Hmm, so the e-mails are routed through their infrastructure and then ( presumably ) some form of magic is injected and delivered to the recipient. Upon opening, the content 'fades-out' and fade.li assure us that they delete the content from their systems. /me tries with disposable account Aha, it renders the mail content as images. A bunch of basic HTML with the GIFs inline, I used wget to pull them down but the meta…

Freemium model appears to be allowing this else downloading can be easily stopped from wget and other downloaders. ofcourse screenshot is the option. ;)

You can't easily stop wget. It's impossible to distinguish between Firefox accessing the image, and wget / curl / whatever accessing the image with Firefox's user agent string (and changing the user agent string in these utilities is just a simple flag)

it scrolls trough the lines, so screenshotting that is difficult.

There are a few plugins for FF available that capture the whole screen. Not sure of any quirks though.

Not a plugin but a windows program (don't know if it works on win7, I run linux now) called faststone capture can move the scrollbar and take screenshots. The current version (7.6) is paid:

You could get clever by testing on the server whether the other headers are consistent with the User Agent (e.g. Accept).

neat tool: chrome developer tools > network > rightclick a resource > copy as Curl > paste on command line

allows you to replay a request, complete with all cookies and the exact same headers.

yeah, aware this isn't what's wanted here, single request image etc etc ... but relevant.

I did not realize you could setup a MX record for a wild-card subdomain. It would seem like there are lots of applications for that setup - how come it's not something I've seen dome more?
