The following Managed C++/CLI 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 SmtpMail.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.
Before you can use the following codes, please download EASendMail SMTP Component and install it on your machine at first. Full sample proejcts are included in this installer.

int main(array<System::String ^> ^args)
{
SmtpMail ^oMail = gcnew SmtpMail("TryIt");
SmtpClient ^oSmtp = gcnew SmtpClient();
// Set sender email address, please change it to yours
oMail->From = "test@emailarchitect.net";
// Set recipient email address, please change it to yours

try
{
// Load EML file to a binary data
FileStream ^fs = gcnew FileStream("c:\\my folder\\test.eml",
FileMode::Open, FileAccess::Read, FileShare::Read);
array<Byte> ^data = gcnew array<Byte>(fs->Length);
fs->Read(data, 0, fs->Length);
fs->Close();
// Forward Eml file with 100% original data
Console::WriteLine("start to send email from Managed C++...");
oSmtp->SendRawMail(oServer, data, oMail->From, oMail->To);
