Ok, this is not an argument! > So this is really a non-issue. So, to sum up what I've learned till now: If attachements are inlined via an iframe, only a few file types will get considered, the other file types will just result in an empty frame. The valid file types are being handled by a viewer. Only a few types are considered secure and therefore built-in to be displayed. But others can be configured as well via the user instransparent gconf interface (i.e. there's no way for the user to fastly check which file types are being considered). (Think preconfigured evolution packages.) Ok, is seems to be pretty secure this way, but I just don't like the intransparencies of the chosen method. But I know that evolution should also be easily configurable by the novice, so it seems to be a trade-off between ease of use and feature-rich configurability, which some of us like to have. All in all, it would be nice if there would just be a config option to turn off automatic display of inlinded content or just any (non-textual) content (no, not a fully featured text display to replace the html view, but just an option to turn off the call of any viewer). > -- Dan > > On Sat, 2003-08-16 at 09:38, Andreas W�st wrote: > > Hi > > > > Thanks for your answer! > > > > On Fri, 2003-08-15 at 02:21, Not Zed wrote: > > > > > I might also add that this is functionality is absolutely required to > > > implement html email. e.g. the introduction email that comes with > > > evolution. > > > > > > Its up to the image library to handle it, so yes you could exploit holes > > > in libjpeg or gdk-pixbuf if they existed. > > > > > > The alternative is to only allow the display of text ... > > > > Wouldn't it be possible to use the html rendering widget only for the > > headers (just to get the nice box), the body of the mail gets displayed > > using a text box? > > > > Since the headers are being preprocessed anyway if you use full html > > rendering, you could simply reuse the header preprocessor method, and > > feed the rest of the mail to a text box. > > > > I am sorry I can't provide a patch for this., ;) > > > > > On Thu, 2003-08-14 at 14:13, Andreas W�st wrote: > > > > Hi > > > > > > > > Am I right that evolution doesn't seem to do no better than outlook when > > > > it comes to inlined data? > > > > > > > > If you get an email sporting a line like > > > > > > > > <img src="cid:blablabla";> > > > > > > > > and attached you get a file with a > > > > > > > > Content-ID: blablabla > > > > > > > > string, evolution tries to to display this stuff inline, no? > > > > > > > > And since most of these attachements are virus today, the user is no > > > > better off than an outlook user?! > > > > > > > > Please correct me, if this isn't so!
