Increase the number of file types that automatically get protected when attached to a protected email, beyond Office and PDF.
Currently, when you attach an unprotected Office document or PDF to an email, and then protect the email, the attachment inherits the protection. This should be expanded to include other file types.
PDF is now covered in addition to Office files, so we have edited the definition of this request to focus on additional file types. If you primarily cared about PDF you can remove your vote from this one.
