Download/Retrieve Email from Yahoo account in C++/CLI/CLR

In previous section, I introduced how to download emails from Gmail account. In this section, I will introduce how to download emails from your Yahoo account in C++/CLI/CLR.

Introduction

Yahoo POP3 server address is pop.mail.yahoo.com. It requires SSL connection on 995 port; Yahoo IMAP4 server address is imap.mail.yahoo.com . It requires SSL connection on 993 port. You should use your Yahoo email address as the user name for user authentication. For example: your email is myid@yahoo.com, and then the user name should be myid@yahoo.com.

Server Port SSL Protocol
pop.mail.yahoo.com 995 SSL required Pop3
imap.mail.yahoo.com 993 SSL required Imap4

Important

If you got authentication error, you need to enable Allowing less secure apps in your Yahoo account. Although Yahoo supports OAUTH, but it doesn’t provide mail permission, so OAUTH is not a solution for Yahoo mail.

Note

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

[C++/CLI/CLR Example - Retrieve emails from Yahoo account using IMAP4]

The following example codes demonstrate how to download emails from Yahoo account using IMAP4 protocol.

    // If the folder is not existed, create it.
    if (!Directory::Exists(mailbox))
    {
        Directory::CreateDirectory(mailbox);

    try

        array<MailInfo^> ^infos = oClient->GetMailInfos();
        for (int i = 0; i < infos->Length; i++)
