# Description:
# This script is designed to check a list of Hotmail addresses
# for 'validity', that is, if the addresses are actually real and
# 'active'. The script does this without sending an test email to
# to the addresses. The script uses a java application 'checkhotmail.class'
# which sends a series of raw SMTP strings to the Microsoft Hotmail
# SMTP server and watches the responses.
#
#
# Notes:
# This script, as usual, took a large amount of time to get working. (probably about
# 4 hours, after the 'checkhotmail.class' java program had been written. This was because
# if various 'gotcha' mainly involving the way the lines are terminated in various
# environments. Especially the way taht the 'procgi' script interprets textarea newline
# characters is a little surprising.
#
# It is possible that this script running for a browser on a Unix type operating system
# will have some problems. This is because of some of the strange 'line ending' translations
# which have been done, and because of the '<pre>' tags used. (Although the man2html script
# which converts unix man pages to HTML also uses '<pre>' tags, so maybe they are not such
# a problem.
#
# In migrating from Debian to Redhat Linux, the following things had to be fixed: The
# path to the java executable had to be altered, and the directory in which the
# script resides had to be given 'write' permissions for 'others'.
# Ideas:
# Dependencies:
# checkhotmail.class

P L E A S E N O T E: This program does <em>not</em> send 'test' emails to the email
addresses which you
enter in the box below. The owners of the email addresses will <em>not</em> receive anything in their
inbox from this program.<br><br>
H I N T: The Hotmail email address that you 'cut-and-paste' into this text box
can be separated by semicolons (;) or commas (,) or spaces ( ) or they can be on separate lines or
you can use a combination of these techniques<br><br>
