Dear Mailman3.com users! All the servers have been upgraded to the latest code in the last few days. It's now possible to activate Google's reCAPTCHA on the Postorius sign-up page to protect the server from spam registrations. Since this option might break GDPR, it's disabled by default.

New options: moderators' protection from spam and users' default time zone
by Mailman3.com April 28, 2025

April 28, 2025

Dear Mailman3.com users! All the servers have been upgraded to the latest code in the last few days. The new version introduces a few new options you can use to improve your experience with Mailman: ✉️ The "Automatic Responses" page of a list settings now has the option "Admin notify held with attachment." It is set to "Yes" by default, which matches Mailman's default behaviour. This behaviour might trigger anti-spam traps in moderator mailboxes due to the attached message. It can now be set to "No" so moderators won't get held messages attached while still getting notifications. ✉️ New users, registered in Postorius, get UTC as their default time zone. This can now be configured to another timezone via a support request. ✉️ For the users of the Dedicated plan, we can now disable username and password-based login completely in favor of SSO or social-based login.

Mailman3.com servers upgrade: Postorius improvements
by Danil Smirnov Dec. 26, 2024

Dec. 26, 2024

Dear Mailman3.com users! All the servers have been upgraded to the latest code in the last few days. The most noticeable new feature is the Members, Held messages, and Subscription requests indication on the List overview page. Kudos to Bernie Hoeneisen from Ucom Standards Track Solutions GmbH for this great contribution! Another important change is that DMARC mitigation is now enabled by default for new mailing lists, reflecting the status quo in email tech. We also set "Notify owner on bounce increment" to "Yes" by default now to improve informing list owners about unsubscription reasons. Of course, those settings can be reverted to previous defaults when creating a new list. Happy Holiday Season! New IT
