# WebMonitor Standalone Module: mail
#
# CGI script for providing form and script
# to send mail to configured system users
#
# required files: mail.list
# Text file with users nicknames and
# email addresses in the format of
# <nickname>:<email address>
# Keep "mail.list" in same directory as mail script
# NOTE: you can even have group aliases!
# just separate the addresses with commas
# Make sure you 'chmod 0644 mail.list' so the server can read it
# +-----------------------------------------
# Example: |webmaster:admin@machine
# |john-doe:jdoe
# |carlos:cpero@ncsa.uiuc.edu
# |group:leader@domain.com,member@domain.com

# This script can be referenced 2 ways for the best flexibility:
#
# DIRECTLY, <A HREF="/cgi-bin/mail?nickname">
# This will generate an email form for the person named in 'nickname',
# and if they exist in the 'mail.list' file.
# If no 'nickname' is specified in the QUERY_STRING when the script is
# first invoked, or the nickname cannot be found in the 'mail.list',
# an email form with a SELECT box of all valid nicknames is generated.
# When the email form is submitted, it will call itself via method of POST,
# and send the email to the recipient, outputting a confirmation message.
# If the HTTP_REFERER was trasmitted when the script was first invoked,
# there will be a hyperlink available to go back to that page (such as
# the user's home page).
#
# FORWARDING RESULTS, <FORM METHOD="POST" ACTION="/cgi-bin/mail?nickname">
# This will forward the results from the FORM, which can exist anywhere,
# to the recipient specified by 'nickname'. Since the 'nickname' is in
# the QUERY_STRING, the FORM *must* use the METHOD="POST", otherwise the
# recipient's nickname will be blown away.
# Users may want to include a:
# <INPUT TYPE="hidden" NAME="next-url" VALUE="/~user/received.html">
# If this is present in the FORM input, the client will be redirected
# to this HTML file as a confirmation message instead of the default.
# In addition, the user can also define any of the following input names
# in their form to better customize the output mailed back to them.
# <INPUT TYPE="hidden" NAME="subject" VALUE="My survey results">
# <INPUT TYPE="hidden" NAME="from-name" VALUE="Average Web user">
# <INPUT TYPE="hidden" NAME="from-email" VALUE="jdoe@domain.com">
# These values will then be used in the header of the email message.
# Otherwise, default values will be substituted.
