I'm half way to answering my own question (as no one else has!). I'm
beginning to think this is a VS2005 problem, as I just built a test simple
DLL in VS2003 modelled on the code I quoted below, which uses the following
exported function, WHICH WORKS!

// -----------------------------------------------------
extern "C" _declspec(dllexport) BOOL SendSMTPMessage(LPCTSTR szServer,
LPCTSTR szFrom, LPCTSTR szTo, LPCTSTR szSubject,

            LPCTSTR szAttachments, LPCTSTR szBody)
{

CoInitialize(NULL);
{
  CMimeMessage msg;
  msg.SetSender(szFrom);
  //msg.SetSenderName(_T("Peter Boulton"));
  msg.AddRecipient(szTo);
  msg.SetSubject(szSubject);
  msg.AddText(szBody);
  if(szAttachments != NULL)
   msg.AttachFile(szAttachments);
  msg.SetPriority(ATL_MIME_HIGH_PRIORITY);

  // Attempt to connect to the specified SMTP server
  CSMTPConnection connection;
  if (!connection.Connect(szServer))
  {
   MessageBox(NULL, _T("Unable to connect to server!"), "SMTP.DLL", MB_OK);
   return FALSE;
  }
  else
  {
   if (!connection.SendMessage(msg))
   {
    MessageBox(NULL, _T("Connected to server but failed to send message!"),
"SMTP.DLL", MB_OK);
    return FALSE;
   }
  }
}
CoUninitialize();

MessageBox(NULL, "Your email was sent!", "SMTP.DLL", MB_OK);

return TRUE;
}
// -----------------------------------------------------

Over the weekend I shall try to port the DLL to VS2005 and see if it works!

Incidentally, the original (VS2005) code falls over during one of the
WriteData() calls within CSMTPConnection::SendMessage().

Any feedback welcome, in the meantime! Thanks!

Hi,

I'm trying to send an email using the following code, but it always fails
to send the message on the "if (!connection.SendMessage"(msg))" line:
#include <atlsmtpconnection.h> // Required for smtp mail!

void SendIt(void)
{
CoInitialize(NULL);
{
CMimeMessage msg;
msg.SetSender(m_From);
msg.SetSenderName(_T("Peter Boulton"));
msg.AddRecipient(m_To);
msg.SetSubject(m_Subject);
msg.AddText(m_Body);
msg.AttachFile(m_Attachment);
msg.SetPriority(ATL_MIME_HIGH_PRIORITY);

// Attempt to connect to the specified SMTP server
CSMTPConnection connection;
if (!connection.Connect(m_Server))
  MessageBox(_T("Unable to connect to server!"));
else
{
  if (!connection.SendMessage(msg)) // <<<<< Always fails here!
   MessageBox(_T("Connected to server but failed to send message!"));
}
}
CoUninitialize();
}

All the variables are correctly initialised and set etc..

Any help greatly appreciated! This is in an MFC dialog application, built
and compiled with VS2005.
