Getting connection refused on postfix trying to connect to mailman-core:lmtp
by Dmitry Makovey Oct. 6, 2017

Oct. 6, 2017

I've got a setup where postfix runs inside one VM(container) and mailman runs inside another one (maxking containers). I've wired everything according to docs yet I'm getting: postfix/lmtp[266]: 66A72800A87: to=<somelist(a)lists.here.stanford.edu>, relay=none, delay=0.5, delays=0.48/0.01/0/0, dsn=4.4.1, status=deferred (connect to mailman-01.stanford.edu[1.2.3.4]:8024: Connection refused) is it something I'm missing on mailman side or postfix side (like this post suggests: https://gitlab.com/mailman/mailman/issues/365 )? Note: I've configured TLS on postfix side but none on mailman side. Is that the issue? -- Sr System and DevOps Engineer SoM IRT

WSGI configuration
by Loring Oct. 5, 2017

Oct. 5, 2017

So I am starting to install mailman3 and following the documentation and am up to the point of configuring the wsgi. The docs give me a config to use (see below) [uwsgi] # Port on which uwsgi will be listening. http-socket = 0.0.0.0:8000 # Move to the directory wher the django files are. chdir = /path-to-django-project-directory/ # Use the wsgi file provided with the django project. wsgi-file = wsgi.py # Setup default number of processes and threads per process. master = true process = 2 threads = 2 # Drop privielges and don't run as root. uid = 1000 gid = 1000 # Setup the django_q related worker processes. attach-daemon = ./manage.py qcluster # Setup the request log. req-logger = file:/path-to-logs/logs/uwsgi.log # Log cron seperately. logger = cron file:/path-to-logs/logs/uwsgi-cron.log log-route = cron uwsgi-cron # Log qcluster commands seperately. logger = qcluster file:/path-to-logs/logs/uwsgi-qcluster.log log-route = qcluster uwsgi-daemons # Last log and it logs the rest of the stuff. logger = file:/path-to-logs/logs/uwsgi-error.log Where does this config go? Does in go in the mailman3.cfg? Any help would be appreciated. -- Richmond Loring rloring(a)bnl.gov Advanced Systems Engineer

Mailman core: basic internationalization howto?
by Thor Atle Rustad Oct. 5, 2017

Oct. 5, 2017

I would like to use Norwegian in the welcome/subscribe/unsubscribe/confirm etc messages from mailman3. For my current project I want all future mailing lists to have Norwegian as default. I find some sporadic info on the subject, but it's fair to say that I would like some simple instructions (e.g. what to copy from where to where, and which configs to change).

Uncaught runner exception: 'str' object has no attribute 'decode'

Oct. 3, 2017

When held mails are released in Mailman (maybe also mails which are not held) they are sometimes not sent nor archived, as mentioned in https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… One of my list admins reported that he released two mails on Sep 25 07:20:48 2017 UTC, and only the first was sent to the members. In the mailman.log I found the following from that particular release: Sep 25 07:20:48 2017 (36) 172.19.199.3 - - "GET /3.0/lists/listname.foo.bar HTTP/1.1" 200 353 Sep 25 07:20:48 2017 (36) held message approved, message-id: <CAF9K74uk331j91PfF6S1nQT2YvxywwhUFBWBBcdMGkNMMU4=TA(a)somemail.com> Sep 25 07:20:48 2017 (36) 172.19.199.3 -

The msgtext argument in 'self._connection.sendmail(envsender, recipients, msgtext)' is supposed to be a string containing only ascii characters.

question about recommended postfix configuration
by Marc Sluiter Oct. 2, 2017

Oct. 2, 2017

Hi, im trying to setup mailman and have an issue: first my environment: - I’m running postfix etc with "mailcow-dockerized": https://mailcow.github.io/mailcow-dockerized-docs/ - I’m running mailman with "docker-mailman": https://asynchronous.in/docker-mailman/ I got almost everything working besides confirm mails (see my other mail), but I had to use another postfix configuration than recommended, I’m wondering why the recommended way didn’t work. Sidenote: I’m not a postfix expert. This is recommended: transport_maps = regexp:/opt/mailman/core/var/data/postfix_lmtp local_recipient_maps = regexp:/opt/mailman/core/var/data/postfix_lmtp relay_domains = regexp:/opt/mailman/core/var/data/postfix_domains This didn’t work, all mails to mailman were rejected. Postfix did not even check the “local_recipient_maps”. After a lot of reading that made sense to me, because when I understand it correctly, “local_recipient_maps” is only checked for domains in “mydestinations”. And there I only have localhost. My first change then was to use “relay_recipient_maps” instead of “local_recipient_maps”, because the domains were also added to the relay configuration "relay_domains". That worked. But then I noticed warnings by postfix about having the same domain in “virtual_mailbox_domains” and “relay_domains”. Made sense again because I used the same domain in my “normal” mail setup (with “virtual_mailbox_domains”) and in mailman. So finally I ended up with adding the mailman files to “virtual_mailbox_domains” and “virtual_mailbox_maps” instead of “relay_domains” and “local_recipient_maps”. Do my findings and changes make sense to you? Or do I miss something important? Good thing is that at least “transport_maps” worked for whatever configuration I used :) Thanks and greetings, Marc

default language ignored
by Marc Sluiter Oct. 2, 2017

Oct. 2, 2017

Hi, one last question for now: how do switch the language of the mails sent by mailman? I have this in my configuration, but without effect: [language.de] charset: iso-8859-1 [language.de] description: German [language.de] enabled: yes [mailman] default_language: de Is it also possible to change the language for a single list? Greetings, Marc

I'm sure this is a small configuration error, but I have followed the instructions for mailman3 and postfix. Basically mailman works fine, but confirmation emails, when answered by the subscriber or would-be subscriber, fails because 'listname' (after the '+something' is stripped off) is not a local user. Also see my post to the postfix group: http://postfix.1071664.n5.nabble.com/address-extension-fails-for-mailman-td…. Mind you, the postfix local_recipient_maps=regexp:/path/postfix_lmtp will correctly match any of the lists, but once the <+something> is added to the listname, it fails. Note that I have configured a subdomain, klubb.domain.com, for my mailing lists. First, my postfix.cf: recipient_delimiter = + smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no append_dot_mydomain = no readme_directory = no smtpd_tls_cert_file=/etc/letsencrypt/live/mailer.example.com/cert.pem smtpd_tls_key_file=/etc/letsencrypt/live/mailer.example.com/privkey.pem smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_helo_restrictions = permit_mynetworks, permit_sasl_authenticated smtpd_sender_restrictions = permit_mynetworks, reject_non_fqdn_sender, reject_unknown_sender_domain smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, smtpd_tls_security_level = may smtp_tls_security_level = may smtp_tls_loglevel = 2 smtpd_tls_loglevel = 2 smtpd_relay_restrictions = permit_mynetworks, permit_sasl_authenticated, defer_unauth_destination mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 172.19.199.0/24 <public.ip>/32 myhostname = mailer.example.com mydomain = example.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = mailer.example.com mydestination = klubb.$mydomain, localhost.$mydomain, localhost, $myhostname, $mydomain relayhost = mailbox_size_limit = 0 inet_interfaces = all inet_protocols = all compatibility_level = 2 transport_maps = regexp:/opt/mailman/core/var/data/postfix_lmtp local_recipient_maps = regexp:/opt/mailman/core/var/data/postfix_lmtp relay_domains = regexp:/opt/mailman/core/var/data/postfix_domains unknown_local_recipient_reject_code = 550 owner_request_special = no propagate_unmatched_extensions = canonical, virtual, alias, forward, include Here is the line in postfix mail.log where the valid listname+token is rejected: NOQUEUE: reject: RCPT from mail-lf0-f43.google.com[209.85.215.43]: 550 5.1.1 <abcliste-confirm+79ecdc9fe57e086b8e1335299ef5255d156b72db(a)klubb.example.com>: Recipient address rejected: User unknown in local recipient table; from=<me(a)mydomain.com> to=<abcliste-confirm+79ecdc9fe57e086b8e1335299ef5255d156b72db(a)klubb.example.com> proto=ESMTP helo=<mail-lf0-f43.google.com> Any help will be appreciated.
