CentOS - Dec 2016 - Semi-OT: thunderbird displaying inline

Hi, folks,

    This is odd. Just recently, at home, even though I have it set to display 
messages as plain text, I'm suddenly seeing pics attached to spam inline, as
though I had it set to display html.

    Can't find anything to make it stop - anyone have a clue?

You are probably being confronted with content with content-disposition:
inline. Many muas display such content, exposing you to possible attacks
that target bugs in rendering libraries.

Not sure if there's a switch to disable the rendering of content with
disposition inline in TB but at least now you know what to search
for :) . Evolution does not have such an switch on C6 and C7, but recent
releases do: https://bugzilla.gnome.org/show_bug.cgi?id=769388

Regards,
Leonard.

Thanks. Knowing the "magic words" always helps in a search. Thing is,
t-bird
never *used* to do this - it's only recently, I think....
