I'm pleased that Zimbra provides users with a way to view the full headers of a received (or, amusingly, even a sent) message.
Alas, there seems no easy way to *forward* such a message to someone with those full headers attached, as I do in Mutt every day.
I would like to submit (and hear comment on) 2 feature requests:
1) Add a dropdown menu to Forward (similar to the one on Reply to its left) where the non-default option is "Forward w/headers".
2) Add a configurable button to the button command bar labeled "Report This Email", which automagically sets up a full-header forward to the system's email administrator for further investigation, preferably tagged in such a fashion that it can be filtered into a folder. Who this goes to, and whether it waits for the user to comment, could best be tunable by COS and domain.
Right now, I'll have to have users pop the header dialog, copy and paste into a message to me, and that just won't happen. :-)
