C++/CLI Example

Gmail IMAP4 server address is "imap.gmail.com". It requires SSL connection on 993 port, and you should use your Gmail email address as the user name for user authentication. For example: your email is "gmailid@gmail.com", and then the user name should be "gmailid@gmail.com".

To retrieve email from Gmail account, you need to enable POP3 or IMAP4 access in your gmail account settings.

Because Gmail POP3 server doesn't work like normal POP3 server, it hides old emails automatically even the email was not deleted, so we suggest that you use IMAP4 protocol.

// The following example codes demonstrate retrieving email from Gmail IMAP4 server
// To get full sample projects, please download and install EAGetMail on your machine.
// To run it correctly, please change email server, user, password, folder, file name value to yours

Code:

#include "stdafx.h" 

using namespace System; 
using namespace System::IO; 

// Add EAGetMail namespace
using namespace EAGetMail; 

int main(array<System::String ^> ^args) 
{ 
    // Create a folder named "inbox" under current directory
    // to save the email retrieved.
    String ^curpath = Directory::GetCurrentDirectory(); 
    String ^mailbox = String::Format("{0}\\inbox", curpath); 

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

    // Gmail IMAP server is "imap.gmail.com"
    MailServer ^oServer = gcnew MailServer("imap.gmail.com", 
        "gmailid@gmail.com", "yourpassword", ServerProtocol::Imap4 ); 
    MailClient ^oClient = gcnew MailClient("TryIt"); 

    // Enable SSL connection
    oServer->SSLConnection = true; 

    // Set 993 IMAP4 SSL port
    oServer->Port = 993; 

    try 
    { 
        oClient->Connect(oServer); 
        array<MailInfo^> ^infos = oClient->GetMailInfos(); 
        for (int i = 0; i < infos->Length; i++) 
        { 
            MailInfo ^info = infos[i]; 
            Console::WriteLine("Index: {0}; Size: {1}; UIDL: {2}", 
                info->Index, info->Size, info->UIDL); 

            // Receive email from Gmail IMAP server
            Mail ^oMail = oClient->GetMail(info); 

            Console::WriteLine("From: {0}", oMail->From->ToString()); 
            Console::WriteLine("Subject: {0}\r\n", oMail->Subject); 

            // Generate an email file name based on date time.
            System::DateTime d = System::DateTime::Now; 
            System::Globalization::CultureInfo ^cur = gcnew 
                System::Globalization::CultureInfo("en-US"); 
            String ^sdate = d.ToString("yyyyMMddHHmmss", cur); 
            String ^fileName = String::Format("{0}\\{1}{2}{3}.eml", 
                mailbox, sdate, d.Millisecond.ToString("d3"), i); 

            // Save email to local disk
            oMail->SaveAs(fileName, true); 

            // Mark email as deleted from Gmail IMAP4 server.
            oClient->Delete(info); 
        } 

        // Quit and pure emails marked as deleted from Gmail IMAP4 server.
        oClient->Quit(); 
    } 
    catch (Exception ^ep) 
    { 
        Console::WriteLine(ep->Message); 
    } 

    return 0; 
}
