Ok here's the walkthrough:
The message quotes "Upon the Looking Glass", if you google that, the second result points a torrent at thepiratebay.
If you download the torrent there are 2 files, a "*** BURNME ***.dmg" and a "*** README ***.bf" file.
The "*** README ***.bf" file is (of course) a bf file that can be read by a bf interpreter (sorry for the redundancy). There's an online bf interpreter, input that file and you'll get the string "SECURELOL", that's the password for your DMG file "*** BURNME ***.dmg".
If you mount the DMG file, you'll see 2 folders, a VIDEO_TS and a AUDIO_TS folder, those are the characteristics of a common DVD. You can open a VIDEO_TS DVD folder in VLC (http://www.videolan.org/vlc/), if you open it you'll get a video that says "mac.mirroredperspectives.com".
Go to http://mac.mirroredperspectives.com, you'll see an iMac that gets mirrored infinite times, if you access the site from Internet Explorer, there are Internet Explorer browsers in the image, if you open it from Safari/Firefox for Mac, you'll see Safari browsers in the image, so, by common sense, the oposite of mac is windows isn't it? so access http://win.mirroredperspectives.com from a Windows PC, you'll get the same effect image but with a CRT monitor instead of the iMac, also there's a little minesweeper icon, click it to download a ZIP file.
The ZIP file contains a dashboard widget (Mac only), open it and solve the minesweeper, you'll get this message: http://clementine.quickshareit.com/shar … 246af7.jpg (not an official link, just a mirror of the message).
Scorpio, Libra and Pisces are mentioned in the message, so in the DVD if you match the sign with its planet (scorpio with mars, libra with jupiter (zeus), and pisces with neptune (seas)) gives three words: seventh enchanted reflection, ergo, http://seventhenchantedreflection.com
Go to the page, there are 6 dices, by trial and error select the correct combination, being 6135, that's NOT the code, if you look at the dice in a mirror, what will you get? 1462, the pass for http://backdoor.macheist.com.
