Trying to send an email using sendEmail and Gmail with attached PDF with embedded exe file but gmail fails with "illegal attachment on your message". This used to work, has google now blocked these things as I can't get Social Engineerig Tooolkit to send either.

The PDF file is one I have created and this sends OK.

The exe file is windows notepad.exe which is Not detected by AV's.
This fails using the same Gmail set-up as when sending the pdf only.

Using msf exploit/windows/fileformat/adobe_pdf_embedded_exe to add the exe to the PDF.

Any pointers please
