PHP E-mail Parser

This is a fairly simple and lightweight script written to parse an e-mail. This script attempts to find the "To", "From", "Subject", and "Date" headers, along with, of course, the body. It can handle both text and HTML e-mail. It is able to detect and decode base-64 and quoted-printable subjects, as well as quoted-printable e-mail bodies. It can take anything as input, and the input variable is clearly marked. It does not currently support attachements, however it can be easily modified to do so. This is the same e-mail parser used at SpamLot, a disposable e-mail site run by D. Strout. You can find it at the demo link, instructions are on the site.
