Then your MUA probably set "application/pdf" as Content-Type, not "application/pdfa".

See https://en.wikipedia.org/wiki/MIME#Multipart_messages and have a look at your email source.

  Content-Type: application/pdf
  Content-Transfer-Encoding: base64
  Content-Disposition: attachment;
	filename=invoice-123.pdf
