where to configure max_days_to_hold on MM3 GUI interface?
by Shashikanth Komandoor Feb. 6, 2020

Feb. 6, 2020

Hi Sir, I came to know that the held messages can be restricted to be processed after a specific no of days or can be discard after some days using the parameter *max_days_to_hold*. But I could see that parameter value configurable on MM2 GUI interface in General Options but I don't see the same on the MM3 GUI interface. Could you please help me if I am missing something? -- Thanks & Regards, Shashi Kanth.K 9052671936

by Dieter Leupold Feb. 6, 2020

Feb. 6, 2020

Hi all, a short question (MM3.1.1): is it possible to avoid responses when someone sends emails to the request-address (xxx-request(a)lists.xxxx.com) of a mailinglist? Thanks for your information! Dieter Leupold

Deliverability and Spam Filtering
by tom＠gather.coop Jan. 30, 2020

Jan. 30, 2020

Hi folks! First time poster, long time Mailman user. I am setting up a new Mailman 3 instance, and am super excited about the REST API. I plan to use it to enable tight integration with a separate web app that I maintain. As I am setting up the mail server, I am wondering about two related things: deliverability (for outgoing mail) and spam filtering (for incoming mail). What solutions have folks used for these? I know it is generally common now to outsource this critical task to a cloud provider like Mailgun or etc. Have folks needed this or is running ones own incoming and outgoing mail not a big deal? So many horror stories out there... As far as Mailgun goes, I think it should be straightforward to configure it for outgoing mail, but I'm not sure how I'd use it for incoming. Mailgun can forward mail via HTTP or to another email address. Neither I think would work out of the box. It would be great if there were a REST API endpoint for incoming mail, but I don't think such a thing exists, right? Perhaps I could add one? Another thought I had was that I could write a simple HTTP server that receives mail from Mailgun and forwards it to Mailman via LMTP. But it seems simpler to go right to Mailman's core API given that one exist already. Or am I thinking about this all wrong? Are there other more suitable services out there? I looked for cloud MTA providers but didn't turn up much except for in the large enterprise space, which I'm sure I can't afford. Thanks for any thoughts!

SUBSCRIBE_FORM_SECRET in MM3?
by Gila Halpern Jan. 30, 2020

Jan. 30, 2020

I've been looking into ways to prevent spam on my company's list, and one thing I came across was the SUBSCRIBE_FORM_SECRET option in the Mailman configuration, which embeds a CSRF token into the form, and prevents it from being submitted until five seconds after it renders, to keep bots from subscribing. Unfortunately, the information I found pertained to Mailman 2. Does this option exist in MM3 as well, or is there a similar option?

Mass subscribe gives HTTP Error 500 when using custom template
by Jeffrey D Jan. 30, 2020

Jan. 30, 2020

Hi, I have some issues with the Mass Subscribe option on Mailman 3.2.1. When using a custom "The notice sent to a member when they are subscribed to the mailing list." template, Postorius will throw an exception after pushing the "Subscribe Users" button on Mass Subscribe. In the web interface you will see a red notification bar with the text: "HTTP Error 500: b'A server error occurred. Please contact the administrator.'". And in the Mailman.log you will see the following error message: Traceback (most recent call last): File "/usr/lib/python3.7/wsgiref/handlers.py", line 137, in run self.result = application(self.environ, self.start_response) File "/usr/lib/python3/dist-packages/mailman/database/transaction.py", line 50, in wrapper rtn = function(*args, **kws) File "/usr/lib/python3/dist-packages/mailman/rest/wsgiapp.py", line 216, in __call__ return super().__call__(environ, start_response) File "falcon/api.py", line 215, in falcon.api.API.__call__ File "falcon/api.py", line 189, in falcon.api.API.__call__ File "/usr/lib/python3/dist-packages/mailman/rest/members.py", line 266, in on_post pre_approved=pre_approved) File "/usr/lib/python3/dist-packages/mailman/app/subscriptions.py", line 520, in register list(workflow) File "/usr/lib/python3/dist-packages/mailman/app/workflow.py", line 69, in __next__ return step() File "/usr/lib/python3/dist-packages/mailman/app/subscriptions.py", line 326, in _step_do_subscription self.member = self.mlist.subscribe(self.subscriber) File "/usr/lib/python3/dist-packages/mailman/database/transaction.py", line 85, in wrapper return function(args[0], config.db.store, *args[1:], **kws) File "/usr/lib/python3/dist-packages/mailman/model/mailinglist.py", line 494, in subscribe notify(SubscriptionEvent(self, member)) File "/usr/lib/python3/dist-packages/zope/event/__init__.py", line 31, in notify subscriber(event) File "/usr/lib/python3/dist-packages/mailman/app/membership.py", line 169, in handle_SubscriptionEvent send_welcome_message(mlist, member, member.preferred_language) File "/usr/lib/python3/dist-packages/mailman/app/notifications.py", line 52, in send_welcome_message 'list:user:notice:welcome', mlist, language=language.code)) File "/usr/lib/python3/dist-packages/mailman/model/template.py", line 188, in get name, lookup_context, **substitutions) File "/usr/lib/python3/dist-packages/mailman/database/transaction.py", line 85, in wrapper return function(args[0], config.db.store, *args[1:], **kws) File "/usr/lib/python3/dist-packages/mailman/model/template.py", line 109, in get contents = protocols.get(actual_uri, **auth) File "/usr/lib/python3/dist-packages/mailman/utilities/protocols.py", line 38, in get response = requests.get(url, timeout=REQUEST_TIMEOUT, **kws) File "/usr/lib/python3/dist-packages/requests/api.py", line 75, in get return request('get', url, params=params, **kwargs) File "/usr/lib/python3/dist-packages/requests/api.py", line 60, in request return session.request(method=method, url=url, **kwargs) File "/usr/lib/python3/dist-packages/requests/sessions.py", line 533, in request resp = self.send(prep, **send_kwargs) File "/usr/lib/python3/dist-packages/requests/sessions.py", line 646, in send r = adapter.send(request, **kwargs) File "/usr/lib/python3/dist-packages/requests/adapters.py", line 516, in send raise ConnectionError(e, request=request) requests.exceptions.ConnectionError: HTTPConnectionPool(host='localhost', port=8000): Max retries exceeded with url: /postorius/api/templates/list/<MAILINGLIST>/list:user:notice:welcome (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f0b5ce8d8d0>: Failed to establish a new connection: [Errno 111] Connection refused')) Postorius/Mailman is running on port 8001, only Postorius still connecting on port 8000.

DMARC Munging
by Allan Hansen Jan. 30, 2020

Jan. 30, 2020

All, The munged From: header in MM3 still says 'name' via ‘listname’ <‘listaddress’> This caused me and my subscribers a lot of grief in MM2: Some mail clients use the first part up to the From for future key-ahead for new email to ’name’, hiding the address, so what they think is a personal message for ’name’, instead goes to the entire list. Red faces all around. Stephen Thurnbull earlier suggested further munging by replacing the list address in the From: header like this: 'name' via ‘listname’ <‘whoopsieaddress’> Which will return an automated reply explaining the issue. I like this option. How can I get that in? Yours, Allan Hansen allan_hansen(a)icloud.com PS: I always use sender in Reply-To.
