Migrating from debian package to Virtualenv
by Ryan Morash 09 Jun '20

09 Jun '20

We currently have our Mailman3 instance installed using the packages in Debian's repository. We want to migrate over to a virtualenv setup as described here: https://docs.mailman3.org/en/latest/install/virtualenv.html. Is there any thing we should be aware of for migrating data?

django-mailman3 1.3.4 bugfix release
by Abhilash Raj 05 Jun '20

05 Jun '20

Hey everyone, There was a critical bug reported yesterday which would cause users to get 404 pages instead of their list options page. Upon investigation, it was found that the bug was related to bumping of Mailman Core's API version to 3.1 in django-mailman3 1.3.3 release. Because this bug can cause problems accessing several pages in web interface, we have a quick bugfix release for you. If you have already upgraded to 1.3.3 and don't wish to do another upgrade/restart, you have an option to run the command below to avoid the bug: $ python manage.py clear_cache -a This should invalidate the cache entries which cause the 404 bug. The new release is available through PyPI at: https://pypi.org/project/django-mailman3/1.3.4/ The changelog is available at: https://gitlab.com/mailman/django-mailman3/-/blob/master/README.rst Finally, as usual, you can update to the new release using pip: $ pip install django-mailman3==1.3.4 -- thanks, Abhilash Raj (maxking)

duplicate dkim headers w/ AWS SES

Periodically, I've seen these errors from few senders, and wondering if community has a idea? Mailman - 3.3.1rc1 Tom Sawyer "554 Transaction failed: Duplicate header 'DKIM-Signature'" while sending AWS-SES as the MTA? Possible to strip from postfix? I've submitted a AWS ticket.

Emailing a list from the list server
by Mark Dadgar 01 Jun '20

Ok, I admit I am baffled by this one. I cannot email a list from an account on the list server itself (for example, programmatically by script, but also manually) using mail / mailx / mutt / etc from the command line. The emails just disappear into the ether. I can email other arbitrary addresses just fine, including real users hosted on that server. Here’s the postfix main.cf section for mailman3: owner_request_special = no transport_maps = hash:/var/lib/mailman3/data/postfix_lmtp local_recipient_maps = proxy:unix:passwd.byname $alias_maps hash:/var/lib/mailman3/data/postfix_lmtp relay_domains = ${{$compatibility_level} < {2} ? {$mydestination} : {}} hash:/var/lib/mailman3/data/postfix_domains What obvious thing am I missing? - Mark ----- mark(a)pdc-racing.net | 408-348-2878

Header Filters
by Peter Adebahr 01 Jun '20

01 Jun '20

Hi *, we are trying to dispose of automatic replies like "out of office" etc. For these ends, we have set Header to "subject" (w/o quotes) Pattern to ".*out.of.office.*" Action to "Hold for moderation" However, these mails are passed through to the list. How is this to be set to become effective? Thank you and have a good week Peter
