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(NTLM).

Usage Example:

[Visual Basic]
    
Private Sub SendEmail()
  Dim oSmtp As EASendMailObjLib.Mail
  Set oSmtp = New EASendMailObjLib.Mail

  'The license code for EASendMail ActiveX Object, 
  'for evaluation usage, please use "TryIt" as the license code.
  oSmtp.LicenseCode = "TryIt"

  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


[Visual C++]
#include "stdafx.h"
#include <comdef.h>
#include <iostream>

#include "easendmailobj.tlh"
using namespace EASendMailObjLib;
using namespace std;

void SendEmail()
{
  ::CoInitialize( NULL );
  IMailPtr oSmtp = NULL;
  oSmtp.CreateInstance("EASendMailObj.Mail");
  //The license code for EASendMail ActiveX Object, 
  //for evaluation usage, please use "TryIt" as the license code.
  oSmtp->LicenseCode = _bstr_t("TryIt");
	
  oSmtp->ServerAddr = _bstr_t( "mail.adminsystem.net" );
  oSmtp->FromAddr = _bstr_t( "test@adminsystem.net" );
  oSmtp->AddRecipient( _bstr_t("Support Team"), 
                          _bstr_t("support@adminsystem.net"), 0 );

  oSmtp->>AuthType = 3;
  oSmtp->UserName = _bstr_t("test@adminsystem.net");
  oSmtp->Password = _bstr_t("test");
  
  oSmtp->BodyText = _bstr_t("Hello, this is a test....");
  if( oSmtp->SendMail() == 0 )
    cout << "Message delivered!" << endl;
  else
    cout << (const char*)(oSmtp->GetLastErrDescription()) << endl;
}
