Visual C++ - Send EML File

The following c++ example codes demonstrate how to load EML file and forward it to specified recipient.

EML file is e-mail message saved by Microsoft Outlook Express or other e-mail programs; may also contain an e-mail attachment, or file sent with the message.

If you want to load EML file and edit it, you can use LoadMessage method to load EML file and edit it.

If you do not want to edit the EML file, and you just need to simply forward the EML file to other recipient with 100% original data, then please see the following example codes.

using namespace EASendMailObjLib;

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

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

    // Set your sender email address
    oSmtp->FromAddr = _T("test@emailarchitect.net");

    // Add recipient email address
    oSmtp->AddRecipientEx( _T("support@emailarchitect.net"), 0 );

    // Your SMTP server address
    oSmtp->ServerAddr = _T("smtp.emailarchitect.net");

    // User and password for ESMTP authentication, if your server doesn't
    // require User authentication, please remove the following codes.
    oSmtp->UserName = _T("test@emailarchitect.net");
    oSmtp->Password = _T("testpassword");

    // If your SMTP server requires SSL connection, please add this line
    // oSmtp->SSL_init();

    // Load EML file to body text temporally
    oSmtp->ImportMail( _T("c:\\temp\\my.eml"));

    // Assign Eml file data to raw content
    oSmtp->put_raw_Content( oSmtp->BodyText );
    _tprintf(_T("Start to send email ...\r\n" ));

    // Forward EML file with 100% original data
    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());
    }

    if( oSmtp != NULL )
        oSmtp.Release();

    return 0;
