I would like to install mailman3 on my debian box (bookworm), but use an already existing postfix mail server on another host (can that be done?). I have the following settings in the mailman.cfg file in /etc/mailman3 [mta] # The class defining the interface to the incoming mail transport agent. #incoming: mailman.mta.exim4.LMTP incoming: mailman.mta.postfix.LMTP # The callable implementing delivery to the outgoing mail transport agent. # This must accept three arguments, the mailing list, the message, and the # message metadata dictionary. outgoing: mailman.mta.deliver.deliver # How to connect to the outgoing MTA. If smtp_user and smtp_pass is given, # then Mailman will attempt to log into the MTA when making a new connection. smtp_host: localhost smtp_port: 25 smtp_user: smtp_pass: # Where the LMTP server listens for connections. Use 127.0.0.1 instead of # localhost for Postfix integration, because Postfix only consults DNS # (e.g. not /etc/hosts). lmtp_host: 127.0.0.1 lmtp_port: 8024 I have SSH tunnels in place which make port 25 on the remote mail server available from my mailman server and port 8024 on my mailman server available on port 8024 on the remote mail server (if that's what's do be done - for the 2nd part, the port 8024, I am not fully sure if my understanding is correct). For some reasons, when starting mailman3, it tries to execute postmap which is installed on the mail server, but not on the mailman server. I guess, that this occurs because of the config file settings for incoming: and outgoing:. How can I change my configuration to get this setup working? Or (if this is not possible): How should I configure my system to have a new system running mailman3 connect to an already existing server running postfix. (What I probably should mention: The mailing lists should be for the mail domain which the existing postfix mail server is responsible for.)

I have an Ubuntu server with Postfix and the Mailman list manager. My server stopped working, so I need to find a way to list the emails registered on the list of the Mailman. Note: I was able to mount the data partition, so I have all the files.

The [Mailman3 web installation instructions](https://docs.mailman3.org/en/latest/config-web.html#scheduled-tasks-required) ask for the configuration of various cron jobs. This is not specified in the [Debian Mailman3 installation instructions](https://salsa.debian.org/mailman-team/mailman-suite/-/blob/master/debian/README.Debian) , which might suggest that the Debian mailman3-full package sets up what is required. Yet no cron jobs are listed in /var/spool/cron/crontabs/. In addition, trying to run the specified jobs from the command line (e.g. sudo -u list mailman /usr/bin/mailman-web runjobs hourly) results in the error: ValueError: Language code already registered: ar.

I've installed GNU Mailman 3 on Debian 11 using apt install mailman3-full. I'm now trying to set up the web UI for it, as list admins will not want to use the command line to manage lists. The Mailman docs say to consult the Postorius docs. The Postorius docs seem to cover initial Postorius configuration up to creating a Django site, but give no details on how this integrates with Mailman 3 — and surely the mailman3-full package, which includes mailman3-web, should already have done this? The page at https://packages.debian.org/buster/mailman3-web implies that the web UI is visible at http://«host»/mailman3 , but it is not. It *does* say it's optional, but I can't find any information on how to configure this. lsof -nP -iTCP -sTCP:LISTEN shows ports 8001 and 8024 are listening:

python3 20949        list   23u  IPv4  97450      0t0  TCP 127.0.0.1:8024 (LISTEN)
python3 20953        list   24u  IPv4  97452      0t0  TCP 127.0.0.1:8001 (LISTEN)
python3 20963        list   24u  IPv4  97452      0t0  TCP 127.0.0.1:8001 (LISTEN)
python3 20964        list   24u  IPv4  97452      0t0  TCP 127.0.0.1:8001 (LISTEN)

but 8001 returns JSON and 8024 is Mailman's internal LMTP port. There doesn't seem to be *any* web UI exposed. I'm not a Python developer, and know little of uWSGI, which is mentioned on the page. The uWSGI documentation is massive, and doesn't really have any sections which look like they might be helpful. I can't find any instructions on how to configure the mailman3-full package so there's a working web UI — everything seems to be based around installing mailman3 from scratch, and assumes a good level of Python knowledge to boot. Please could somebody tell me how to get the web UI working? (Or, failing that, point me to a mailing list package that works similarly and isn't Mailman?)

I'm trying to backport mailman3-full from Debian Bullseye to Debian Buster. I've followed the official guide , but when executing sudo mk-build-deps --install --remove I get an error:

Removing mailman3-build-deps:amd64 because I can't find python3-importlib-resources:amd64

I've researched that package, and apparently it's only found on Bullseye (testing), so I can't just install it. How should I proceed to backport mailman3-full? Maybe I also have to backport python3-importlib-resources? I've also tried adding testing repositories and just installing mailman3-full from there, but then it wants to upgrade a lot of packages to the testing version, which I'm not comfortable with.

Running Ubuntu 16.04, mailman 2.1.24, postfix 3.1.0. The server runs several domains. Postfix and virtual mailboxes are running well. After much wrestling I have mailman working with one list. I then imported a list, from the previous host, and used withlist to import it. I checked that the aliases were generated, reloaded postfix, and sent a test message, which generated an unknown user bounce. This lead me to check by creating a new list and testing it. Same message. The list address is translated to an @localhost, which I understand is normal, and the generated aliases include @localhost. I'm not really sure how to move forward. Any thoughts?

Suppose I run the command: sudo ./list_members Physicians And I want to prefix the output like this: Physicians user@domain.com Physicians user2@domain.com Physicians user3@domain.com Physicians user4@domain.com Is it possible for me to prefix StdOutput like that?

I am working on Mailman version 2.1.12-14.el6.x86_64 and sendmail that came inbuilt with RHEL 6.0. My mailman does not directly send mails to the destined domains. It relays to another appliance called "Ironport" and that in turn verifies various parameters like spam, virus and so and then sends to the destined domains. But, I recently observed an issue on this setup after lot many years of usage, suddenly from few days, the maximum no of users from one of the mailing lists got auto-unsubscribed with reason "BY BOUNCE". I tried searching in mailman logs and many websites for the solution but nothing helped. The only thing I could get from previous "subscribe" log is : /var/log/mailman/subscribe-20181028:Oct 27 09:01:05 2018 (17828) : deleted ; disabled address /var/log/mailman/subscribe-20181028:Oct 27 09:01:05 2018 (17828) : auto-unsubscribed [reason: BYBOUNCE] The above message is an example. Almost 142 mail ids got deleted with the above reason. My query here is, if mailman is not sending directly the mails to the users, what is causing mailman to bounce back to the sender that leads to the auto-unsubscribe from the list.

I have set up postfix with spamassassin, and then added mailman for mailing list management, everything on Debian 9 Stretch: postfix: 3.1.8 mailman: 2.1.13 spamassassin: 3.4.1 The problem is that the mail that is reinjected by MailMan is re-checked by SpamAssassin for each single recipient of mailing lists, which puts quite some burden on the system. Since the mail is already checked when originally accepted, I would like to circumvent the second spam check. The configuration is as follows: Mailman has MTA='Postfix' in the mm_cfg.py file. Postfix ======== main.cf ------- virtual_alias_maps = hash:/etc/postfix/virtual, hash:/var/lib/mailman/data/virtual-mailman master.cf ---------- smtp inet n - y - - smtpd .... -o content_filter=spamassassin smtps inet n - y - - smtpd .... -o content_filter=spamassassin submission inet n - y - - smtpd ... -o content_filter=spamassassin -o receive_override_options=no_milters ... spamassassin unix - n n - - pipe user=debian-spamd argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f ${sender} ${recipient} What would be a possible way to make SpamAssassin skip the check on email delivered from MailMan?

I am writing for some help regarding Postfix configuration. I cannot seem to get Postfix configured properly to transfer mail to the mailing list installed on the same server. I followed many steps over the last few days, and the last one I followed is at http://www.postfix.org/VIRTUAL_README.html under the section Mailing Lists. Can someone please look at this and let me know what I am missing? Basically, Postfix has been configured for base email to be sent to xxx@mail-test.company.org and I would like the mail list to use xxx@listtest.company.org. **DYN-DNS** listtest.company.org A 216.111.222.85 listtest.company.org MX 216.111.222.85 listtest.company.org TXT "v=spf1 a ptr mx ip4:216.111.222.85 mx:mail-test.company.org -all" mail-test.company.org A 216.111.222.85 mail-test.company.org MX 216.111.222.85 mail-test.company.org TXT "v=spf1 a ptr mx ip4:216.111.222.85 mx:mail-test.company.org -all" **main.cf** myhostname = mail-test.company.org mydomain = company.org myorigin = $hostname alias_maps = hash:/etc/aliases, hash:/etc/mailman/aliases alias_database = hash:/etc/aliases, hash:/etc/mailman/aliases recipient_delimiter = + virtual_alias_maps = hash:/etc/postfix/virtual mydestination = $myhostname, listtest.$mydomain /etc/postfix/virtual: listname-request@listtest.company.org listname-request listname@listtest.company.org listname owner-listname@listtest.company.org owner-listname /etc/aliases: listname: "/usr/lib/mailman/mail/mailman post mailman" owner-listname: ... listname-request: ... **mm_cfg.py** DEFAULT_URL_HOST = 'listtest.company.org' DEFAULT_EMAIL_HOST = 'listtest.company.org' add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST) MTA = 'Postfix' The first part of the log shows the rejection of listtest.company.org -- whereas the second part shows successful transfer to mail-test.company.org **/var/log/maillog** Aug 17 15:46:50 listserv postfix/smtpd: NOQUEUE: reject: RCPT from Mail1.company.org[66.173.196.101]: 554 5.7.1 : Relay access denied; from= to= proto=SMTP helo= Aug 17 15:46:50 listserv postfix/cleanup: D3F93209F1: message- id= Aug 17 15:46:50 listserv postfix/smtpd: disconnect from Mail1.company.org[66.173.196.101] Aug 17 15:46:50 listserv postfix/qmgr: D3F93209F1: from=, size=6670, nrcpt=1 (queue active) Aug 17 15:46:50 listserv postfix/cleanup: F37B120A3B: message- id= Aug 17 15:46:51 listserv postfix/qmgr: F37B120A3B: from=, size=6819, nrcpt=1 (queue active) Aug 17 15:46:51 listserv postfix/local: D3F93209F1: to=, relay=local, delay=0.18, delays=0.17/0.01/0/0, dsn=2.0.0, status=sent (forwarded as F37B120A3B) Aug 17 15:46:51 app02-listserv postfix/qmgr: D3F93209F1: removed Any help would be greatly appreciated.

after installing mailman on debian wheezy and running newlist mailman i get the Error: IOError: [Errno 2] No template file found: 'emptyarchive.html'

I'm maintaining a server which runs mailman. In it I find a crontab which looks like the following: 0 8 * * * list [ -x /usr/lib/mailman/cron/checkdbs ] && /usr/lib/mailman/cron/checkdbs 0 9 * * * list [ -x /usr/lib/mailman/cron/disabled ] && /usr/lib/mailman/cron/disabled ... When I type *list* I get > No command 'list' found .. My searches for "crontab list", "linux list command", "mailman cron list" bring up results for listing things. What does list in crontab do ? What command is list refering to ?

I try to select the option but it doesn't work. Which key(s) do I use to enter it?

I am working on an install of mailman 3.0.3 on Ubuntu Server 16.04 which ships with Python 3.5.1 and 2.7.11. Per Barry Warsaw that version of mailman requires Python 3.4.n. https://gitlab.com/mailman/mailman/issues/184 My choices seem to be: downgrade 3.5.1 install 3.4.4 in parallel use conda to create a virtual environment another approach??? What would be the best way to accomplish this?

I'd like the footer of a Mailman list to include an image. Is this possible? If yes, how? I tried the obvious path of just typing , but that didn't work.
