#
# An example script that intercepts email messages
# and processes them in some fashion.
#
# Setup:
# in 220a account, create .forward file with this single line
#
# "|/usr/bin/python /Users/classes/220a/bin/parseMail.py", \220a
#
# First part indicates that message body should be 'piped' to the
# python program parseMail.py in ~220a/bin.  Second part says that
# a copy of the message should be kept in mailbox of User 220a.
#
# This script appends the date, subject, sender, and body of the
# message to a file in ~220a/uploads called filtered.mail.txt.
# (uploads does not need to be world writable.)
# 
# Main Reference: http://docs.python.org/library/email-examples.html
