[Bug 582525] [NEW] Add sieve rules to route messages properly to IMAP server
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 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

[ mailman-Patches-657951 ] Generate RSS summary in archives

Aug. 19, 2022

Patches item #657951, was opened at 2002-12-23 14:17 Message generated for change (Comment added) made by bwarsaw You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=300103&aid=657951&group_i… Category: Pipermail Group: Mailman 2.2 / 3.0 Status: Open Resolution: None Priority: 7 Submitted By: A.M. Kuchling (akuchling) Assigned to: Nobody/Anonymous (nobody) Summary: Generate RSS summary in archives Initial Comment: Here's a first-draft patch. Things that need fixing: * The generated RSS feed needs to be validated. (It passed the W3C's RDF validator, but RSS validators still need to be checked.) * The date should be given in YYYY-MM-DD format, which requires parsing the .fromdate attribute. * How do I get the URL for an archived message? The generated RSS currently just uses the filename, which is wrong. How do I get at the PUBLIC_ARCHIVE_URL setting? * Getting the most recent N postings is inefficient; the code loops through all of the archived messages and takes the last N of them. We could add .last() and .prev() methods to the Database class, but that's more ambitious for 2.1beta than I like. (Would be nice to get this into 2.1final...) * The list index page should have a LINK element pointing to the RSS file. Please make any comments you have, and I'll rework the patch accordingly. ---------------------------------------------------------------------- >Comment By: Barry A. Warsaw (bwarsaw) Date: 2003-04-18 18:43 Message: Logged In: YES user_id=12800 Andrew, to get the url for the archived message use mlist.GetBaseArchiveURL(), which knows about private vs. public archives, the host name and the list name. From there you should be able to tack on just the part of the path under "archives/private/listname". See Mailman/Handlers/Scrubber.py for an example. Only other minor comment: NUM_ARTICLES can probably go in Defaults.py.in ---------------------------------------------------------------------- Comment By: Justin Mason (jmason) Date: 2003-03-26 16:49 Message: Logged In: YES user_id=935 big thumbs up from me too.

[Bug 1462755] [NEW] qrunner crashes on invalid unicode sequence

I would say that this is actually a bug in python-email, since I think it doesn't make sense to set errors to "strict" rather than something like "replace" when the intention is to parse stuff so free-formed, under-specd and user-controlled as email. Nonetheless, Mailman already sets errors='replace' in some places so it might aswell add it here. ** 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/1462755 Title: qrunner crashes on invalid unicode sequence To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1462755/+subscriptions
