Read-only File System

Hello, Several days ago, I posted a message to his list concerning our installation of Mailman 2, and a weird problem that caused messages posted to a list to fail, as /usr/local/mailman/qfiles/in/ was behaving like it was read-only. First off, thanks to everyone who replied with suggestions. While we haven't determined what was causing this issue, we did devise a work-around of sorts. I'm posting it here in case someone else encounters the same issue. The problem that we encountered was that mailman / python regarded /usr/local/mailman/qfiles and all the directories under it to be read-only. They're not - anything else that wants to create a file therein can do so. This was how we fixed it: 1. Stop mailman if it's running. 2. cd /usr/local/mailman . 3. cp -R qfiles /qfiles . (I suspect there are more appropriate places to copy the directory to, such as /var - this worked for us and we stopped messing with it.) 4. mv qfiles qfiles.dist - just in case you ever figure out the real cause and want to reverse all this. 5. ln -s /qfiles qfiles . (That is, create a symbolic link to the /qfiles directory, or wherever you decided to put it.) 6. Start mailman Mailman proved to have no problem writing to the relocated qfiles directory, and everything magically started working. Hope this saves someone from banging their head against a wall, as we very nearly wound up doing. ::Jack

Sharing PHP or Scripts to a list
by patricia traore Nov. 8, 2024

Hi All, I hope that I'm asking in the right place. We have just created a developers discussion public list in our organization with over 47 subscribers. My question is, in case someone shares some php codes in his message, will that code affect the corresponding html page of that message, while browsing the archive of messages publicly from a web browser? Or will pipermail instead display the shared codes as plain text? Thanks, Patricia Traore Project Lead, Maniflex Ltd | maniflexa.com

mm3: Some system is reinjecting mails -- and those mails "pass" moderation but why?
by Ralf Hildebrandt Oct. 24, 2024

Oct. 24, 2024

Hi! We're running postfix-users(a)postfix.org and we're encountering an odd problem: A system is sending mailing list messages that were posted on postfix-users(a)postfix.org BACK to postfix-users(a)postfix.org And these mails simply pass moderation (which is set to the following): Default action to take when a member posts to the list: Default processing Default action to take when a non-member posts to the list: discard (no notification) The headers of the mail (which I put on hold, based on the IP of the sending system): Date: Thu, 24 Oct 2024 11:13:01 +0200 To: postfix-users(a)postfix.org Message-ID: <ZxoPneroJAID0LOm(a)castor.ghen.be> In-Reply-To: <ZxoMla6S1LugyQ9j(a)chardros.imrryr.org> X-MailFrom: geert(a)hendrickx.be X-Mailman-Rule-Misses: dmarc-mitigation; no-senders; approved; emergency; loop; banned-address; member-moderation; header-match-postfix-users.postfix.org-0; nonmember-moderation; administrivia; implicit-dest; max-recipients; max-size; news-moderation; no-subject; digests; suspicious-header X-Mailman-Version: 3.3.9 Precedence: list Content-Type: text/plain; charset="us-ascii" Message-ID-Hash: Z6I2WZCEBC6PUKLVOEVAW3ZU2CDR47AW X-Message-ID-Hash: Z6I2WZCEBC6PUKLVOEVAW3ZU2CDR47AW X-MailFrom: tech(a)turbopush.cn X-Mailman-Rule-Misses: dmarc-mitigation; no-senders; approved; emergency; loop; banned-address; member-moderation; header-match-postfix-users.postfix.org-0; nonmember-moderation; administrivia; implicit-dest; max-recipients; max-size; news-moderation; no-subject; digests; suspicious-header Subject: =?utf-8?B?W+WklumDqOmCruS7tl1bcGZ4XSBb5aSW6YOo6YKu5Lu2XVvlpJbpg6jpgq7ku7ZdUmU6IE9wZW5TU0wgY29tcGlsZSB2cy4gcnVudGltZSB2ZXJzaW9uIHdhcm5pbmc=?= From: Geert Hendrickx via Postfix-users via Postfix-users <postfix-users(a)postfix.org> Reply-To: Geert Hendrickx <geert(a)hendrickx.be>, Geert Hendrickx via Postfix-users <postfix-users(a)postfix.org> So, it's the mail from "Geert Hendrickx" being resent from tech(a)turbopush.cn -- the headers have both "X-MailFrom: tech(a)turbopush.cn" (not a member of the list) and "X-MailFrom: geert(a)hendrickx.be" (definitely a member of the list) Why is the mail being accepted? From: doesn't look right (since it says "postfix-users(a)postfix.org") We're currently stopping these mails, but I think mm3 is not acting correctly here (unless we're missing something) -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netz | Netzwerk-Administration Invalidenstraße 120/121 | D-10115 Berlin Tel. +49 30 450 570 155 ralf.hildebrandt(a)charite.de https://www.charite.de

Do you send more than 5K emails a day? Do you have reverse PTRs? Are you using TLS? Are you using ARC since you are a mailing list?

Problems with Google Workspace
by David Andrews Oct. 9, 2024

Oct. 9, 2024

I run a Mailman installation, 2.1.39 through cPanel. I am having trouble delivering to addresses that are a part of Google Workspace! My mail reports show the mail is accepted, but the users do not get it, and they, or I are seeing no errors. Does Google have mail requirements I am not aware of, we of course have .DKIM, SPF etc. Thanks for any light you can shed onto this! Dave

Odd error during message approval
by Johnson, Bruce E - (bjohnson) Oct. 2, 2024

Oct. 2, 2024

One of our list moderators got the following website error after trying to approve a posting to a moderated list: "Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit." Someone else was able to approve the same message after she logged in to the pending requests page. I could not find any reference to this web server rotor in /various/log/httpd/error_log or ssl_error_log Where does Mailman log it’s http errors and what could cause this error? (I checked the /var/log/mailman logs and did not find anything either.) (Running V 2.1.30 on Rocky Linux, 8.10, installed via the distro packages ) -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs
