Could Mailman3 act like a private forum?
by andrew＠fsf.org 06 May '18

06 May '18

Hello Mailman3 users and maintainers, I'm wondering whether it would be possible for Mailman3 to act like a private forum. I know that Mailman3 has private lists and may allow for custom authenticators. However making some lists private seems to be different than making all list signups and archives public to those who are able to log in, but hidden from all users who cannot. Would Mailman3 be able to act like a forum that hides or shows lists based on whether someone is logged in? Thanks, Andrew

django-mailman3 update causing errors
by Darren Smith 02 May '18

02 May '18

Hello, In attempting to update our mailman3/postorius/hyperkitty installation, I have run into an error after upgrading the django-mailman3 project. Our webui is being run through supervisord. The command being run is this: /<path>/mailman3/conda/envs/mailman3_ext/bin/waitress-serve --listen=localhost:8787 webui.wsgi:application The error I'm getting is pretty long, but most of it appears to be usage instructions. Here are what I believe to be the pertinent parts: Error: Bad module 'webui.wsgi' Usage: waitress-serve [OPTS] MODULE:OBJECT <lots and lots of usage instructions> There was an exception (ImportError) importing your module. It had these arguments: 1. No module named error Any thoughts on why updating django-mailman3 would cause this? Thanks! -Darren

Hyperkitty Archives Empty
by jon.kokko＠us.fujitsu.com 02 May '18

02 May '18

I've installed the mailman bundle located here (https://github.com/iomarmochtar/mailman3_ei) and, minus a pip package or two, it was straightforward. Mail & list functionality appears to be working well but I have no archives/thread discussions after posting messages. Delivery, etc.. is all good. Can you offer some suggestions on how to debug the archiving piece? Thanks, ./JK

Rejecting held emails
by Darren Smith 26 Apr '18

26 Apr '18

Hello, We recently had a phishing message make it through our spam filters and arrive at a mailing list. The good news is that since it was not from a list member it was in the held message queue. I was able to find the message in the var/messages directory by searching for a keyword in the subject. However, after rejecting the message from Postorius, the message doesn't seem to be removed from the var/messages directory. Is this expected behavior? I know that infosec people won't be too happy about a phishing email sitting around on our disk. (Infosec guys are notoriously paranoid. :) ) Is there some sort of cleanup process that would remove these messages? If not, does this pose an issue where over time disk usage will creep up? This could be a pretty significant problem if that is the case. What do you think, sirs? -Darren

Disabling Gravatar
by Marvin Gülker 26 Apr '18

26 Apr '18

Hi everyone, I want to make you aware of a potential privacy problem in Mailman's Hyperkitty. Under the upcoming EU General Data Protection Regulation (GDPR)[1], which will be in force as of 2018-05-25, it is illegal to transmit data to third parties without a right to do so. Without going into the details, the inclusion of third party services into one's website is usually deemed such a transmission, and unless one has explicit consent of the user (e.g., by an optional (!), unticked ticking box) this is normally illegal (if one targets EU users). The GDPR does not affect private and family use (Art. 2(2)(c) GDPR), but the exact reach of that clause is yet to be determined; it certainly does not exclude company use of Mailman. I've found it's possible to disable the social login providers quite easily (we had this discussion here on the mailinglist recently), but I don't see an option to disable Gravatar. If there is one, please enlighten me, but anyway I want to propose this as a feature request against Hyperkitty. A GDPR-compliant implementation of Gravatar in Mailman would look like this: * In order to not transmit website visitor's data (IP address, browser info, etc) to Gravatar, Hyperkitty has to request the avatar image itself and not leave that to the user's browsers to do. In other words, the HTTP GET request needs to come from the server running Hyperkitty and the user's browser then just requests the avatar from the Hyperkitty server. Most likely easiest way to do this is to pre-download the avatar when an email is archived. * In order to not transmit the subscribers' data (email address, allows Gravatar to track the subscriber) to Gravatar illegally, the retrieval of the avatar image from Gravatar has to be disabled by default. Instead, an option needs to be added to the subscriber's control panel which he has to actively enable in order to have his Gravatar downloaded and thus used (privacy-by-default rule). I'm not saying Gravatar tracks people and sells the information gathered, though I have doubts on how Automattic makes money with the service. I'm just outlining the legal duties under the upcoming GDPR for service owners, which are independant of how Automattic processes the data in this specific case. Please don't dismiss this as some side feature not needed. The fines that can be imposed on service owners due to violation of the GDPR are very high (up to 20,000,000 € [that's 20 million euros, really]).

Mailman not able to process "big" requests
by Jonas Felber 24 Apr '18

24 Apr '18

Hi, We migrated from mailman2 to mailman3 a week ago. Since then we are unable to send messages the our students through the mailing list. Here are some symptoms: 1. I go to mass subscribe and subscribe 400 emails 2. I click subscribe, the browser (in my case safari) tries to load the page for a few seconds 3. The request times out 4. Once the service becomes responsible again, I see that only part of my emails got subscribed (~50 in this case). For me this really looks like the emails are sent on the "web-thread" that gets killed once the request times out. Looking at this https://gitlab.com/mailman/postorius/blob/master/src/postorius/views/list.p… <https://gitlab.com/mailman/postorius/blob/master/src/postorius/views/list.p…> seems to confirm my suspicions. Some quick overview of our infrastructure: The TCP endpoints are: browser -> haproxy in kubernetes-entry-router -> nginx in kubernetes-ingress -> nginx in mailman -> mailman We mitigated the issue by giving it more CPU power and increasing the timeouts in one of the nginx endpoints. We also have a problem with sending out emails to "large" (>50) groups, as they seem to not getting sent out at all. Do you have any idea what the problem here could be? We would be really glad if you can help us getting our mailman up and running, as I currently have to send emails out by "hand". I will happily provide you with more details about our configuration, just let me know what you need.

Another interesting error...
by Darren Smith 24 Apr '18

24 Apr '18

So it appears that there was a message sent to one of our mailing lists that was put into the held message queue. However, when attempting to go to the message to do the moderation, the web page returns and Error 500. Looking in the mailman log, I found this: Apr 23 14:21:02 2018 (17878) REST request handler error: Traceback (most recent call last): File "/opt/mailman3/conda/lib/python3.6/wsgiref/handlers.py", line 137, in run self.result = application(self.environ, self.start_response) File "/opt/mailman3/conda/lib/python3.6/site-packages/mailman/database/transac tion.py", line 50, in wrapper rtn = function(*args, **kws) File "/opt/mailman3/conda/lib/python3.6/site-packages/mailman/rest/wsgiapp.py" , line 214, in __call__ return super().__call__(environ, start_response) File "/opt/mailman3/conda/lib/python3.6/site-packages/falcon/api.py", line 227 , in __call__ responder(req, resp, **params) File "/opt/mailman3/conda/lib/python3.6/site-packages/mailman/rest/post_modera tion.py", line 167, in on_get resource = self._make_collection(request) File "/opt/mailman3/conda/lib/python3.6/site-packages/mailman/rest/helpers.py" , line 159, in _make_collection for resource in collection] File "/opt/mailman3/conda/lib/python3.6/site-packages/mailman/rest/helpers.py" , line 159, in <listcomp> for resource in collection] File "/opt/mailman3/conda/lib/python3.6/site-packages/mailman/rest/post_modera tion.py", line 157, in _resource_as_dict resource = self._make_resource(request.id) File "/opt/mailman3/conda/lib/python3.6/site-packages/mailman/rest/post_modera tion.py", line 100, in _make_resource make_header(decode_header(resource['subject']))) File "/opt/mailman3/conda/lib/python3.6/email/header.py", line 174, in make_he ader h.append(s, charset) File "/opt/mailman3/conda/lib/python3.6/email/header.py", line 295, in append s = s.decode(input_charset, errors) UnicodeDecodeError: 'gb2312' codec can't decode byte 0x87 in position 2: illegal multibyte sequence It LOOKS as if there might be a character in the email somewhere - possibly in the subject or sender fields? - that is somehow unexpected. I am attempting to find the held message - can someone point me where I can go to see the message so that I can see what might be causing the problem? -Darren
