I am trying to install Mailman 3 from source using: https://docs.mailman3.org/en/latest/index.html My first question is where is the best place to get assistance or ask questions regarding the installation process? I am not sure if mailman-users is that place anymore. Thanks, Brian

Re: [Mailman-Users] Mailman 3 Ready?

It's email, there are no guarantees. I hate to say that, but that's the way it is. In particular, I'm concerned about the "iRedMail" integration, which may be a complete wildcard from my point of view. With respect to the relevant iRedMail components, I can say that Mailman 3 is perfectly happy with Postfix as MTA (it's the recommended configuration, although I use Exim4 for historical reasons), and I've been satisfied with a small-scale set of lists (about 10 active ones, with at most 20 subscribers total) using Apache+mod_swgi to host Postorius and HyperKitty. The problem would be if your friend (is that the Frank in the CC? hi, Frank!) really really wants to manage Mailman 3 through iRedAdmin -- that will get messy I suspect, and pragmatically speaking, we can't support it, we don't have the cycles. So he'd be on his own, especially since the iRedMail folks have their own bespoke mailing list manager. I would recommend avoiding iRedAdmin integration, and just using Postorius since the subscribers and non-site-admin moderators (if any) will need to use Postorius anyway. Ignoring the iRedAdmin issue, the absolute simplest is 1. Install any Linux distribution with a Docker package. 2. Install the distribution's Docker package. 3. Download and install Mailman Project's Mailman 3 container. 4. Upgrade the container manually (ie, download and reinstall) as appropriate. For reference, what I would recommend to my friends, who would give me hands-on access in emergencies: 1. Install the Debian distribution. (What I use.) 2. Pin the Mailman 3 packages to "experimental". The idea would be to get Mailman 3 upgrades as fast as possible, even at the risk of packaging issues. (My experience with default-to-experimental system for several years was that this happened at most once a year, and the three or four cases all got fixed within days.) 3. Install the Mailman 3 packages. 4. Adjust any dependencies that need non-"stable" versions. 5. Upgrade via apt or whatever occasionally. 6. When Mailman 3 is working well, downgrade the pins to a more stable level. Since you do have such a friend, there's probably a similar process that works for his distribution-of-choice. > The problem is that my MacOS users are getting tripped up by the > mangling, as it is hidden by the mail clients.

I guess we could provide a setting where reply-to goes *only* to author, instead of to author *and* list as we currently recommend. But that is going to make you (or list owners) the focus of user ire because their intended replies to list go only to author. What do you think? tl;dr The rest is me blowing off steam. :-) > The fact that the mangling will continue is a disappointment. It's a disappointment to the sane people at the IETF, too, including the rep from Yahoo!, who's a very smart lady (I may be biased, she gave me a kitten once. ;-) Yahoo! is violating the original concept (DMARC "p=reject" was supposed to be used *only* for "transactional" mail, i.e., direct private communication between a business and its clients), but I see her point: when you've had a hundred million or so address books hacked and sold to spammers, and the spammers are sending literally millions of "recommendation from a friend" spams per hour for days on end, you use the tools to hand. > I’m inclined to tell all my AOL and Yahoo users and others in the same > boat to find another email service. I know the feeling. I'm lucky in that respect: the Ministry of Education prohibits use of yahoo mailboxes at Japanese universities. (Which is a WTF of a different kind: yahoo.co.jp is a franchise, not controlled by yahoo.com, and doesn't use p=reject at least at the time MoE issued that policy.) Mail is just hard. It was designed for a "friendly network of users", not for today's rather hostile open Internet, and even if they had envisioned this in the 70s when the message format and SMTP mail transmission protocol were designed, the fundamental problem is that pretty much everyone has a genuine need, even if only occasional, to receive messages from untrusted and even unknown senders.

Setting up From: field as list address
by Steven Maddox Nov. 25, 2019

Nov. 25, 2019

Hi folks, I'm trying to configure our mailman3 lists (via postorious) in a way that'll mean they'll behave in the way way that I've witnessed on another 3rd party list (one running mailman2). This is where (when receiving a message from the list) the From: is the list itself, and the person who actually sent it bizarrely appears as a CC:, for example... From: Steven Madox via Shropshire LUG <shropshire(a)mailman.lug.org.uk> Subject: [Shropshire LUG] Whatever To: shropshire(a)mailman.lug.org.uk CC: s.maddox(a)lantizia.me.uk At the moment our settings are the default/recommended... I *was* just going to set munging to 'Reply goes to list' which would just set a 'Reply-To' header... until I realised that... a) that won't help Thunderbird users as it just ignores Reply-To if it came from a list b) doesn't fix the issue with people having their own SPF/DKIM set on their mail domains So ultimately I'm starting to see why this 3rd party mailing list (another linux user group, a neighbouring one just south of us) does it this way... if anyone knows the mailman3 equivalent setting? p.s. I've read both the mailman2 and 3 notes related to why munging is not recommended, but I'd still like to know how this is done - to keep our options open more than anything. -- Steven Maddox Lantizia

[Mailman-Users] Mailman 3 Ready?

We have ARC support in Mailman 3, but (a) like most envelope manipulation, that should be done in boundary MTAs, not in Mailman, and (b) ARC implementation is not universal. *Very likely* some of your subscribers are going to lose mail if you depend on ARC, rather than munge from. > I need to get this done before they start on my already thinning > hair! I sympathize. I tell the little kids I meet that my hair grows out of the bottom of my face, not the top (it's very alliterative in Japanese[1], the kids frequently don't get it but the accompanying adults usually laugh). > I’m ready and eager to move on to MM3 on a Linux box. The obvious "turn-key" installation is to use the Docker containers, which Abhilash keeps fairly up-to-date. But see comment below about universal working solutions. Which distro do you have?

If your friend is the type to get his hands dirty with code, and has the time for development activity, mailman-developers(a)python.org would also be useful. You might be better off getting bids from consultants. There's a page listing them on wiki.list.org. > I have looked for both free and commercial alternatives to MM, There are sites that support MM commercially. I think the prices are reasonable, of course YMMV on that. Again, there's a page for those services on wiki.list.org.

Adding / manipulating users
by Seth Seeger Nov. 19, 2019

Nov. 19, 2019

Hello, Thank you for your help with the moderation status. My next question - I have two lists from Yahoo to import. I’ve migrated them through groups.io and have a convenient export. I now have all the data in formats I can handle. (json file for members, mbox for archives.) What’s the best way to import hundreds of users, setting their mail delivery status and moderation status at the same time? (There doesn’t seem to be a command line option for adding members anymore where you can also set their delivery status.) I’ve looked at the documentation, but couldn’t figure out what to do. Thanks, Seth

postorius ssl-certificates for virtual hosts

Nov. 18, 2019

Hello, On my server are several virtual hosts running with different lists per host. The appropriate webaddress is in general: https://lists.[domain]/mailman3/postorius/lists/[listname].lists.[domain]. My domains: [domain-1] starts with a b* [domain-2] starts with a s* [domain-3] starts with a t* If I use the webadress https://lists.[domain-1]/mailman3/postorius/lists/[listname].lists.[domain-… and I do a click on the https-symbol in the address line of my browser I get the secury-information " every thing is ok" and the certificate-information is about the wildcard-certificate I just created for the right domain. Different result is for the webadress https://lists.[domain-2]/mailman3/postorius/lists/[listname].lists.[domain-…. In this case I get an information like "you are using a wrong certificate" clicking on the https-symbol references tot he certificate of [domain-1] I set in my apache2 configuration a symbolic link to apache.conf in the /etc/mailman3/directory and made this active. What did I wrong?? If I set use_https to yes in mailman.cfg I get on the website for all lists: postorius: Something went wrong Mailman REST API not available. Please start Mailman core. In the logs I found … mailman.log Nov 14 23:04:25 2019 (28584) command runner started.
