=== Probleme === | |||
Listen von einem bereits installierten Postfix schnell und sauber mit allen Einträgen in die Mailman-Software übertragen. | |||
==== Ansatz 1 (nicht getestet)==== | |||
Mit Hilfe einer Pythondatei (siehe weiter unten). | |||
Jede Liste im Postfix muss in eine extra Datei (Postfixlistendatei), welche in der Postfixdatei .../postfix/main.cf unter dem Punkt <code>alias_maps</code> verwiesen wird. Dann <code>newaliases</code>, anschließend erstellt man alle Listen im Mailman und führt in der Konsole die Datei <code>/usr/local/mailman/bin/newlist</code> aus. die im Anschluß aufgelisteten Codeschnipsel werden in die richtigen "Postfixlistendateien" kopiert. | |||

# 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. | |||
