Debugging mass invitations using web page interface...
by The Mailing List Server Admin Sept. 5, 2019

Sept. 5, 2019

Dear Mailman Cognoscenti, I'm helping one of my list owners send out 5K plus invitations to students to subscribe to his mailing list. Our current configuration: Mailman v2.1.20 RHEL v5.11 Semdmail v8.13.8 Apache v2.2.3 Since this was the first time doing this, I suggested breaking the batch input into 3 groups, 50, 500, and the rest. The 50 went fine, as did the 500, but the largest batch gave him a generic web server error: > Internal Server Error > > The server encountered an internal error or misconfiguration and was > unable to complete your request. > > Please contact the server administrator, root(a)conundrum.unh.edu and > inform them of the time the error occurred, and anything you might > have done that may have caused the error. > > More information about this error may be available in the server > error log. I looked at the logs and I couldn't find anything that hinted at what went wrong. So I asked the owner to send me the last back and I'd give it a try. I wrote a script that removed folks already subscribed to his list and split the remaining subscribers up into 6 files with a thousand records each. I just tried uploading the 1st batch of 1K, with the following options: Subscribe these users now... (*) Invite Send welcome message... (*) No Send notifications... (*) No And entered a 7 line paragraph explaining the invitation. I ended up having the same error happen. Looking at the Mailman logs, I can't see any difference before or after my submission. In the HTTPD logs, I see: >> [Fri Aug 26 19:59:23 2016] [warn] [client 132.177.215.132] Timeout >> waiting for output from CGI script >> /usr/local/mailman/cgi-bin/admin, referer: >> https://lists.unh.edu/mailman/admin/campus.connection/members/add >> [Fri Aug 26 19:59:23 2016] [error] [client 132.177.215.132] >> Premature end of script headers: admin, referer: >> https://lists.unh.edu/mailman/admin/campus.connection/members/add So is there an inherent limit to the number of invites that can be submitted via the web form? As a work around, how would I do large invites on behalf of the owner from the command line, including the 'extra text' that is allowed via the web interface? -- Cordially, the UNH Mailing List Server Admins Bill Costa, senior admin (603) 862-3056

changing domains on Mailman implementation
by Keith Seyffarth Sept. 20, 2018

Sept. 20, 2018

Is there an efficient way to change the domain name that mailman is affiliated with? I have two mailing lists that were created for an organization before that organization had their own domain. At the time the organization was sure they did not want their own domain and would not be getting a domain. Since then, they have chosen to get a domain and set up a web site. I would like to move their mailing lists onto their domain. It looks like the process for this is: 1) get the list of subscribers 2) delete the mailing list from the one domain (losing the archives) 3) create the mailing list on the new domain 4) subscribe the list of subscribers This process doesn't seem too difficult, but I would prefer to keep the archives, if possible. Both domains are on the same server, running CentOS7 and PLESK 12.5, if that makes a difference. Thanks, Keith

non-subscribers getting through--email address in "Real Name"
by Matt Morgan Aug. 1, 2018

Aug. 1, 2018

On one of my lists I'm seeing some spam from non-subscribers getting through. It appears that the trick is to put a subscriber's address in the "real name" of the sender. E.g., this got through, without being held for moderation, on a list with generic_nonmember_action = discard (emails of the innocent obfuscated): *From:* "xxx(a)johnxxx.com <jgl(a)johngreenwaltlee.com>" <enrollment(a)ekonek.com> *Date:* July 18, 2018 at 5:27:24 PM CDT *To:* <listname(a)server.org <osg-l(a)cool.conservation-us.org>> *Subject:* *[OSG-l] No. PL-01-17923 AIC Objects Specialty Group Discussion* *Reply-To:* My List's Name <listname(a)server.org <osg-l(a)cool.conservation-us.org>> Account Summary: --------------------------- Invoice No: No. PL-01-17923 Billing Date: Jul 19, 2018 Due Date: Jul 22, 2018 Amount Due: 1,047.48 Download DOC: etc. (I'm avoiding sharing the links that follow). xxx(a)johnxxx.com IS a subscriber on the list. However enrollment(a)ekonek.com is not. Yet this message went straight through, as if it had been sent by a subscriber. I've looked at the archives of mailman-users and it looks like--from a very old discussion--that a) this cheap trick should not be sufficient to allow the message through b) the content of the message as delivered to the list may not reflect the exact contents/metadata of the message as it was sent. Still, I don't really know what else could be going on here, or how to investigate. Suggestions? Thanks! Matt

bounce notification to owner from non members?
by Adam Morris Aug. 1, 2018

Aug. 1, 2018

Hi all, I receive about 8 bounce messages a day for one of my lists from people trying to post to it who aren't members. The list is set up as private so not sure how these spammers find it. I've been to the bounce page but can't work out how to stop these messages but allow bounce messages from members?

What does mailman do with a POST?
by Bernie Cosell Aug. 1, 2018

Aug. 1, 2018

I'm trying to submit a form or two from a program and I can't quite understand Mailman's form handling, this with Mailman 2.1.23. What I've done is a little program that does something simple: it first authenticates [and gets the appropriate cookies], then I GET the mass-removal page [to get its csrf_object. Then I do a simple POST with just three form fields: csrf_object=> <whatever it was in the GET of the page> unsubscribees => the email address, 'setmemberopts_btn => 'Submit Your Changes' The response I get back is the original page - no error and no success, just the mass-removal page again. It is what would happen if you clicked on the submit button without giving it anything to do I've also tried a similar POSTing with every field from the form included, and always the same: a 200 response and I get the mass-removal page back again. I'd look at the code, but I'm a perl guy -- never messed with python. What does Mailman do to when receiving a POST to decide if there's something to do or not?

Change of subdomain
by Eggert Ehmke July 31, 2018

July 31, 2018

Hello, until recently I had my mailman web configuration in a directory in my www domain, like www.mydomain.de/mailman. Now I changed the structure to have an URL like lists.mydomain.de. I also changed the apache configuration and the /etc/mailman/mm_cfg.py file. This kind of works, I can access my admin panel fine. But some internal urls like the mailing list archive still refer to the old www url. What must I do to clean that up?

Mailman 2.1.X and HTTPS
by Jayson Smith July 26, 2018

July 26, 2018

Hi, I'm currently using 2.1.26. Recently I had LetsEncrypt add lines to my Apache configuration to redirect browsers from HTTP to HTTPS URLs. This morning I found that this doesn't seem to work well with Mailman database admin pages, I couldn't get Mailman to reject a held message until I commented out those Apache config lines. Is there a way to make Mailman work using HTTPS? My reason for the redirect is that I'd heard that browsers, in particular Chrome, are going to start warning about insecure sites. Does this mean if any URL begins with HTTP people will have to click through warnings, or is just the fact that HTTPS is available good enough, even if the user or link didn't specify HTTPS? Thanks, Jayson

Argh. Postfix/Mailman compatibility on Gentoo
by Phil Stracchino July 25, 2018

July 25, 2018

<caerllewys(a)caerllewys.net>: Command died with status 2: "/usr/lib64/mailman/mail/mailman post caerllewys". Command output: Group mismatch error. Mailman expected the mail wrapper script to be executed as group "mailman", but the system's mail server executed the mail script as group "nobody". Try tweaking the mail server to run the script as group "mailman", or re-run configure, providing the command line option `--with-mail-gid=nobody'. I'd swear I fixed that *AT LEAST* once...... The easy solution: 1. In /etc/postfix/main.cf: mail_owner = postfix default_privs = mailman 2. Restart Postfix Done. -- Phil Stracchino Babylon Communications phils(a)caerllewys.net phil(a)co.ordinate.org Landline: +1.603.293.8485 Mobile: +1.603.998.6958

Mailman 2.x to 3.1.x Migration
by Ryan McClung July 25, 2018

July 25, 2018

Hey All, I haven't read anything on gitlab about whether or not this has been finalized. Is there a migration process available? I also read about scripting it but unfortunately I can't find any resources on a way to do so. Can anyone provide me with a best-practices on how to migrate? Ryan
