# Description:
#   This script attempts to send an email using 'netcat' to the yahoo account
#   matth3wbishop@yahoo.com. This is to be used in circumstances in which using a 
#   normal mail server is not possible.
#
#   It has the disadvantage that a delay interval for 'netcat' is necessary.
#   This means that the script will take quite some time to return, which
#   may be unacceptable from a web-page for example. One solution is to 
#   run the script in the background with &, but thats a bit dodge.
#
#   The better solutions are to write or find a Java SMTP mail sender or
#   to set up a 'sendmail' program on the local server.
#
# Notes:
#   The script can only send mail to the 'localhost' because it does
#   no SMTP authorization, and therefore it can only send mail to somebody
#   who has a mail box on the local computer.
