Send Email using Yahoo in Managed C++/CLI

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 Managed 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 Managed C++/CLI 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.

[Managed C++/CLI 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"

using namespace System;
using namespace EASendMail;

int main(array<System::String ^> ^args)
{
    try
    {
        SmtpMail ^oMail = gcnew SmtpMail("TryIt");
        // Your Yahoo email address
        oMail->From = "myid@yahoo.com";
        // Set recipient email address, please change it to yours
        oMail->To = gcnew AddressCollection("support@emailarchitect.net");

        // Set email subject
        oMail->Subject = "test email from Managed C++ with Yahoo account";
        // Set email body
        oMail->TextBody = "this is a test email sent from Managed C++ project with yahoo";

        // Yahoo SMTP server address
        SmtpServer ^oServer = gcnew SmtpServer("smtp.mail.yahoo.com");

        // For example: your email is "myid@yahoo.com", then the user should be "myid@yahoo.com"
        oServer->User = "myid@yahoo.com";
        oServer->Password = "yourpassword";

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

        // detect SSL/TLS automatically
        oServer->ConnectType = SmtpConnectType::ConnectSSLAuto;

        Console::WriteLine("start to send email with SSL connection...");

        SmtpClient ^oSmtp = gcnew SmtpClient();
        oSmtp->SendMail(oServer, oMail);

        Console::WriteLine("email was sent successfully!");
    }
    catch (Exception ^ep)
    {
        Console::WriteLine("failed to send email with the following error:");
        Console::WriteLine(ep->Message);
    }

    return 0;
}

[Managed C++/CLI 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.

Note

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

#include "stdafx.h"
using namespace System;
using namespace EASendMail;
int main(array<System::String ^> ^args)
{
    try
    {
        SmtpMail ^oMail = gcnew SmtpMail("TryIt");
        // Your Yahoo email address
        oMail->From = "myid@yahoo.com";
        // Set recipient email address, please change it to yours
        oMail->To = gcnew AddressCollection("support@emailarchitect.net");

        // Set email subject
        oMail->Subject = "test email from Managed C++ with Yahoo account";
        // Set email body
        oMail->TextBody = "this is a test email sent from Managed C++ project with yahoo";

        // Yahoo SMTP server address
        SmtpServer ^oServer = gcnew SmtpServer("smtp.mail.yahoo.com");

        // For example: your email is "myid@yahoo.com", then the user should be "myid@yahoo.com"
        oServer->User = "myid@yahoo.com";
        oServer->Password = "yourpassword";

        // set 587 port
        oServer->Port = 587;

        // detect SSL/TLS automatically
        oServer->ConnectType = SmtpConnectType::ConnectSSLAuto;

        Console::WriteLine("start to send email with SSL connection...");

        SmtpClient ^oSmtp = gcnew SmtpClient();
        oSmtp->SendMail(oServer, oMail);

        Console::WriteLine("email was sent successfully!");
    }
    catch (Exception ^ep)
    {
        Console::WriteLine("failed to send email with the following error:");
        Console::WriteLine(ep->Message);
    }

    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
