before next release: disable backscatter in default installation
by Jo Rhett Nov. 7, 2022

Nov. 7, 2022

Hi. There's a fairly simple problem here that needs to be addressed. And it's mostly a documentation/install problem. I'm hoping we can get this resolved before the next release. PROBLEM: Mailman comes out of the box ready to backscatter spam people. Yes, it's easy enough to fix. But because it comes stock this way, and is documented to install this way, most people install it to do this. Those of us who work in abuse departments are tired of hearing "well that's how Mailman works". We also object to having to teach people how to fix their mailman installations because it's not documented in the current manual. This is *exactly* like Sendmail 14 years ago. We didn't accept it then, and Sendmail fixed the problem. RESOLUTION: Mailman default installation should not backscatter in a default configuration. 1. Don't create backscatter aliases for subscribe/unsubscribe/etc by default. Nearly everyone uses web based signup. 2. Discard or hold messages from non-subscribers by default. I would think that it would be perfectly reasonable to have documentation on how to enable the 1980s-style -request / -subscribe etc aliases. However this documentation should have a note that this is against the AUP of nearly every network provider, and enabling it will likely cause them to get listed in various blacklists as a backscatter source. FYI: I know that this goes against the instincts of many old-time mailing list advocates here. But after dealing with a 10k/hour backscatter DoS my tolerance for this problem is understandably limited. Yes, it was a sweet day back in the 1980s. I was running a mailing list server and several UUCP gateways at the time, so I remember them well. But those days are past, and we need to deal with the reality of today. -- Jo Rhett Net Consonance : consonant endings by net philanthropy, open source and other randomness

Alembic not going back to previous migration?
by Aaryan Bhagat June 28, 2019

June 28, 2019

Currently, I am working on [this](https://gitlab.com/mailman/mailman/merge_requests/528) PR. A problem arose with some SQLite tests and I made changes to the latest migration file. This is my output of `alembic -c src/mailman/config/alembic.cfg history` command >2d2d0ef0828f -> 58858f75303c (head), Added new bounce attributes >15401063d4e3 -> 2d2d0ef0828f, add tag column >b2e694dfde35 -> 15401063d4e3, roster_visibility >89913992dd5a -> b2e694dfde35, unique email contraint >dfe82cf73702 -> 89913992dd5a, remove mime_is_default_digest >3f31035ed0d7 -> dfe82cf73702, add_alias_domain >4bd95c99b2e7 -> 3f31035ed0d7, further_increase_pendedkeyvalue_value_size >3002bac0c25a -> 4bd95c99b2e7, Fix template password field. >a46993b05703 -> 3002bac0c25a, dmarc_attributes >448a93984c35 -> a46993b05703, increase pendedkeyvalue value size >fa0d96e28631 -> 448a93984c35, unsubscription_workflow >7b254d88f122 -> fa0d96e28631, File cache and template manager. >d4fbb4fd34ca -> 7b254d88f122, Members and list moderation action. >bfda02ab3a9b -> d4fbb4fd34ca, Add a numerical position column to sort header matches. >781a38e146bf -> bfda02ab3a9b, Ban indexes >70af5a4e5790 -> 781a38e146bf, MailingList indexes >47294d3a604 -> 70af5a4e5790, digests >3e09bb4a5dc -> 47294d3a604, Pendable indexes >33bc0099223 -> 3e09bb4a5dc, Add indexes on the Member table. >42756496720 -> 33bc0099223, Add member indexes >2bb9b382198 -> 42756496720, header_matches >16c2b25c7b -> 2bb9b382198, Workflow state table >46e92facee7 -> 16c2b25c7b, List subscription policy >33e1f5f6fa8 -> 46e92facee7, add_serverowner_domainowner >51b7f92bd06c -> 33e1f5f6fa8, Migration from Python 2 to Python 3. ><base> -> 51b7f92bd06c, Initial migration.

It gives a long traceback, the main gist of which is >sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) duplicate column name: bounce_info [SQL: 'ALTER TABLE address ADD COLUMN bounce_info BLOB'] (Background on this error at: >http://sqlalche.me/e/e3q8) The whole traceback is [here[(https://gist.github.com/berserker1/6b214626042a6c976f780b33d2d12f32) I did `alembic -c src/mailman/config/alembic.cfg downgrade 2d2d0ef0828f` to ensure it has restored to the previous version but still, again the error pops up Basically, Alembic is not able to properly downgrade and hence recognising a duplicate column when I upgrade. Any pointer to this would be helpful.

GSoD 2019: Issue in submitting proposal
by Ananya Maiti June 28, 2019

June 28, 2019

Hi GSoD '19 mentors, Google is accepting proposal responses in a google form this time and is asking to add the proposal content in the description field of the google form [1] . I updated my proposal after initial review and then got a "Response is too large" error while submitting, I have emailed gsod-support and also posted in their slack channel. But still didn't get any reply. Currently the response has the initial draft of my proposal before the review. Since the issue is related to the content size and the deadline is also tomorrow, do you have any suggestion regarding this? Should I shorten my proposal content or if I can omit sections which are not highly important like Personal Information, Resume links, Reason why I am apt since quite many of these information is available in the form responses ? Thanks, Ananya

Archive entry not created on creating list in development environment
by Ananya Maiti June 26, 2019

June 26, 2019

Hi all, I am trying to test a local installation of mailman suite. I have set-up mailman suite using instructions from [1]. I have also setup postfix as the mail server. Also I have added the absolute path to mailman-hyperkitty.cfg to maiman.cfg in my local setup. But when I create a list from postorious web ui a record for the same is not created in hyperkitty. I have to manually add a record for the same from the Django admin interface. Is this expected ? If not do I have to add any additional setting to get the behavior.

Mailman still sending mails when `DEVMODE` is on?
by Aaryan Bhagat June 25, 2019

June 25, 2019

Currently, I have been trying to run a working instance of Mailman up and running. I have edited the `mailman.cfg` file enabling devmode. The current output of `mailman info` command is the following >GNU Mailman 3.2.3 (La Villa Strangiato) >Python 3.7.1 (default, Dec 14 2018, 19:28:38) >[GCC 7.3.0] >config file: /home/aaryan/mailman/mailman-suite/mailman-suite_project/var/etc/mailman.cfg >db url: sqlite:////home/aaryan/mailman/mailman-suite/mailman-suite_project/var/data/mailman.db >devmode: ENABLED >REST root url: http://localhost:8001/3.1/ >REST credentials: restadmin:restpass Still, after when I created the `superuser` and tried to log in after as superuser after hosting up a local instance, it says >Verify your email address >We have sent an e-mail to you for verification. Follow the link provided to finalize the signup process. Please contact us if you do not receive it within a few minutes. This should not be the expected behaviour in devmode right? It should bypass this I believe. Am I missing something here?

Google's Season of Docs - An Introduction
by Burton Samograd June 25, 2019

June 25, 2019

Hello, Google's Season of Docs is here and I'm thinking I will try and participate. https://docs.google.com/forms/d/e/1FAIpQLSdGDY4LC_7OknP2zi90JTkH0qDrCm1AQFi… I've got my eye on the MailMan program as of now, something I think is a very powerful way to manage email lists using standard tools. Often the best note system is to write to yourself. Or maybe some other personas. MacOS has postfix installed by default, did you know what? Imagine a swarm of messages going to different accounts on the same system. Internal messaging system, powered by working software with no arbitrary limits and resources as the signalling system. Now that's an extenable, high level messaging system similar to the plumbing system on plan9. Having a high level interface for that might be interesting. Now I wonder if .forward files work with pipes in postfix on MacOS by default… I will be looking over the pages more thoroughly with regards to what is wanted to be documented this year, but I thought I would introduce myself.

Rich Text support in Hyperkitty
by Abhilash Raj June 22, 2019

June 22, 2019

Hi All, I have been recently working on adding rich text support through markdown in Hyperkitty so that emails can be made easier to read. The core design idea in my mind when working on this was building something that doesn't bother writers of plain text emails too much, but allows people to write emails in markdown. The supported syntax is limited Markdown, for example: Hyperkitty's Markdown Syntax ============================ - List items are supported - Even nested ones - Headers with `#` aren't supported, mostly due to their widespread use as comments in code shared on mailing lists. - You can **emphasize** text and _itcalize_ them too - Block code and `inline code` works. - URLs work like they usually do. - Images _do work_, but are disabled by default because of their potential for tracking users. They need to be enabled by administrators through a configuration flag. ``` def sample(): return "yay" ``` While text intentionally written for Markdown rending looks pretty good, plain text sometimes isn't as good. I have applied my branch[1] on both the Mailman installations for these two lists (mail.python.org & lists.mailman3.org). Any feedback or bug reports on weird looking stuff is welcome here or directly [on my PR][1] [1]: https://gitlab.com/mailman/hyperkitty/merge_requests/160 -- thanks, Abhilash Raj (maxking)
