Ok I'll look into it. Can't promise anything but I'll do my best :) >>> - User viewable tagging (subject extension) for incoming >>> signed/encrypted mail >>> ( Sometimes it is really useful if the user is able to check) >> If I understand you, you want to add some sort of banner to the message >> containing the security information? something similar to what's added >> to the headers but now visible for the end-user? > > Yes , this should be a easy work around to see if the message was > signed/encrypted before it reached the gateway. No Outlook user willl > every read e-mail headers :-( What might be problematic is that a banner can be easily spoofed. Any djigzo-* header is removed when the email enters Djigzo. Therefore the security headers cannot be spoofed. With a security banner (a text or HTML text part) it's nearly impossible to detect whether the banner is spoofed. So, the banner should only be viewed as informational. > No problem, i will try to get involved at Thunderbird etc. to see if > there is some work in progress on the crypto part.

Perhaps TrustedBird (a security enhanced Thunderbird) already supports this? http://www.trustedbird.org Kind regards, Martijn -- Djigzo open source email encryption _______________________________________________ Users mailing list [email protected] http://lists.djigzo.com/lists/listinfo/users
