#!/bin/bash # 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 '
' tags used. (Although the man2html script
#   which converts unix man pages to HTML also uses '
' 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'.

    P L E A S E    N O T E: This program does not send 'test' emails to the email 
    addresses which you
    enter in the box below. The owners of the email addresses will not receive anything in their
    inbox from this program.



    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



    please send questions to: matthew@ella-associates.org or matth3wbishop@yahoo.com
    

    Please enter (or cut-and-paste) the Hotmail Email Addresses which you wish to check
