#!/usr/bin/env python

#A simple test program for recieving and sending emails via python
#For others reading this please keep in mind i had to use AUTH PLAIN because i have saslauth
#on my server and no combinations of normal methods via smtplib would allow me to send mail.

#Verson 1
"""
I wrote the simple script for checking the status of the inbox

Verson 1.1
I added the part that connects checks the status and if there emails
it fetchs them displays them and delets them.

Version 1.2
Added support to email user back.  Added options for differnt auth
methods not supported by smtplib (i may be wrong)

Version 1.3
Emails back with proper MIME stuff.

Version 1.4
Phrases for subject and now can act upon it

Verson 1.5
Added help command which returns the conents of any file in help/

Verson 1.6
Added test command
