#
# Script setup:
# -------------
#
# Change the first line of this file, if necessary. Either
# '#!/usr/local/bin/perl' or '#!/usr/bin/perl' should work on any unix
# system.
# Change the configuration part below as described below.
# Upload this file as ASCII to your cgi-bin and chmod it to 755, if
# you have a unix server.
# ( user: [x]read [x]write [x]execute
# group: [x]read [ ]write [x]execute
# other: [x]read [ ]write [x]execute )
#
#
# Form setup:
# -----------
#
# Required fields:
#
#
#
# The first line is the location of the mail script. The second line is the
# alias of the recipient as specified in %alias (see cofiguration below).
# With version 1.1 and higher you can specify as many recipients as you like.
# Just seperate them by comata (,). Do not use any blanks. Remember: Do not
# use real email addresses, but alias names! Example:
#
#
# Note that the alias stuff is a security feature to keep bad people
# from using the script as an anonymous remailer. Other form mailers
# use the referer mechanism to accomplish the same thing. This is not a good
# idea, because the referer information is provided by the client and can
# hence be easily faked.
#
# All other fields are optional, but i guess it would be a good idea to include
# some. :)
#
# Configuration fields:
#
# - linkURL
# This will be used for a link on the confirmation page. Default is
# your base directory /. Example:
# # value="http://your.server.com/you/index.html">
#
# - linkName
# This will be used as name for the link specified above. Default is 'home'.
# Example:
#
# - e-mail:
# The email address of your visitor. This will appear in the 'From' field of
# the messages header. Example:
#
# - name
# The realname of your visitor. This will appear in the 'From' field of the
# messages header. Example:
#
# - subject
# The subject of the message. This will appear in the 'Subject' field of the
# messages header. Example:
#
# - required
# Specifies required fields. The script will only send mail, if all
# required fields are filled out. Example:
#
#
# - empty_fields (v1.1)
# Determines wether empty fields should get mailed (yes) or not (no).
# Default option is no. Example:
#
#
# - order (v1.1)
# Determines the order of the form fields in the message. Seperate the form
# field names with a coma (,); do not insert blanks. All form fields that are
# not specified here will be mailed in a random order after the ordered ones.
# Example:
#
#
# - bgcolor
# Specifies the background color of the confirmation and error pages.
# Default value is white. Example:
#
#
# - color
# Specifies the font color of the confirmation and error pages.
# Default value is black. Example:
#
#
# - face
# Specifies the font face used for the confirmation and error pages.
# Default value is Arial. Example:
#
#
# - title
# Specifies the title of the confirmation page. Default value is
# 'message sent'. Example:
#
#
# - redirect
# Use it, if you want to use your own confirmation page. Example:
# # value="http://www.server.com/you/thank_you.html">
#
# All other form fields will get mailed to you. You can include as many
# as you like. Example:
# your homepage:
# will get mailed as
# [ hp: ]
# .... <--- here comes the user's input
#
# Don't forget to insert a submit button
# and to close the form tag with ... and maybe setup a link to my
# website , if you think that this script
# or my site is worth it ;)
#
# enjoy ... bernd

能在ASP的服务器上用吗

我觉得好像是PERL语言写的
它上面的"#"也有用吗

谁会把它改成ASP的
