# This module only handles receiving and sending out postings to a list.
# management of membership is handled by the favored command module
# - TLwebcommand, TLemailcommand, or both.
#
# we now import some functions from assorted libraries.
import sys, re, string, rfc822, smtplib, os.path
# someday we will collect each needed function
# and create a module just of those and distribute it
# with tinylist.
# make sure you set this to YOUR domain!
localhost = 'mydomain.foo'
# next line declares the path to stuff. DEFINE IT for *YOUR* server!
path = '/www/www.howlermonkey.net/cgi-bin'
# to the cgi-bin for your web dir,
# with no trailing '/'!
# note this tells TL where to start looking.
# everything is either here, or under this
# point in '/lists/' dir, mostly in '/lists/'.
# we read a command line arguement to determine the list name
listname = sys.argv[1]
# Arguement 0 is the name of the script run, 1 is the
# first arguement after that name in the command line,
# so this tells us the name of the email identity being addressed-
listname!
# variable 'incoming' receives the entire incoming message
# which is piped to the script on <stdin> which this reads by the alias
# such as:
# foolist:"|/pathtoprogram/programname foolist"
#incoming = raw_input.lines()
#I commented this out for the moment to see if this is better
# this block will contain the rfc822 decoding code when we get it
finished.
# Using rfc822.py, we digest the message and make parts available to the
program.
#message = rfc822.message(incoming)
incoming = rfc822.Message(sys.stdin)
pass
pass
pass
# end of dummycode. Hereafter we act as if it is decoded.
# The information is in the dictionary 'message', each item keyed with
the header's
# name. The BODY of that dictionary is in the string 'msg'. So are any
attachments.
sender = Message.getAddr("From") # we must dig
out the 'from: ' field contents
# Note we already know who it is TO - 'listname' !
# Remember, the mail ssytem fed it here with a command
# line arguement, after sorting it out to a known identity,
# so the list's defining alias contains that info.
# Strip whitespace chars off every element in the list passed to this
function.
def gangstrip(str): # ok, everybody
STRIP!
index = 0 # initiate
counter=0
while index<len(str): # define loopp
terination
str[index]=string.strip(str[index]) # and strip each
element.
index=index+1 # increase the
index pointer
# ok, let's read that membership file. it is named (listname) with no
name extension.
a.open(path + "/lists/" + listname,
'r')
members = a.readlines() # read all of it
in.
a.close() # and close the
file
# then we look to see if that FROM exists in the membership.
# clean it up;
gangstrip(members) # strip all leading and trailing whitespace
# from each element in the list
'members'.
# then we look to see if the sender is a member of the list:
if sender in members : # IF the sender is in the subscriber file,
subject = '[' + listname + ']' + subject # then accept
the submission.
if os.path.exists(path + "/lists/" +listname +".replyto"):
Reply_to = "Reply-to: " + listname + "@" + localhost +
CRLF # set the optional
else: # Reply-to:
field.
Reply_to = "" # if not, this
string
# is NULL.
XLoop = "X-Loop: " + listname + "@" + localhost # This breaks
email
# loops from
forming
# need to add something to detect these to STOP such posts!
if os.path.exists(path + "/lists/" + listname + ".footer"):
# if there is a
# footer, read it!
ftr = open(path + "/lists/" + listname + ".footer",'r')
# read the footer
# file
footer = ftr.readlines()
# into 'footer'
#
ftr.close()
# close that file,
msg = msg + footer + CRLF
# and append it to
# the message.
if os.path.exists(path + "/lists/"+listname+".random"):
# if this list has a random
# rotation file,
f1=open("./lists/"+listname+".random",'r')
# Open the random footer
# rotation file
randomline=gangstrip(f1.readlines())
# load the contents of the
# rotation
f1.close()
# then close the file
msg = msg + randomline + CRLF
# and add the random element
# to the footer.
# this end processing for an acceptable posting. Next block handles
process for
# REJECTED postings.
else: # BUT IF
THEY ARE NOT...
listnamemembers = sender # put
poster address as the
#
recipient in list
#
'listnamemembers'
msg = "" # and
clear the mesage.

#From:tinylist@mydomain.foo!
Subject = "Subject: Unauthorized posting to list: " + listname +
