TNMSMTP component - "530 authentication required"

Good day to All.
I'm new here and hope someone can help me.
I'm using Delphi 5's TNMSMTP component to send E-Mail from my application. I don't receive Email here.
On some Host's, (Like smtp.saix.net) in South Africa all is working good.
Some other hosts (Like smtp.bizmail.yahoo.com), needs Authentication, and I cannot get a way to enable it in the TNMSMTP component.
I get the Error message '530 authentication required'.
Can some please help me on this OR show me some other way to send Email using a host that require authentication?

My code look as follow and work good on some providers.
   NMSMTP1.Host := Host;       //'smtp.saix.net';
   NMSMTP1.UserID := UserId;    //'user@Provider.co.za';
   NMSMTP1.PostMessage.FromAddress := FromAdress; //'mstander@inteletrack.co.za';
   NMSMTP1.PostMessage.ToAddress.Text := Email1; //'mstander@inteletrack.co.za';
   NMSMTP1.SubType := mtHTML; // or mtPlain'
   NMSMTP1.PostMessage.Body.Text := Edit1.text;
   NMSMTP1.PostMessage.Subject := 'TEST EMAIL send on '+DateTimeToStr(Now);
   NMSMTP1.PostMessage.Body.Add(' Please do not reply to this address. ');

TNMSMTP don't support authentication, you can use Indy )http://www.indyproject.org/Sockets/wizard/DownloadWizard.EN.aspx) it's have IdSMTP1.AuthType:=atDefault

Thanks, With a bit of strugle I had Download Indy 9, and install in in my Delphi 5.
The only problem is that Indi 9 does not have the AuthType atDefault parameter.
I had  download indi 10, but still strigle to install it as the automatic install on Indi's website 'http://www.indyproject.org/Sockets/Download/Files/Indy10.EN.aspx does noet work.
Will let you know if Indi 10 had an AuthType atDefault option.

Thanks, I believe It is the Sullution, I just cannot get it right to add the INDI 10 components into Delhi 5. I try to compile the things ect, but there is always some problem. The big problem is the Auto installer is not available to down. I had once get it right to install only some of the Core? components.
