Hello Krzemciak,
I see no one has answered this question yet, so I recommend contacting Support at 1-800-821-2797.
Does XDM software permit restricting the maxiumum size of scanned document to logged-in user's e-mail, saving it in encrypted format on System server and sending it to user who initiates e-mail scanning process from encrypted link HTTPS to scanned document? The message should contain informations about time after which the System will automatically clear scanned document from server. Scanned document download will be available only for user who realizes scanning process on device.
Best regards,
Klaus Simmons
