Re: cc'd e-mail addresses rewritten with @invalid.domain
by Williams, Peter B Sept. 23, 2020

Sept. 23, 2020

Hi Mark, Thanks for the help with this! Other list members will also see the e-mail as coming from user(a)invalid.domain<mailto:user@invalid.domain>. I will continue testing the other scenarios and will reply back as soon as possible. Thanks again for the help with this and have a nice day!

For example in the scenario above my e-mail that is cc'd is also a member of listserv(a)lists.test.org<mailto:listserv@lists.test.org>. In this case, where do you see this? i.e., do other list members see it in the message they receive from the list? I don't know why that would be. I'm certain that Mailman is not involved in this and the Williams(a)invalid.domain and Peter(a)invalid.domain addresses are in the Cc: as received by Mailman. > This issue does not occur if the user e-mail address is listed before the mailing list in the cc field. So for example, if the cc in the scenario above contained Williams, Peter; listserv(a)lists.test.org<mailto:listserv@lists.test.org>; it would route properly. Again, I think this is Outlook. What's in the Cc: of the mail that test_user(a)gmail.com<mailto:test_user@gmail.com> receives directly? What happens if you send mail in this way with To: test_user(a)gmail.com<mailto:test_user@gmail.com> cc: other_user(a)gmail.com<mailto:other_user@gmail.com>; Williams, Peter; Again, what's in the Cc: of the mail that test_user(a)gmail.com<mailto:test_user@gmail.com> and other_user(a)gmail.com<mailto:other_user@gmail.com> receive?

Mails are not archived at all -- how to check if Hyperkitty is running or not?
by Franklin Weng Sept. 23, 2020

Sept. 23, 2020

Hi, I set up the mailman3 services and lists, and we can send mail to the list successfully. However in the Archive section I couldn't see anything and all the lists were "inactive" and hence were hidden by default. I confirmed that api_key set in the /etc/mailman3/mailman-hyperkitty.cfg and /etc/mailman3/mailman-web.py is the same. I also confirmed that the apache2 wsgi module has been loaded. In the mailman.cfg database is set to mysql and in the mailman-web.py database … [View More]

cc'd e-mail addresses rewritten with @invalid.domain

Hi, We've recently noticed an issue where users who are cc'd in a message where a mailing list is also within the cc list are getting rewritten a user(a)invalid.domain. This issue looks like it may be related to Outlook and how user names are displayed specifically. Here is an example: To: test_user(a)gmail.com cc: listserv(a)lists.test.org; Williams, Peter; "Williams, Peter" maps to a user e-mail in the Outlook Global Address book. When the message is sent the list will send the message … [View More]

Template path
by Seth Seeger Sept. 21, 2020

Sept. 21, 2020

Hello everyone, I’m running Mailman from Docker containers, without much customization. (Postorius 1.3.3, Core 3.3.1, API 3.1, Python 3.8.5). I’ve created a list:user:notice:welcome template, and when I try to confirm a subscription, I get an error. I followed previous emails on this list which told me to set POSTORIUS_TEMPLATE_BASE_URL in /opt/mailman/web/settings_local.py, but that doesn’t seem to make any difference. (I set it to a different value and the error message didn’t change. … [View More]I also tried setting it in /opt/mailman/core/settings_local.py to no effect. After each change, I restarted mailman-web and mailman-core containers.) From within mailman-web and mailman-core containers, I can reach “mailman-web:8000”.

Redundant and load balanced Mailman3
by Pawel Grzywaczewski Sept. 20, 2020

Sept. 20, 2020

Hi, Can someone share some hints about how to deploy redundant and load balanced Mailman3? What are your recommendations and best practices? For example what components to put on the same VM? Can we have 2VM with Mailman core/Postorious/Hyperkitty/django-mailman/mailmanclient connecting to one (the same) database? How to load balance mail routing (incoming)? Thanks! Paweł
