migrations questions
by Jeffrey Westgate 09 Feb '23

09 Feb '23

Greetings all - My current build is running Mailman version: 2.1.20, on a long-in-the-tooth Scientific Linux release 7.9 (Nitrogen), with sendmail I'd like to go RHEL9, and Mailman 3.3.8 (Tom Sawyer), with postfix, on a new parallel VM - plan is to build a parallel server, same hostname, different IP, migrate all data/archives and billing info (we have that scripted), then do a dns change to point to the new IP after testing. Are there any means of scripted migration from old to new? Can I go from 2.1.20 direct to 3.3.8 - or do I need to go to 2.1.39 as an intermediate first? It's a service we provide, and we like to keep the our level of interaction to a minimum, so 2.1.20 was the first built "I" did back when RHEL7/SL7 was in it's early days. Going latest would fill that mold for us for a while. I'm currently looking at the wiki.list.org, but am having troubles locating Mailman3. version Site Admin doc - they seem to be v2.1 - I could be missing them.

New Installation of MM3 is not archiving
by Onyeibo Oku 30 Jan '23

30 Jan '23

Greetings, I finally completed installation of Mailman 3 following the instructions here: https://docs.mailman3.org/en/latest/install/virtualenv.html#initial-configu… I got a lot of support from this mailing-list too and I am mighty grateful for that. My new MM3 instance does not seem to be archiving. List subscribers are currently sending and receiving mails on their subscribed lists. However, none of the correspondence is showing up at https://mailing-list-site.tld/archives/. That page shows a listing of the active mailing-lists with '0 participants' and '0 discussions'. Whereas, those lists contain mails. How do I troubleshoot this?

Question: If the list name and a member address are known, can foreign mails be channeled into the list?
by Thomas F. Holz 25 Jan '23

25 Jan '23

Hello to the round. Unfortunately I could not find a better place for my questions, nor did I find any answers within the docs or by Google. So here it is. The questions refer to Mailman 2.1.23. If I know the address of a list member and the address of the mailing list, I seem to be allowed to write in the list in his place. Is this correct? It seems to me that this is possible in at least two ways with the lists I am responsible for, and I don't like that: 1)--- First, I can fake the sender address. If the original sender address and mail with the forgery are sent from the same domain, then this is not prevented by the MTA (SPF/DKIM check), is it? With freemailers like gmail, web.de, gmx etc. this doesn't seem so impossible to me (i.e. that listmember and bad guy write from the same domain). 2)--- Second, even more strange to me: If I write to the mailing list from a valid address (which is NOT a member of the mailing list), and specify a "return-to" in the header with a listmember's address, then that gets waved through to my mailing list as well. My mailman lists here seem to ignore the "From" address completely then. In this case, it doesn't even matter which domain the bad guy writes from, as long as the return address stands up to the usual checks (SPF/DKIM/DMARC). Have I understood this correctly? And if this is as described, how can I prevent this? Background: I have inherited a larger Sendmail server and several dozen Mailman lists. Unfortunately, migration to Mailman3 is not an option (at least in the foreseeable future). So I have to live with the given - and annoy others with stupid questions from time to time. Sorry for that. In advance with thanks and greetings from Germany, Thomas

Question
by Papa ONYXMA 23 Jan '23

23 Jan '23

Couple of questions. 1. Should we be sending to everyone using blast(a)onyxma.com or blast(a)lists.onyxma.com 2. When a person sends, even though they are in the "list", they do not get a copy in their inbox. Is there a setting we can change so the sender gets a copy too if they are in the full list? I know they have what is in the sent box, but we'd like a sender to get a copy as well in their inbox since they are on the list. 3. Occasionally when we send to the blast everyone does not get the notice. It's rare that it happens, but it does. When it happens only a handful of people don't get it (not in their spam/junk either). Advice? *Papa "Pap" ONYX (Marcus Allen)* ONYX Mid-Atlantic ONYX National Council Member papa.onyxma(a)gmail.com <funkdog3660(a)gmail.com> 571-215-4683 cell

Constant Mailman error messages
by PCZero Support 05 Jan '23

05 Jan '23

I have a hosting client using MailMan with about 10,000 subscribers. He sends mail only about once or twice a year and it is an announcement only list, no discussion, he is the only one who posts. Recently he posted and now I am getting constantly flooded with the following message. I have killed the mailman running processes and rebooted the server. The error message continue. What is causing this error and how do I stop it? >Delivered-To: support(a)pczero.net >Envelope-to: root(a)morpheus.rvaservers.com >To: root(a)morpheus.rvaservers.com >Subject: lfd on morpheus.rvaservers.com: Excessive resource usage: >mailman (11571 (Parent PID:11569)) >From: <root(a)morpheus.rvaservers.com> >Date: Thu, 22 Dec 2022 08:35:47 -0500 > >Time: Thu Dec 22 08:35:47 2022 -0500 >Account: mailman >Resource: Process Time >Exceeded: 1857 > 1800 (seconds) >Executable: /usr/bin/python2.7 >Command Line: /usr/bin/python2 >/usr/local/cpanel/3rdparty/mailman/bin/qrunner --runner=BounceRunner:0:1 -s >PID: 11571 (Parent PID:11569) >Killed: No

Changing "From:" in header..
by Robert Wertheimer 03 Jan '23

03 Jan '23

I'm managing 2 mail lists using MM 2.1.38 in cpanel. I set up a list last year and another list in the last couple months. As far as I can tell, both lists have the same options set in general. However, the new list has a very nice "From:" header format showing the full name of the person who posted, "Via", and the name of the list. The older list always just says the name of the list in the "From:" header. Can't seem to find a way to change this behavior to match the first list. I've looked through the help files and Wiki and have come up empty. Thanks for your time. Robert Wertheimer
