Attachements in SPX
Attachements of encrypted mails will be attached in the PDF file.
It would be more user friendly, if all attachements could be seperatly attached to the eMail. Not all receipients have acrobat reader installed, but use for default Edge or similar to view PDF files.

A better idea is to do it the Sophos Safeguard Synchronized Encryption way, use HTML5 instead of PDF. Normal users especially non-business users Don't have PDF readers installed anymore, the internet browsers are capable of viewing the usual PDF files just fine.
Much more users can do this with native internet browsers: https://community.sophos.com/kb/en-us/124440 than that users have Adobe Reader installed these days.
