Mailman 2.1 has served its purpose at work for several years. Python 2 is at its end of life in FreeBSD. It’s time to move on to Mailman 3 and Python 3, or to Sympa if I’m unsuccessful in getting Mailman 3 up & running. I’ll try and document each step along the way.

Note, this is a long and dull blog entry. I’ll summarize this gig in another blog post when everything works as planned.

Parallel to my own efforts, Dan Langille (dvl@) is attempting to get Mailman 3 working for the FreeBSD project. I’ll be leaning on most of his work, e.g. r556421, r556422, and this.

I started by creating a new, dedicated VM almost 7 weeks ago. It has been given 4 vCPUs and 8 GiB of memory. It uses a 17 GiB virtual disk for boot and swap partitions; 512K legacy boot partition, 128M UEFI system partition, and 16G swap partition. The root pool is configured as raidz1 stretching over 3 virtual disks, each of 12 GiB, yielding roughly 35G. A dedicated data pool is configured as raidz1 stretching over 3 drives, each of 2 GiB, yielding roughly 5G. All disks are GPT partitioned and uses GPT labels for every partition.

xbd0 aka ada0:

1   freebsd-boot       40     1024 gptboot0
2            efi     1064   262144 esp0
3   freebsd-swap   263208 33554432 swap0

xbd1 aka ada1:

xbd2 aka ada2:

GPT 128
1   freebsd-zfs       40 25165744 lists_zroot1

xbd4:

GPT 128
1   freebsd-zfs       40 25165744 lists_zroot2

xbd5:

GPT 128
1   freebsd-zfs      40 4194224 lists_zdata0

xbd6:

GPT 128
1   freebsd-zfs      40 4194224 lists_zdata1

xbd7:

GPT 128
1   freebsd-zfs      40 4194224 lists_zdata2

(The virtual DVD drive is mapped to xbd3 in case you were wondering.)

I might redo the root pool as it has been given way too much storage.

To keep the user data separated from the system, the dedicated zpool named lists_zdata will store these filesystems (and possibly more):

  • /home
  • /usr/local/mailman
  • /usr/local/www
  • /var/db/postfix
  • /var/db/postgres/data11
  • /var/db/postgres/data11/base
  • /var/db/postgres/data11/pg_wal
  • /var/spool/clientmqueue
  • /var/spool/mqueue
  • /var/spool/postfix
  • /var/spool/sympa

The VM has these ports installed:

Webserver and certificate management:

  • www/apache24
  • security/py-certbot@py37

Postfix as the MTA instead of sendmail from base:

  • mail/postfix

Mailman 3 & friends:

  • mail/mailman3@py37
  • www/py-postorius@py37
  • www/py-gunicorn@py37
  • devel/py-importlib-resources@py37
  • mail/py-authres@py37
  • mail/py-authheaders@py37

Sympa & friends:

  • mail/sympa
  • databases/postgresql11-client
  • databases/postgresql11-contrib
  • databases/postgresql11-server

(I’ll take the leap to PostgreSQL 13 in early spring 2021.)

For sysadmin tasks:

  • misc/amanda-client
  • shells/bash
  • devel/cvs+ipv6
  • editors/emacs@nox
  • devel/gdb
  • sysutils/htop
  • net-mgmt/iftop
  • sysutils/lsof
  • sysutils/lsop
  • misc/mc-nox11
  • sysutils/ncdu
  • net-mgmt/net-snmp
  • security/rkhunter
  • sysutils/parallel
  • sysutils/psmisc
  • sysutils/screen

For communicating back to the mothership^Whypervisor:

  • sysutils/xe-guest-utilities
  • sysutils/xen-guest-tools

All packages are built from the ports tree by our resident builder.

The Mailman 3 Pre-Installation Guide and subsequent chapters will undoubtly be handy along the way.

I got sidetracked too many times today to do anything useful beyond writing the initial part of these notes. Maybe I’ll fare better tomorrow.


2020-12-02

I ran these two commands and got myself a surprise:

# cd /usr/local/mailman
# mailman info

During handling of the above exception, another exception occurred:

pkg_resources.DistributionNotFound: The 'zope.interface>=5.0' distribution was not found and is required by mailman

I have an old version of zope which is strange since the installed zope packages got pulled in by mail/mailman3@py37 and security/py-certbot@py37:

# pkg info -r py37-zope\*

py37-zope.schema-4.2.2_1:
	py37-zope.configuration-4.1.0

This doesn’t look too well until the ports tree is updated to support zope>=5.0.

As suggested by Dan Langille, I changed /usr/local/lib/python3.7/site-packages/mailman-3.3.1-py3.7.egg-info/requires.txt to accept zope.interface>=4.0:

It’s getting late, so I’ll continue tomorrow.

Running mailman info last night populated /usr/local/mailman with directories and files, including /usr/local/mailman/etc/mailman.cfg. The latter has only a few comments:

# AUTOMATICALLY GENERATED BY MAILMAN ON 2020-12-02 22:02:09 UTC
#
# This is your GNU Mailman 3 configuration file.  You can edit this file to

#
# For example, uncomment the following lines to run Mailman in developer mode.

Poking around led me to the MAILMAN_CONFIG_FILE environment variable.

GNU Mailman 3.3.1 (Tom Sawyer)
Python 3.7.9 (default, Oct 15 2020, 08:08:23)
[Clang 10.0.1 (git@github.com:llvm/llvm-project.git llvmorg-10.0.1-0-gef32c611a
config file: /usr/local/mailman/etc/mailman.cfg
db url: sqlite:////usr/local/mailman/data/mailman.db
devmode: DISABLED

Now there’s a slight improvement. Maybe we can now try to start the Mailman service.

Hum. It looks like ownership of files and directories is an issue.

Without any further configuration, Mailman 3 wants to use Postfix as the MTA. Should I add Postfix to the mix or try to convince Mailman to use sendmail from base? Judging by Hooking up your mail server, ditching sendmail in favour of Postfix seems reasonable.

Upon reading D14126, I noticed service mailman info. I decided to empty /usr/local/mailman, add mailman_enable="YES" to /etc/rc.conf and run the command.

# service mailman info
Usage: mailman [OPTIONS] COMMAND [ARGS]...
Try 'mailman -h' for help.

Error: Invalid value for '-C' / '--config': File '/usr/local/mailman/etc/mailman.cfg' does not exist.

Huh? What a tangled web we weave. Onwards!

Apart from the empty configuration file, everything in /usr/local/mailman are exactly as they were last night. Let’s try to start the service. Note, Postfix isn’t installed yet.

Let’s add Postfix to the mix.

# pkg install postfix

The following 1 package(s) will be affected (of 0 checked):

Number of packages to be installed: 1

The process will require 7 MiB more space.

Proceed with this action? [y/N]: y

===============================================================
Postfix was *not* activated in /usr/local/etc/mail/mailer.conf!

To finish installation run the following commands:

  mkdir -p /usr/local/etc/mail
  install -m 0644 /usr/local/share/postfix/mailer.conf.postfix /usr/local/etc/mail/mailer.conf
===============================================================

=====
Message from postfix-3.5.8,1:

--
To use postfix instead of sendmail:
  - clear sendmail queue and stop the sendmail daemons

Run the following commands to enable postfix during startup:
  - sysrc postfix_enable="YES"
  - sysrc sendmail_enable="NONE"

If postfix is *not* already activated in /usr/local/etc/mail/mailer.conf
  - mv /usr/local/etc/mail/mailer.conf /usr/local/etc/mail/mailer.conf.old
  - install -m 0644 /usr/local/share/postfix/mailer.conf.postfix /usr/local/etc/mail/mailer.conf

Disable sendmail(8) specific tasks,
add the following lines to /etc/periodic.conf(.local):
  daily_clean_hoststat_enable="NO"
  daily_status_mail_rejects_enable="NO"
  daily_status_include_submit_mailq="NO"
  daily_submit_queuerun="NO"

If you are using SASL, you need to make sure that postfix has access to read
the sasldb file.  This is accomplished by adding postfix to group mail and
making the /usr/local/etc/sasldb* file(s) readable by group mail (this should
be the default for new installs).

We need to do some housekeeping. I edited /etc/rc.conf and /etc/periodic.conf as instructed.

# less -S /usr/local/etc/mail/mailer.conf
/usr/local/etc/mail/mailer.conf: No such file or directory
# install -m 0644 /usr/local/share/postfix/mailer.conf.postfix /usr/local/etc/mail/mailer.conf
install: /usr/local/etc/mail/mailer.conf: No such file or directory
# mkdir -p /usr/local/etc/mail
# install -m 0644 /usr/local/share/postfix/mailer.conf.postfix /usr/local/etc/mail/mailer.conf

While the correct instructions was displayed initially, we were also presented with some half-baked instructions further down the line.

Anyway, what does Mailman think of this new addition?

# service postfix start
postfix/postfix-script: starting the Postfix mail system
# service mailman restart
Restarting the Mailman runners

This looks very promising, no error messages. Here’s the process tree:

Let’s create the initial list.

# mailman create --language no --owner postmaster@[REDACTED] -no-notify mailman
Error: Illegal list name: mailman
# mailman create --language no --owner postmaster@[REDACTED] -no-notify mailman@lists.[REDACTED]
Created mailing list: mailman@lists.[REDACTED]

Note, the name of the list is its posting address, and there is only one leading hyphen in -no-notify. The latter must be a bug in Mailman 3.3.1.

These are more or less the defaults as shown by mailman conf:

[ARC] authserv_id:

These are the settings that must be changed or emphasized in my opinion:

  • [mailman] default_language: no
  • [mailman] layout: home
  • [mailman] site_owner: postmaster@[REDACTED]
  • [mta] remove_dkim_headers: yes
    (I hope FreeBSD’s future mailling list system will strip away DKIM headers.)

In other words, /usr/local/mailman/etc/mailman.cfg should end up looking like this:

[mailman]
default_language: no
layout: home
site_owner: postmaster@[REDACTED]

[mta]
remove_dkim_headers: yes

Postfix must be able to relay received mail over to Mailman. Thus, /usr/local/etc/postfix/main.cf must be changed accordingly:

I admit I’m in unknown territory. Maybe simply the format of /usr/local/mailman/data/postfix_lmtp is foreign to Postfix. At this point I’m able to send and receive mail. The next step is the web interface(s) for easier administration and for mail archives.

It sure helps to follow the MTA guide, so this is how Postfix’ main.cf configuration file differ from the sample file.

I wonder if I can find a description of the Python object representation of each list. Right now I feel I’m ready to edit some settings.

The to-do list include:

  1. Get Postorius up & running.
  2. Get some kind of archiver, maybe HyperKitty, up & running.
  3. Get rid of footer_uri (previously known as msg_footer).
  4. Adjust other parameters of each list.
  5. Add members to each list.
  6. Inform the users on how to proceed from here.
