[MM3-users] Re: DKIM signatures with message footers or subject prefixes

by Stanisław Findeisen

Thank you for your clarification. I am now wildcard (*) DKIM-signing the (arbitrary) From: address domain with the host domain key. However my mailing list is a virtual host (actually there are several of them), which is different than the host domain. Do you know if such a setup is harmful? Or if there is a way to select the VHOST key? This is Postfix + OpenDKIM. With DMARC mitigation action = Replace From: and DMARC Mitigate unconditionally = Yes the VHOST key gets selected, which also results in (existing and) valid DMARC. Perhaps this setup makes it easier to pass through the spam filters?... But the cost is the abused From:.

[MM3-users] Re: templates

by Odhiambo Washington

Isn't that the same thing as not having them in the FS? I read (and asked questions about) templates almost 10x before I got to understand the locations and how MM uses them. It's not easy to understand the ones in the FS while the ones in the DB are easy. Then again, one needs to know that Postorius only writes to the DB.

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.

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.

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.

[MM3-users] Re: Issues with @gmail.com addresses

by Mohsen Masoudfar

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. I searched ourlist, but could not find a hint. It seems mailmanclient has a method to deal with this, but I could not find the details.
