Settings for prevention of spam obfuscation
by Richard Rosner Feb. 26, 2024

Feb. 26, 2024

Are there any settings that may help with making it easier seeing spam as spam? E.g. some mail programs, including Outlook, allow the user to set a from mail address that most mail clients will show instead of the true sender address, but the senders mail address is still present in the sender header field. While some people and companies carelessly abuse that functionality, hiding their true mail address, those bad practices also are abused my spammers and others. Does mailman have any settings that would remove any such obfuscations, e.g. in this case detect the manipulated from address and replace it with the sender address? While I do run my own spam filter, it's virtually getting harder every day to make sure you detect all spam while not having too many false positives. If it was possible to reverse at least the most obvious manipulations, that would probably already help. Also, it would make it much easier for the users to see at first glance who actually wrote an email. It's always less trustworthy if the senders address is shown as user3168(a)suspiciousdomain.gg instead of it being manipulated to say support(a)yourprovider.com.

Unable to get Postfix to bounce messages to non-existent lists
by skenny＠scss.tcd.ie Feb. 21, 2024

Feb. 21, 2024

We have Mailman working well in our environment, but there's one thing I can't seem to make happen no matter what I try. The situation is as follows: Postfix runs on on a different server than Mailman. Its main.cf says local_recipient_maps = $alias_maps transport_maps = regexp:/var/mailman-data/postfix_lmtp relay_domains = regexp:/var/mailman-data/postfix_domains The file postfix_lmtp is initially generated by Mailman (running on a different machine). A background process creates a version of the file wherein the lmtp IP address is changed to the network IP of the Mailman server, and that version is sync'd over to the Postfix server. On the latter, a typical block for a list then reads as follows (where A.B.C.D is the IP address of the Mailman server): /^some-list(a)lists\.scss\.tcd\.ie$/ lmtp:[A.B.C.D]:8024 /^some-list-bounces(\+.*)?(a)lists\.scss\.tcd\.ie$/ lmtp:[A.B.C.D]:8024 /^some-list-confirm(\+.*)?(a)lists\.scss\.tcd\.ie$/ lmtp:[A.B.C.D]:8024 /^some-list-join(a)lists\.scss\.tcd\.ie$/ lmtp:[A.B.C.D]:8024 /^some-list-leave(a)lists\.scss\.tcd\.ie$/ lmtp:[A.B.C.D]:8024 /^some-list-owner(a)lists\.scss\.tcd\.ie$/ lmtp:[A.B.C.D]:8024 /^some-list-request(a)lists\.scss\.tcd\.ie$/ lmtp:[A.B.C.D]:8024 /^some-list-subscribe(a)lists\.scss\.tcd\.ie$/ lmtp:[A.B.C.D]:8024 /^some-list-unsubscribe(a)lists\.scss\.tcd\.ie$/ lmtp:[A.B.C.D]:8024 The only problem with this is that if someone sends a message to a non-existent mailing list, Postfix nevertheless accepts the mail, and it loiters in the queue for several days before eventually being bounced back to the sender. I want to get Postfix to reject mail to non-existent mailing lists immediately. I've come up short with each variation of main.cf settings I've tried, and would greatly appreciate any advice. Many thanks Stephen Kenny

Hi there, I am running mailman3 on Debian 12 - latest package (GNU Mailman 3.3.8 (Tom Sawyer)).

by Zaheer Abbas Feb. 9, 2024

Feb. 9, 2024

I have a situation where I need to add / remove 10-20 non-members to a particular list every week and set the moderation bit to 'accept immediately (bypass other rules). I do the above via postorius because I couldn't find a way to do this via mailman shell. Can anyone help me please to achieve the above? I know how to remove all non-members via /opt/mailman/mm/bin/mailman shell -l list.example.com for nonmember in m.nonmembers.members: ... nonmember.unsubscribe() ... commit() I am just having difficulties adding the non-members and setting the moderation bit to 'Accept' Currently I am using Mailman 3.2.2 (La Villa Strangiato) and Postorius Version 1.2.4 so cant use 'postorius => settings -> message acceptance -> id_accept_these_nonmembers' -- Regards, Zaheer

Problems with mailman core translation and other details
by celi＠dieese.org.br Feb. 9, 2024

Feb. 9, 2024

Hi. We did a fresh install of the Debian Mailman 3 full package. I'd like all components to be translated into pt_BR. I downloaded the latest updated translations from weblate, which says that 100% of the project (all components) are translated. I checked and recompiled mailman.po with msgfmt without errors. I followed all instructions I saw, included the ones from the topic How to change the language in mailman3 in this list. Everything almost OK, except from the fact that none of mailman's core email messages are being translated, even though mailman.po shows the right messages. Also, strange things happen to these .po files. The web interface is almost perfect, but some messages (just some) are not correct - although the corresponding django.po appears to be OK. It´s the case below: the pair msgid/msgstr seems to be OK, but this particular sentence is not being translated. #: templates/postorius/lists/summary.html:88 #, python-format msgid "" "\n" " To subscribe you can send an email with 'subscribe' in the " "subject to\n" " <a href=\"mailto:%(address)s?subject=Subscribe\">" "%(address)s</a>\n" " or use the form below:\n" " " msgstr "" "\n" " Para se inscrever você pode enviar um e-mail com o assunto " "'subscribe' para\n" " <a href=\"mailto:%(address)s?subject=Subscribe\">" "%(address)s</a>\n" " ou use o formulário abaixo:\n" What am I doing wrong? Or what can I do to make things suitable? Additional info: GNU Mailman 3.3.3 (Tom Sawyer) Python 3.9.2 (default, Feb 28 2021, 17:03:44) [GCC 10.2.1 20210110] Postorius v. 1.3.4 HyperKitty v. 1.3.4 Thanx for any help

Hiding an ML from a site
by Odhiambo Washington Feb. 8, 2024

Feb. 8, 2024

I host two MLs on the same server/same MM3 instance. Under the Django Admin interface, I created two sites. I expected that each ML will belong to its own site and should not be visible on another site. On https://mm3-lists.kictanet.or.ke/mm/lists/, you can see the two lists. How do I stop the "Users" list from showing up on this site ( https://mm3-lists.kictanet.or.ke/mm/lists/) since it belongs to its own site - https://exim4u.org/mm/lists/ ? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 In an Internet failure case, the #1 suspect is a constant: DNS. "Oh, the cruft.", egrep -v '^$|^.*#' ¯\_(ツ)_/¯ :-) [How to ask smart questions: http://www.catb.org/~esr/faqs/smart-questions.html]

search this list searches more then just this list
by Marco van Tol Feb. 6, 2024

Feb. 6, 2024

Hi there, We run the following versions: mailman-core: 3.3.9 mailman-core-api: 3.1 mailman-core-python: 3.11.6 hyperkitty: 1.3.8 We have several lists on our server, I will write down a list of example list names that are good enough for the purpose of my question. xx(a)domain.tld <mailto:xx@domain.tld> yy-xx(a)domain.tld <mailto:yy-xx@domain.tld> zz-xx(a)domain.tld <mailto:zz-xx@domain.tld> When I now visit the archives for xx(a)domain.tld <mailto:xx@domain.tld> and enter a search phrase in “search this list”, the results include the other 2 lists. It looks like “search this list” searches for keyword in any listname that matches the one from "this list". Is there a way to really only search “this list” when I go to the archives for xx(a)domain.tld <mailto:xx@domain.tld>? I have tried to change the url for the results to have a ‘^’ in front of the listname, but that gives an error :-) Thanks in advance! Marco van Tol

Disable all mail capabilities
by Hope Less Feb. 2, 2024

Feb. 2, 2024

I have a decades old list that was abandoned on my server. I upgraded it to mailman3 but it never came back to life. It is causing me some grief. I want to keep the archives up but totally disable any mail capabilities. I have turned off mail for the domain but I still get 'crap' that tries to relay. I've manually tried to remove stuff from the transport tables in Postfix but I still get mail. I'm not sure where the problem lies. If I can't stop this I'll have to remove the list entirely which includes the archives. I really wish to leave the archives up. Any idea on how I can remove the mail capabilities and leave the rest? Thank You.

after upgrade: OperationalError: no such column: hyperkitty_mailinglist.archive_rendering_mode
by Hans Mayer Jan. 31, 2024

Jan. 31, 2024

Dear All, recently I did a system os upgrade debian 11.8 -> 12.4 / bullseye -> bookworm This did also upgrade Mailman3 version 3.3.3 -> 3.3.8 as a used the packages which came with Debian OS. Initially after the upgrade I had some troubles with the MM3 services to start, but I fixed this. Now almost everything is running. Only the Archives are not working. The browser shows a server error, when I look at the mailman-web.log I see ERROR 2024-01-31 15:14:14,403 2699563 django.request Internal Server Error: /mailman3/hyperkitty/ Traceback (most recent call last): File "/usr/lib/python3/dist-packages/django/db/backends/utils.py", line 84, in _execute return self.cursor.execute(sql, params) File "/usr/lib/python3/dist-packages/django/db/backends/sqlite3/base.py", line 423, in execute return Database.Cursor.execute(self, query, params) sqlite3.OperationalError: no such column: hyperkitty_mailinglist.archive_rendering_mode When I check the schema I find such a column in table "mailinglist" I assume there is only one solution, to uninstall and delete everything and start from scratch. Or is there a way the check all tables with a script and do an table update for missing columns ? Or a partial installation of hyperkitty, as I don't care about the archives. I am using sqlite3 as DB backend. Kind regards Hans --
