I got it working with one PDF attached from oracle using SMTP, but do not no how to get the second attachment onto the same email working.  
I tried duplicating the code, repeating it from the begin_attachment to the end_attachment call only changing filenm parameter value but no luck.

It appears that the dbms_lob.read on the second file does not return any data.
demo_mail.begin_attachment(conn => conn,mime_type => v_mime_type_bin,inline => TRUE,
                                   filename => filenm, transfer_enc => 'base64');
   BEGIN
      fil := BFILENAME(dirname, filenm);
      file_len := dbms_lob.getlength(fil);
      dbms_output.put_line('file_len is '||file_len);
      modulo := mod(file_len, amt);
      pieces := trunc(file_len / amt);
      if (modulo <> 0) then
         pieces := pieces + 1;
      end if;
      dbms_lob.fileopen(fil, dbms_lob.file_readonly);
      dbms_lob.read(fil, amt, filepos, buf);
      data := NULL;
      FOR i IN 1..pieces LOOP
         filepos := i * amt + 1;
         file_len := file_len - amt;
         data := utl_raw.concat(data, buf);
         chunks := trunc(utl_raw.length(data) / MAX_LINE_WIDTH);
         IF (i <> pieces) THEN
            chunks := chunks - 1;
         END IF;
          demo_mail.write_raw( conn => conn,
                                message => utl_encode.base64_encode(data ) );
            data := NULL;
         if (file_len < amt and file_len > 0) then
            amt := file_len;
         end if;
         dbms_lob.read(fil, amt, filepos, buf);
      END LOOP;
      dbms_lob.fileclose(fil);
   END;
    
   demo_mail.end_attachment(conn => conn );
END begin_attachment;

Your "demo_mail"  end_attachment  code needs to differentiate the mime delimiter for end one mime block and the end of the last mime block

I'm assuming you have some sort of "begin mime block" procedure too probably something called "begin_attachment" or something like that.

you also need to specify in your email header 'multipart/mixed; boundary="--some_unique_string'

Sorry,
I have attcahed the complete code, as I do not understand how the mime delimiter works and how I should build a differentiation  into the mime block(begin / end attchment blocks?). The demo_mail code that I found and use does not seem to make provison for that in the end_attachment part.
The  'multipart/mixed; boundary=" is specified.

can you post the code for demo_mail.begin_attachment  and demo_mail.end_attachment?


the general layout of mime blocks should be...

write mime boundary... || crlf
write mime content type || crlf
write  disposition inline/attachment/filename ||crlf
write data || crlf
write crlf
if last mime block then write mime boundary

probably what is happening is your end_attachment assumes only one attachement ever so it writes the end boundary always.
