README mlmmj-1.2.17 Jan 23rd 2010 This is an attempt at implementing a mailing list manager with the same functionality as the brilliant ezmlm, but with a decent license and mail server independency. The functionality: · Archive · Custom headers / footer · Fully automated bouncehandling (similar to ezmlm) · Complete requeueing functionality · Moderation functionality · Subject prefix · Subscribers only posting · Regular expression access control · Functionality to retrieve old posts · Web-interface · Digests · No mail delivery subscription · VERP support · Delivery Status Notification (RFC1891) support To use mlmmj, do the following: 0) Compile it if you're not using a binary package such as dpkg, rpm or a ports collection from a BSD or Gentoo. To compile, untar the tar-ball and do: $ ./configure && make && make install If you want to filter multipart/mime messages, pass the option --enable-receive-strip to configure, and take a look at contrib/receivestrip/README. 1) Configure a recipient delimiter. The default is to use '+', and in Postfix it's done by adding recipient_delimiter = + to /etc/postfix/main.cf. In Exim it can be done by adding local_part_suffix = +* local_part_suffix_optional to the "userforward:" and the "localuser:" router in /etc/exim/exim.conf, and also add "local_part_suffix = +*" to the system_aliases function. Also make sure that exim will add the envelope from in the Return-Path: header. There is a nice FAQ explaining recipient delimiter configuration here: http://faqs.org/faqs/mail/addressing/ The mlmmj TUNABLE "delimiter" configures this on a per list basis NOTE: Using '-' as a delimiter is unlikely to work. Mlmmj uses '-' as its own kind of minor delimiter. Of course, you also cannot use the delimiter in your list names or you will encounter problems. 2) Create the mailinglist. There's a script, mlmmj-make-ml, that will make a mailinglist for mlmmj. It is highly recommended to use this script to make the lists! What is does is described here: In the case of a list called mlmmj-test below /var/spool/mlmmj it makes the following directories: /var/spool/mlmmj/mlmmj-test/incoming /var/spool/mlmmj/mlmmj-test/queue /var/spool/mlmmj/mlmmj-test/queue/discarded /var/spool/mlmmj/mlmmj-test/archive /var/spool/mlmmj/mlmmj-test/text /var/spool/mlmmj/mlmmj-test/subconf /var/spool/mlmmj/mlmmj-test/unsubconf /var/spool/mlmmj/mlmmj-test/bounce /var/spool/mlmmj/mlmmj-test/control /var/spool/mlmmj/mlmmj-test/moderation /var/spool/mlmmj/mlmmj-test/subscribers.d /var/spool/mlmmj/mlmmj-test/digesters.d /var/spool/mlmmj/mlmmj-test/nomailsubs.d /var/spool/mlmmj/mlmmj-test/requeue NOTE: The mailinglist directory (/var/spool/mlmmj/mlmmj-test in our example) have to be owned by the user the mailserver writes as. On some Postfix installations Postfix is run by the user postfix, but still writes files as nobody:nogroup or nobody:nobody 3) Make the changes to your mailserver aliases that came as output from mlmmj-make-ml. Following the example above they will look like this: mlmmj-test: "|/usr/bin/mlmmj-receive -L /var/spool/mlmmj/mlmmj-test" NOTE: Don't forget newaliases. 4) Start mlmmj-maintd (remember full path when starting it!) or add it to crontab with -F switch. The recommended way for now is to run it via cron: "0 */2 * * * /usr/bin/mlmmj-maintd -F -L /var/spool/mlmmj/mlmmj-test" It should be started as root, as mlmmj-maintd will become the user owning the listdir (/var/spool/mlmmj/mlmmj-test), and log it's last maintenance run to listdir/mlmmj-maintd.lastrun.log. If you have several lists below /var/spool/mlmmj you can use -d: /usr/bin/mlmmj-maintd -F -d /var/spool/mlmmj If you have lists more deeply nested below /var/spool/mlmmj, use something like: find /var/spool/mlmmj -mindepth 1 -maxdepth 1 -type d \ -exec /usr/bin/mlmmj-maintd -F -d {} \; That's it! You probably want to go through the next steps too. 5) Subscribe some people /usr/bin/mlmmj-sub -L /var/spool/mlmmj/mlmmj-test/ -a joe@domain.tld etc. 6) If you want custom headers like X-Mailinglist, Reply-To: etc. just add a file called 'customheaders' in the list control/ directory like this: $ cat /var/spool/mlmmj/mlmmj-test/control/customheaders X-Mailinglist: mlmmj-test Reply-To: mlmmj-test@domain.tld 7) If you want every mail to have something like: -- To unsubscribe send a mail to coollist+unsubscribe@lists.domain.net Just add what you want to a file named "footer" in the same dir as "customheader" (listdir/control/). 8) If you want a prefix on the subject, to make it look like this: Subject: [mlmmj-test] how are we doing? Simply do 'echo "[mlmmj-test]" > control/prefix 9) For having a moderated list, simply create a file called 'moderated' in the control/ directory. Moderators are added to a file called 'moderators' in the control/ dir as well. 10) Have a look at the file TUNABLES for runtime configurable things. Tunables in include/mlmmj.h: · There's some time intervals for how mlmmj-maintd operates. I've choosen non-strict defaults, so depending on your BOFH rate you might want to tweak. The defaults should be good for most people though. Have fun! Mads Martin Joergensen <mmj at mmj dot dk> Morten K. Poulsen <morten at afdelingp dot dk>
