PT und bommel 2018-02-09 bauen nach der Doku Server/Jails/SRS14.

Installation

pkg update
pkg install apache24 maildrop sudo

Mailman und Postfix muss aus den Ports gebaut werden, weil die Paket sendmail als MTA unterstuetzt, wir aber Postfix benoetigen. Es gibt sonst Permission Probleme mit dem wrapper script.

#
# 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.

Um eine bessere Handhabung fuer die Daten (z.B. Mail Archive und Mailkonten) zu erhalten, werden diese in ein separates ZFS Dataset ausgelagert und dann in die Jail gehangen.
