by Barry Warsaw May 20, 2026

May 20, 2026

Public bug reported: When a message from Mailman gets routed to an IMAP server (e.g. for archiving or administration), we need a sieve rule to do proper routing. E.g. for dovecot. ** Affects: mailman Importance: High Assignee: Barry Warsaw (barry) Status: Confirmed ** Changed in: mailman Status: New => Confirmed ** Changed in: mailman Importance: Undecided => High ** Changed in: mailman Assignee: (unassigned) => Barry Warsaw (barry) ** Changed in: mailman Milestone: None => 3.0.0a6 -- Add sieve rules to route messages properly to IMAP server https://bugs.launchpad.net/bugs/582525 You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman.

[Bug 2047306] [NEW] Modify the calling domain of Google reCAPTCHA
by Gentry Deng May 18, 2026

May 18, 2026

Public bug reported: Hello, I noticed that GNU Mailman uses Google reCAPTCHA for filtering bot traffic, unfortunately the default calling domain for Google reCAPTCHA is www.google.com. And www.google.com is inaccessible in some areas, such as the Chinese mainland. Google provides an alternative, they also provide reCAPTCHA access service at www.recaptcha.net. So can you modify the calling domain of Google reCAPTCHA to www.recaptcha.net? Google Developer Documentation: https://developers.google.com/recaptcha/docs/faq#can-i-use-recaptcha- globally Best regards, Gentry ** Affects: mailman Importance: Undecided Status: New -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/2047306 Title: Modify the calling domain of Google reCAPTCHA To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/2047306/+subscriptions

[Bug 1252575] [NEW] The Mail<->News gateway doesn't honor moderation or *_these_nonmembers for messages gated from usnet.
by Mark Sapiro May 18, 2026

May 18, 2026

Public bug reported: Messages gated to a list from usenet bypass all the checks in Moderate.py. It is appropriate to bypass generic_nonmember_action because many usenet posts will be from nonmembers of the list, but if the sender is a moderated member or a nonmember matching one of the *_these_nonmembers filters, those things should be honored. ** Affects: mailman Importance: Medium Assignee: Mark Sapiro (msapiro) Status: In Progress -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1252575 Title: The Mail<->News gateway doesn't honor moderation or *_these_nonmembers for messages gated from usnet.

[Bug 1417093] [NEW] list of users approved for any list on the site
by Stephen Turnbull May 18, 2026

May 18, 2026

Public bug reported: Some sites would like to allow a specified list of users to subscribe without administrator approval to any list on the site. For sites with many users, many lists, and a lot of turnover, approving all subscriptions is a lot of work. In many applications it would probably be a better idea to have a member plugin for the enterprise member database, but not all sites will be that sophisticated, or they may worry about the security implications of exposing those databases to Mailman. ** Affects: mailman Importance: Undecided Status: New ** Tags: feature mailman3 -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1417093 Title: list of users approved for any list on the site To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1417093/+subscriptions

[Bug 1774826] [NEW] Feature request: simple captcha
by Oscar Racle May 18, 2026

May 18, 2026

Public bug reported: Suggest to include a simple captcha that (unlike reCAPTCHA) does not involve feeding data to the internet advertising and surveillance industry. This could be a simple arithmetic captcha entirely implemented in python without any contact to 3rd party servers. Such a mechanism should be sufficient to keep out ordinary spambots. ** Affects: mailman Importance: Undecided Status: New -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1774826 Title: Feature request: simple captcha To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1774826/+subscriptions
