# This script was originally qmail-to-mailman.py by:
# Bruce Perens, bruce@perens.com, March 1999.
# This is free software under the GNU General Public License.
#
# This script is meant to be called from ~mailman/postfix-to-mailman.py. 
# It catches all mail to a virtual domain, eg "lists.example.com".
# It looks at the  recipient for each mail message and decides if the mail is
# addressed to a valid list or not, and bounces the message with a helpful
# suggestion if it's not addressed to a list. It decides if it is a posting, 
# a list command, or mail to the list administrator, by checking for the
#  -admin, -owner, and -request addresses. It will recognize a list as soon
# as the list is created, there is no need to add _any_ aliases for any list.
# It recognizes mail to postmaster, mailman-owner, abuse, mailer-daemon, root,
# and owner, and routes those mails to MailmanOwner as defined in the
# configuration variables, above.
#
# INSTALLATION:
#
# Install this file as ~mailman/postfix-to-mailman.py
#
# To configure a virtual domain to connect to mailman, edit Postfix thusly:
#
# /etc/postfix/main.cf:
#    relay_domains = ... lists.example.com
#    transport_maps = hash:/etc/postfix/transport
#    mailman_destination_recipient_limit = 1
#
# /etc/postfix/transport:
#   lists.example.com   mailman:
#
# /etc/postfix/master.cf
#    mailman unix  -       n       n       -       -       pipe
#      flags=FR user=mailman:mailman 
#      argv=/var/mailman/postfix-to-mailman.py ${nexthop} ${user}
# 
#
# Replace list.example.com above with the name of the domain to be connected
# to Mailman. Note that _all_ mail to that domain will go to Mailman, so you
# don't want to put the name of your main domain here. Typically a virtual
# domain lists.domain.com is used for Mailman, and domain.com for regular
# email.
