Hi,
today I played a bit with X-Face header and a patch for sqwebmail has bee
created. It turns out to be actually simple and not too hard to create
after I did some digging in the code.
It is not yet in final shape, but it works, is usable as a proof of
concept. I use external X-Face convertor for this, publicly available.
I would like to get feedback on this.
Ugh, there's a reason why sqwebmail refuses to display images on external
web sites that are linked from HTML mail. And that's exactly what this
does.
There's just no fundamental way to do this with complete security, unless
sqwebmail itself downloads the image via HTTP, and has complete control of
the HTTP headers in the image request. It's fine to do this in standalone
mail or news clients, but this is a completely different situation here.
And even with standalone clients there are still some potential problems
here, with revealing one's IP address, should this web site get hacked.
I agre with this, what I need to get is something else.
To put it in another words - I used external XFace convertor I can't write it
myself. I did first test with /cgi-bin/xface2png script, but it did not the
actual conversion, I just verify I can get header to convert in the right
shape to process.
As a related, I could not find place where inline/attachment images are
extracted for download. I mean, their URLs looks something like
http://server/cgi-bin/webmail/login/milan/EC4F99FF139F596BFF3ACA5015974C40/1198312584?folder=INBOX&form=fetch&pos=4&mimeid=1.2
I could use slightly modified version, such as
http://server/cgi-bin/webmail/login/milan/EC4F99FF139F596BFF3ACA5015974C40/1198312584?folder=INBOX&form=fetch&pos=4&mimeid=xface
or something similar, but I did not find where this mime part is
processed/extracted/decoded to binary. Could you point me to the right place?
As a result, using either path, there will be no external reference. Would you
consider it then acceptable? That's the final question ;)
Regards,
Milan
