Sending Mail Attachments in Delphi

I know this is a big question.

I would like to know how to send a mail message with a MAPI encoded attachment in Delphi.
Please do not direct me to third party controls that are not free and available on the internet.
I need to send it in Microsoft Exchange format.

I know the scope of the question which is why I have put so many points out.

I few pointers might be all I need to do this.
The attached document will be in Word95 format, not that it should be significant.

my email address is should you wish to mail me.

The following code sends a message and attachment from Fred to John.  (Add mapi to the uses clause.)

  Originator, Recipient: TMapiRecipDesc;
  FileAttachment: TMapiFileDesc;
  MapiMsg: TMapiMessage;
  if (MapiLogOn(0, nil, nil, MAPI_LOGON_UI or MAPI_NEW_SESSION , 0, @hMapi) = SUCCESS_SUCCESS) then
      FillChar(MapiMsg, SizeOf(TMapiMessage), 0);

      MapiMsg.lpszSubject := 'Test Message';
      MapiMsg.lpszNoteText := ' Hello.  This is the message text.  The End.';
      MapiMsg.flFlags := MAPI_RECEIPT_REQUESTED;

      FillChar(Originator, SizeOf(TMapiRecipDesc), 0);
      Originator.lpszName := 'Fred';
      Originator.lpszAddress := '';
      Originator.ulRecipClass := MAPI_ORIG;
      MapiMsg.lpOriginator := @Originator;

      MapiMsg.nRecipCount := 1;
      FillChar(Recipient, SizeOf(TMapiRecipDesc), 0);
      Recipient.lpszName := 'John';
      Recipient.lpszAddress := '';
      Recipient.ulRecipClass := MAPI_TO;
      MapiMsg.lpRecips := @Recipient;

      MapiMsg.nFileCount := 1;
      FillChar(FileAttachment, SizeOf(TMapiFileDesc), 0);
      FileAttachment.flFlags := 0;
      FileAttachment.lpszPathName := 'C:\autoexec.bat';
      FileAttachment.lpszFileName := 'autoexec.bat';
      MapiMsg.lpFiles := @FileAttachment;

      MapiSendMail(hMapi, 0, MapiMsg, MAPI_LOGON_UI, 0);

      MapiLogOff(hMapi, 0, 0, 0);

This is freeware, easy, everything is possible, lot's of documenation, with source, for ALL delphi versions, for EVERY platform and good. But JimBob's answer is also correct.

Look at :

It's really recommended just to have a look at it.

Have fun,
