MailClass oSmtp = new AOSMTPLib.MailClass();
  oSmtp.ServerAddr = "mail.adminsystem.net";
  oSmtp.FromAddr = "test@adminsystem.net";
  oSmtp.AddRecipient( "Support Team", "support@adminsystem.net", 0 );

  oSmtp.AuthType = 0;
  oSmtp.UserName = "test@adminsystem.net";
  oSmtp.Password = "test";
  
  oSmtp.BodyText = "Hello, this is a test....";
  if( oSmtp.SendMail() == 0 )
    Console.WriteLine( "Message delivered!" );
  else
    Console.WriteLine( oSmtp.GetLastErrDescription());
}
