[MM3-users] Re: Mailman 3 Web Application Startup Time or Availability - 502 Bad Gateway and Postorius

As far as I can tell, this looks like a normal web server (nginx?) error. If I try visiting the Mailman 3 server location again in a web browser shortly thereafter, I still might get a 502 Bad Gateway error. If I wait a while longer (maybe a minute or more?), the Mailman 3 web application appears to load as expected. What is your configuration for accessing Mailman. I gather you are proxying from nginx to something. Is that something gunicorn or uwsgi? You mention gunicorn but this can be confusing as mailman core's REST API uses gunicorn, but that is separate from the web server's wsgi interface to Django. In any case, this issue is probably with whatever nginx is proxying to (gunicorn or uwsgi) and not with Django or Mailman core. > I've tried looking at the gunicorn documentation (https://docs.gunicorn.org/en/stable/index.html) and searching online (including in this Mailman3 mailing list) to see if there's something that can be done to fix this issue. The closest thing I can find for now is advice for something that, while possibly being technologically unrelated, includes the idea of "warmup requests", which makes me think of simply setting up some sort of script to periodically load a page on the Mailman 3 web application in order to keep it more available for visitors (https://stackoverflow.com/a/57056170) That's certainly a possibility and may be a solution. It would be simple enough to set up an hourly cron to do a curl or wget to retrieve example.mailman.site/mailman3/lists/ and see if that helps. > Is there a setting or something in any of the Mailman 3 related programs that could help with keeping the Mailman 3 web application up and running more often without having to resort to making an ongoing, automated request to the Mailman 3 web application? Nothing that I'm aware of, but if so, it would most likely be a gunicorn or uwsgi setting rather than something in Mailman or Django, although it could be that gunicorn or uwsgi is timing out in trying to connect to Django in which case it could be a Django issue, but not one I've heard of. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

Continuing the troubleshooting, I came around a very long list, over 3000, of "banned addresses" on the 'problem list'. I wonder if there is a way to delete them programmatically.

(One could argue that) Depends on what kind of spam filtering if any you have on incoming mail to list.rc.org. > Is my rc.org service provider at fault for sending the bounce message to the server instead of the to the original sender? Absolutely not. The envelope sender of the mail was set by Mailman to <list>-bounces+hansen=rc.org(a)list.rc.org in order to enable automated bounce processing. rc.org correctly sent the bounce to the envelope sender. > Is Mailman at fault for thinking that the bounce message was caused by a list message FROM me, instead of a bounced message TO the list owner? Arguably, yes, but not based on FROM. FROM has nothing to do with it. The message was sent TO you so if it bounces, it is a message to you that bounced, so you are the one bouncing this message. All Mailman knows is a message was sent to you and it bounced so it's your address that is bouncing. It doesn't matter whether this was a post to the list that bounced or a message to <list>-owner. A bounce is a bounce. Note that this list's bounce processing is very aggressive. If you got removed from the list after one bounce, the list must have Bounce score threshold = 1 and Bounce disable warnings = 0. You might consider adjusting these. There is an easy fix for this. Set `verp_probes: yes` in mailman.cfg. Then when your bounce score reaches threshold, instead of disabling/removing you, Mailman will send a probe message to you. It will only disable/remove you if the probe bounces which it presumably won't. Another avoidance would be to use an address for the owner which is not the address of a member. Then if the owner address bounces, nothing is done because the bouncing address isn't a list member. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
