Mailman update

The prior version of this page is no longer applicable to these servers. I have also installed MM 3 on a third server. I have now evolved my process and installations to a stable point. It is this configuration that I will describe. Preliminaries Both lm3o and mpo already had sass and memcached installed via apt install ruby-sass apt install memcached I installed these on the third server. Also, lm3o and mpo are both Ubuntu It turned out that I also couldn't install libapache2-mod-wsgi-py3 on mpo via apt because that installed a Python 3.

After some months, on mpo, Apache was upgraded by an automatic upgrade. However, before this was diagnosed, I switched mpo to use Gunicorn with Apache. The third server is Ubuntu Installation For these installs, I opted to install the entire Mailman suite in a virtualenv. The biggest motivation for this choice was the fact that there are already production lists on both servers and using a virtualenv allowed me to do a lot of the work in advance without interfering with the production install.

Possibly influenced by these experiences, I am now using virtualenv for all installs. Note that all of this is done as the mailman user. On the third server I have added mailman-suite because I use the settings. I then activated the virtualenv and did pip install psycopg2-binary pip install pylibmc pip install Whoosh on both servers. Set this to some number great than 0 and Mailman will close the SMTP connection and re-open it after this number of consecutive sessions. If your Python interpreter was not built for threads, this feature is disabled.

After this period of time, a message that has failed recipients will be dequeued and those recipients will never receive the message. Getting this right is critical — and tricky. Learn your Python regular expressions. It must define exactly three named groups, bounces , local and domain , with the same definition as above. It will be compiled case-insensitively.

However, because it can be a significant performance hit, we allow you to decide how often to VERP regular deliveries. This is the interval, in number of messages, to do a VERP recipient address. The same variable controls both regular and digest deliveries. This limit prevents response loops between Mailman and misconfigured remote email robots.

This is a fallback safety valve so it should be set fairly high. Set to 0 for no limit probably useful only for debugging. Various list transformations to the message such as adding a list header or footer or scrubbing attachments or even reply-to munging can break these signatures. It is generally felt that these signatures have value, even if broken and even if the outgoing message is resigned. The path can be either a file system path or a Python import path. If the value starts with python: then it is a Python import path, otherwise it is a file system path.

File system paths must be absolute since no guarantees are made about the current working directory. Python paths should not include the trailing.

To enable, set this to yes. Mailman can do these check on its own, but if you already perform these checks earlier in your pipeline, say via a milter previous to Mailman, they can be used instead, as long as you specify your domain as a trusted domain below. If those checks are not placed in an Authentication-Results header from a trusted domain they will be ignored. Inclusion of the From header is mandatory. The value is the name of an existing style. If no such style exists, no style will be applied.

RFC also specifies these headers in this exact order, so order matters. These are space separated and case insensitive. Leave these blank if no authentication is necessary.

Leave these blank to use the default localhost Any second and subsequent headers are rewritten to the second named header case preserved. This is a list of header pairs, one pair per line. This controls how often gatenews is run. The time to wait for a response from a name server before timeout.

This can be anything handled by the Python urllib. This file is part of GNU Mailman. This is the GNU Mailman configuration schema. It defines the default configuration options for the core system and plugins. It uses ini-style formats under the lazr. Certain messages which must be delivered to a human, but which can't be delivered to a list owner e.

Mailman will append ' ' and the host name of the list involved. Many headers are removed from posts to anonymous lists before this is consulted, but of the remaining headers, any that don't match one of these patterns are also removed. See the IPlugin interface for more details.

The full Python import path for you IPlugin implementing class. It is required to provide this. If not given, the plugin's name is used.

Use --help for more information. Customize the interpreter prompt. Use IPython as the shell, which must be found on the system. Problem description: A server running Mailmain versions prior to 2. This data may contain scripts which will then be executed by an unwary client, possibly transmitting private information to a third party.

The Common Vulnerabilities and Exposures project cve. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied.

To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade.

Choose 2 if yes which is what I recommend doing. That's it! We are now ready to install Postfix because after all, Mailman 3 needs to send out mail. Mail Server Installation: Postfix 1.

Ok, we are now ready to install Postfix. The first thing we do here is install mailtuils: apt install mailutils Now we install Postfix: apt install postfix 2. Now you will be presented with an interactive dialogue: General type of mail configuration: Internet Site System Mail Name: server hostname 3.

Let's configure Postfix now. Time to apply the changes: systemctl restart postfix 9. The final step is to allow postfix through the firewall: ufw allow postfix Now you have a working SMTP server and it's time to install and set up a database server for Mailman 3. Database Server Installation: Postgres 1.
