well let's say that from time to time I want to send confidential information to you.  
And since you only have an Email-Client like Outlook or Thunderbird and you do not want to use some encryption software, it is my responsibility to encrypt the information.

Therefore I want Djigzo to send this confidential information as an encrypted PDF, when I add "-ENC-" to the subject line of an email to you.

Any other other email should be send as it is.

Kind regards,

Stefan

The easiest and most secure way to setup PDF encryption is to use the  
"one time password" (OTP) mode with the build in portal. If you want I  
can send you an example PDF encrypted message.

Kind regards,

Martijn Brinkers
