This renderer is in BETA status. Do not use for security relevant purposes (yet). Comments and bug fixes are welcome.

After creating your one-time email address, you get one link to the original mbox and on link to the renderer, clearly labelled as beta. The lead developers want to remain anonymous for now.

anonbox.net offers a javascript in-browser mail renderer. This fetches your mailbox from the server via HTTP and splits it into seperate emails, parses the MIME encapsulation, decodes images so your browser can render them, converts attachments to data://-URIs, so you can view or download them on your computer and offers character set decoding tools so that all the weird charsets you get from mail clients all over the world can be rendered correctly by your browser. For the most extreme cases there's also a what-you-see-is-what-you-click mail header decoder.

In order to protect your anonymity, there's also some code preventing remote ressource including as with the src= tag. However this is a heuristic approach only and you should take additional care not to leak information.

In this mailbox you can see how multiple messages in your mailbox are handled. Click anywhere in the message headers to expand them. To view the message's source code, click on the "View this email's source"-button on the upper right to switch between content view and source view.

In this email there is two images and one pdf file attached. Click on the images to enlarge them, in modern browsers you also should be able to view and right-click-save the pdf attachment.

In this mailbox there are three types mails each showing images. The first sources an external image. You can make your browser fetch the image by clicking the "Load remote images"-Links right above the HTML frame.

In this mailbox there is a collection of emails with the strangest encodings that hit the developer's mailboxes. The parser tries to convert any text to unicode so that your browser understands it. Sometimes the encoding is hard to guess, so you can select from a drop down box of possible meanings by hitting the red "Seeing strange text?"-Button in the top right corner of the screen. Once you recognize letters you can understand, hit the button again and you can select and copy the text.
