[Evolution] Feature request: read only

[Ben FrantzDale <bfrantzdale hmc edu>]

I use Evolution as follows:
I keep everything in the inbox, even old things (I'm lazy. I
occasionally back up older personal data.)
I have a VFloder for all my mailing lists and for mail to me, etc.

With that usage it would be great if there were a field like the ``!''
field on a message that could make a message read only. That way I could
``save'' what I wanted without moving things around and I could then not
wory about deleting the wrong things.
