Send Email using Yahoo in Visual C++

In previous section, I introduced how to send email using Gmail account. In this section, I will introduce how to use your Yahoo account to send email in Visual C++.

Introduction

Yahoo SMTP server address is smtp.mail.yahoo.com. It supports both Normal/Implicit SSL/Explicit SSL (TLS) connection to do user authentication, and you should use your Yahoo email address as the user name for ESMTP authentication. For example: your email is myid@yahoo.com, and then the user name should be myid@yahoo.com.

If you want to use SSL connection with Yahoo SMTP server, you must set the port to 465.

Server Port SSL/TLS
smtp.mail.yahoo.com 25, 587 TLS
smtp.mail.yahoo.com 465 SSL

Note

Remarks: All of samples in this section are based on first section: A simple Visual C++ project. To compile and run the following example codes successfully, please click here to learn how to create the test project and add reference of EASendMail to your project.

Important

If you got authentication error, you need to enable Allowing less secure apps in your Yahoo account. Or you can generate App Passwords and use this app password instead of your user password.

Although Yahoo supports OAUTH, but it doesn’t provide mail permission, so OAUTH is not a solution for Yahoo mail.

[Visual C++ Example - Send email using Yahoo account over direct SSL connection]

The following example codes demonstrate how to send email using Yahoo account.

Note

To get the full sample projects, please refer to Samples section.

#include "stdafx.h"
#include <tchar.h>
#include <Windows.h>

#include "EASendMailObj.tlh"
using namespace EASendMailObjLib;

const int ConnectNormal = 0;
const int ConnectSSLAuto = 1;
const int ConnectSTARTTLS = 2;
const int ConnectDirectSSL = 3;
const int ConnectTryTLS = 4;

int _tmain(int argc, _TCHAR* argv[])
{
    ::CoInitialize(NULL);

    IMailPtr oSmtp = NULL;
    oSmtp.CreateInstance(__uuidof(EASendMailObjLib::Mail));
    oSmtp->LicenseCode = _T("TryIt");

    // Set your Yahoo email address
    oSmtp->FromAddr = _T("myid@yahoo.com");
    // Add recipient email address
    oSmtp->AddRecipientEx(_T("support@emailarchitect.net"), 0);

    // Set email subject
    oSmtp->Subject = _T("simple email from Visual C++ with Yahoo account");
    // Set email body
    oSmtp->BodyText = _T("this is a test email sent from Visual C++ project with Yahoo");

    // Yahoo SMTP server address
    oSmtp->ServerAddr = _T("smtp.mail.yahoo.com");

    // For example: your email is "myid@yahoo.com", then the user should be "myid@yahoo.com"
    oSmtp->UserName = _T("myid@yahoo.com");
    oSmtp->Password = _T("yourpassword");

    // Because yahoo deploys SMTP server on 465 port with direct SSL connection.
    // So we should change the port to 465.
    oSmtp->ServerPort = 465;

    // detect SSL/TLS automatically
    oSmtp->ConnectType = ConnectSSLAuto;

    _tprintf(_T("Start to send email via Yahoo account ...\r\n"));

    if(oSmtp->SendMail() == 0)
    {
        _tprintf(_T("email was sent successfully!\r\n"));
    }
    else
    {
        _tprintf(_T("failed to send email with the following error: %s\r\n"),
            (const TCHAR*)oSmtp->GetLastErrDescription());
    }

    return 0;
}

[Visual C++ Example - Send email using Yahoo account over TLS connection on 587 port]

The following example codes demonstrate how to send email using Yahoo account over TLS on 587 port.

#include <Windows.h>

#include "EASendMailObj.tlh"
using namespace EASendMailObjLib;

const int ConnectNormal = 0;
const int ConnectSSLAuto = 1;

    oSmtp->Subject = _T("simple email from Visual C++ with Yahoo account");
    // Set email body
    oSmtp->BodyText = _T("this is a test email sent from Visual C++ project with Yahoo");

    // Yahoo SMTP server address
    oSmtp->ServerAddr = _T("smtp.mail.yahoo.com");

    // For example: your email is "myid@yahoo.com", then the user should be "myid@yahoo.com"
    oSmtp->UserName = _T("myid@yahoo.com");
    oSmtp->Password = _T("yourpassword");

    // set 587 port
    oSmtp->ServerPort = 587;

    // detect SSL/TLS automatically
    oSmtp->ConnectType = ConnectSSLAuto;

    _tprintf(_T("Start to send email via Yahoo account ...\r\n"));

    if(oSmtp->SendMail() == 0)
    {
        _tprintf(_T("email was sent successfully!\r\n"));
    }
    else
    {
        _tprintf(_T("failed to send email with the following error: %s\r\n"),
            (const TCHAR*)oSmtp->GetLastErrDescription());
    }

    return 0;
}

TLS 1.2

TLS is the successor of SSL, more and more SMTP servers require TLS 1.2 encryption now.

If your operating system is Windows XP/Vista/Windows 7/Windows 2003/2008/2008 R2/2012/2012 R2, and you got connection error with SSL/TLS connection, you need to enable TLS 1.2 protocol in your operating system like this:

Enable TLS 1.2 on Windows XP/Vista/7/10/Windows 2008/2008 R2/2012
