sending event email

[ccMcBride]

using delphi 10 seattle,
my email is setup like so:

Code:

      dmEmail.emMessage.ContentType := 'text/calendar;method=REQUEST';
      with tIDText.Create(dmEMail.emMessage.Messageparts) do
      begin
         ContentType := 'text/calendar;method=REQUEST';
//         parentPart := 0;
         Body.Text := eventText.Text;
      end;
      with TIdAttachmentFile.Create(dmEmail.emMessage.MessageParts, fName) do
      begin
         ContentDisposition := 'attachment';
         ContentType := 'text/calendar;method=REQUEST';
         ExtraHeaders.Values['Content-ID'] := ExtractFileName(fName);
         ContentID := ExtractFileName(fName);
         Filename := ExtractFilename(fName);
//           parentPart := 1;
      end

where fName is a .ics file that I am attempting to send.
currently, the contents of the ics file is:

Code:

BEGIN:VCALENDAR
VERSION:2.0
METHOD:REQUEST
BEGIN:VEVENT
ORGANIZER;CN=Connie M.:MAILTO:[real code has a valid email address here]
DTSTART:20190827T220000Z

BEGIN:VALARM

END:VALARM
END:VEVENT
END:VCALENDAR

my mail.txt (saving the message to file) is this:

Code:

Subject: Event on 27th

.

what I am getting in return :

 raised exception class EIdSMTPReplyError with message 'STOREDRV.submission.excetption : invalid recipentsException;
failed to process message due to a permanent exception with mesage.  Amessage can't be sent because it contains no recipients.  InvalidRecipientsException a message can't be sent because it contains no recipients. 


since I DO have a recipient, I'm not sure why I am getting this message.

what I am trying to do :
send an email with an event invite, with the 'accept/decline' stuff in the email.

so far, the most I have accomplished is only getting the ics file as an attachment.

it is VERY possible the ics file is incorrect (this is my first time attempting this)
any ideas what I am missing?
