Is there a way to alter the subject line of an encrypted message? We would like to provide the receiver of the email with some kind of feedback that the message was encrypted.

Currently not. I'll put it on the todo list. What most users do is use a subject trigger that triggers encryption. You want to encrypt all messages and add for example "[message was encrypted]" when the message is encrypted? kind regards, Martijn > **···** > > > Andreas Behr > > Diplom Informatiker (FH) > > > > Krämer IT Solutions GmbH > > Alte Koßmannschule > > Koßmannstraße 7 > > 66571 Eppelborn > > > > ---- Gesetzliche Pflichtangaben > > Krämer IT Solutions GmbH > > Koßmannstraße 7 > > 66571 Eppelborn > >                                                                             > > Registergericht: Amtsgericht Saarbrücken, HRB 14379 > > Geschäftsführer: Michael Krämer > > > > \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ > > Users mailing list > > Users(a)lists.djigzo.com > > [http://lists.djigzo.com/lists/listinfo/users](http://lists.djigzo.com/lists/listinfo/users) > > -- > Djigzo open source email encryption ---

As far as i understand he want's to get a subject on \*inbound\* mail to see if the mail arrived encrypted and was decrypted by Djigzo.... This may be useful for the end-user because the x-djigzo-header-\* will not be visible to the end-user. But i wonder if this get bad habit in the long run to teach the user to rely on some subject extension... Regards Andreas ---

Hi all, > As far as i understand he want's to get a subject on \*inbound\* mail to .. yes. Inbound mail decrypted by Djigzo does not show any visible sign of that fact. I know it is a bad idea to teach the user to rely on something in the subject line, but I not sure how else to indicate the encrypted transport.

Djigzo adds some custom headers in the form X-Djigzo-\* to the message when a message was encrypted and/or signed. Because Djigzo removes all X-Djigzo-\* headers when the message is received (for an internal user) senders cannot 'spoof' these X-Djigzo-\* headers. Using the X-Djigzo-\* is the most reliable way (apart from decrypting and checking the S/MIME message in your local mail client) but not really user friendly 🙂 It is of course possible to add something like [decrypt] to the subject after decrypting but to prevent it from being 'spoofed' all incoming mail must be checked and any [decrypt] part must be removed. If a user replies to a message the subject will contain [decrypt] so for outgoing email it must be removed as well because the subject did initially not contain the line. I'll put it on the todo list Kind regards, Martijn Andreas Behr - Krämer IT Solutions wrote: > **···** > > > Hi all, > > > > > As far as i understand he want's to get a subject on \*inbound\* mail to .. > > > > yes.
