Running two list with same email prefix
by Andrea Cappelli 27 Feb '24

27 Feb '24

Hi all, I'm running a mail server with Debian Lenny, MTA is Postfix and i will use postfix-to-mailma.py script to run list I would set up Mailman for running mailing list with same email prefix on different domains, obvious with different list names For example we have ml.domain1.com and ml.domain2.net, i would like to have LISTADDRESS LISTNAME tech(a)ml.domain1.com tech-ml.domain1.com tech(a)ml.domain.2.net tech-ml.domain2.net In this way i can have the same address on differente domains and Mailman (my version is 2.1.11) can distinguish between lists because the list name is different. The list name will be also used to access web interface, so we have http://ml.domain1.com/mailman/admin/tech-ml.domain1.com http://ml.domain2.net/mailman/admin/tech-ml.domain2.net Is possible to accomplish this task? Any idea?

Hide list address?
by Ricardo Kleemann 17 Nov '23

17 Nov '23

Hi, Is there any way to configure Mailman such that, for an announcement-only type list, when a message is sent to the list, the To: shows the member's address, rather than the list address? Some list software allows the ability to hide the list address itself, so that address is not advertised. I couldn't find any configuration specific to that.

Using cronjob to remove and add members to a mailing list
by Jerry Barnabee 10 Aug '22

10 Aug '22

I want to be able to run a cronjob on my server that uses a php script to add new users and/or remove users from a mailing list. Not having any luck finding any simple examples. My thought is that the php script would get email addresses from a database (which I can do) and then feed them to a mailman command line to either add or remove a user. The cronjob is entered via Cpanel. Have several cronjobs that modify databases but have never tried something that would actually execute a unix command. Thanks, Pineyscripter

Hi, i`m trying to reject messages bigger then MAX_MESSAGE_SIZE. I configured my Hold.py was described bellow: replaced hold_for_approval(mlist, msg, msgdata, _ MessageTooBig(bodylen,_mlist.max_message_size)) with rej = MessageTooBig(bodylen, mlist.max_message_size) _ raise Errors.RejectMessage, rej.reason_notice_ The message was rejected, but the sender dont receive any notify about that. The mailman vette log too. How can i solve this? Thanks, André Dennis Putnam wrote: > >I am getting back to this and I have a question about maintenance. What >is the correct way to modify this so that it will not get destroyed by >updates? There are two ways to proceed. You can modify Mailman/Handlers/Hold.py itself, but before overwriting it, make a "diff -u" between the base Hold.py and your modified version to use as a patch to apply after any upgrade. A better way is to leave Hold.py unchanged and make your own edited version as say Mailman/Handlers/MyHold.py. Then you can replace the base Hold.py Module with your MyHold.py by putting GLOBAL_PIPELINE[GLOBAL_PIPELINE.index('Hold')] = 'MyHold' in mm_cfg.py. Note that if you are going to do this, and you want also to move MimeDel before Hold, you must either put the above line after the lines GLOBAL_PIPELINE.remove('MimeDel') GLOBAL_PIPELINE.insert(GLOBAL_PIPELINE.index('Hold'), 'MimeDel') in mm_cfg.py or put it before, but then also change GLOBAL_PIPELINE.insert(GLOBAL_PIPELINE.index('Hold'), 'MimeDel') to GLOBAL_PIPELINE.insert(GLOBAL_PIPELINE.index('MyHold'), 'MimeDel') I recommend the former as in # # Put MimeDel ahead of Hold so "too big" is based on content filtered # message. # GLOBAL_PIPELINE.remove('MimeDel') GLOBAL_PIPELINE.insert(GLOBAL_PIPELINE.index('Hold'), 'MimeDel') # # Replace Hold with local version # GLOBAL_PIPELINE[GLOBAL_PIPELINE.index('Hold')] = 'MyHold' Since mm_cfg.py survives upgrades, this should survive. >Also does this same procedure apply to other automatic rejections such >as implicit destination? >On 9/24/2012 8:43 PM, Mark Sapiro wrote: >> >> To automatically reject or discard messages that exceed the list's size >> limit, find the section of the Mailman/Handlers/Hold.py that ends with >> the lines >> >> >> if bodylen/1024.0 > mlist.max_message_size: >> hold_for_approval(mlist, msg, msgdata, >> MessageTooBig(bodylen, >> mlist.max_message_size)) >> # no return >> >> (there is one wrapped line in the above) and replace >> >> hold_for_approval(mlist, msg, msgdata, >> MessageTooBig(bodylen, >> mlist.max_message_size)) >> >> with >> >> rej = MessageTooBig(bodylen, mlist.max_message_size)) >> raise Errors.RejectMessage, rej.reason_notice >> >> to reject the message or with >> >> raise Errors.DiscardMessage >> >> to discard the message.

Hi, I am a newbie to Mailman and cpanel and I need some help, please. I have set up a mailing list for my tennis club (about 300 on list) and it seems to work ok BUT each recipient only sees the mailing list name rather than his own email name in the 'to' box. One of the recipients recently did a 'reply to all' and consequently sent his reply to the whole mailing list. I'm sure there must be a way to prevent this but I can't find it! David Elliott

Add "sender's name/email" to BODY of mail as header?
by Mal 17 Feb '21

17 Feb '21

I want all mails sent to the list to come from the list's email address... But, in this case, if the user forgets to sign their name at the bottom of their mail body, effectively the mail to the list is anonymous...! Is there a way to add the user name (or email address) to the top of each mail so that the mails have the name of the sender, while the mail itself comes from the list address? I have looked high and low for an answer, but noone seems to have the solution. Thank you! Mal

Mailman CGI Error-Group mismatch error
by Wang, Mary Y 10 Sep '20

10 Sep '20

Hi, I received the following error this morning. So I rerun configure again with the following command: ./configure --with-cgi-id=apache --prefix=/var/mailman. I'm still getting the same error. Is there any place that I can look for so that I can debug this problem better? Perhaps, looking at the config history file or something. Any other places that I can check the cause of this error? "Mailman CGI error!!! The Mailman CGI wrapper encountered a fatal error. This entry is being stored in your syslog: Group mismatch error. Mailman expected the CGI wrapper script to be executed as group "nobody", but the system's web server executed the CGI script as group "apache". Try tweaking the web server to run the script as group "nobody", or re-run configure, providing the command line option `--with-cgi-gid=apache'." Thanks Mary

Find a smtp server to send out emails
by Leon 20 Mar '20

20 Mar '20

Hi, This problem is not caused by mailman, but I still want to give it a shot here. I'm hosting a mailing list on top of mailman. Emails are supposed to be sent out by AWS ses. However, ses requires that sender address must be verified, which leads to a problem that emails sent by subscribers to mailing list cannot be sent to other subcirbers, since their addresses are not verified. And it is impossible to verified every subscriber. Are there smtp service providers allowing unverified email address to send out emails, or do I have other solutions? Thanks. Leon

Installing Mailman on a Debian system with Apache 2.4.2, CGI error!
by Jayson Smith 05 Dec '19

05 Dec '19

Hi, This is a weird one. I think of myself as knowing my way around Mailman pretty well for a user/admin/installer/upgrader. I'm upgrading to a Debian 9 system from CentOS 6.5. Debian's Apache configs took a bit of getting used to, but I actually like them better. It uses Apache 2.4.2. I wanted to install Mailman from source, since the latest version is 2.1.26, Debian has 2.1.23, and IIRC that's too old to have some screen reader optimizations I want. So I built, installed, all working well. I copied over the Mailman config from my CentOS system to use in Apache, making some changes so it'd work under 2.4.2. Here it is: -------------------- # # httpd configuration settings for use with mailman. # ScriptAlias /mailman/ /usr/lib/mailman/cgi-bin/ <Directory /usr/lib/mailman/cgi-bin/> AllowOverride None Options ExecCGI Require all granted </Directory> Alias /pipermail/ /var/lib/mailman/archives/public/ <Directory /var/lib/mailman/archives/public> Options Indexes MultiViews FollowSymLinks AllowOverride None Require all granted AddDefaultCharset Off </Directory> # Uncomment the following line, to redirect queries to /mailman to the # listinfo page (recommended). # RedirectMatch ^/mailman[/]*$ /mailman/listinfo -------------------- The problem is that the CGI isn't working. If I go to http://temphostname/mailman/listinfo/mailman for example, Apache says /usr/lib/mailman/cgi-bin/listinfo/mailman doesn't exist. If I just go to /mailman/listinfo I get an Elf binary thrown at me, rather than the page saying there are no advertised lists. If I do the same thing from the server using the Lynx web browser, I get the same binary thrown at me, with a page title, "Mailman CGI error!" It sounds to me like Apache 2.4.2 isn't seeing that /usr/lib/mailman/cgi-bin is, in fact, CGI scripts, and is trying to treat them like regular files. Has something else changed between Apache versions? Thanks, Jayson

Trouble with Mailman 2 and Postfix 3.1 - Fixed
by Alan Ordway 24 Oct '19

24 Oct '19

Thought I would share this problem I ran into and the solution incase anyone else has it. Running Mailman 2.1.20 on Ubuntu 16 and a recent update to postfix stopped my lists. In my syslog I was seeing a message similar to: Oct 24 16:43:59 mailman postfix/smtpd[18686]: NOQUEUE: reject: RCPT from mailman.ihmc.us[184.182.233.xxx]: 451 4.3.0 <user(a)ihmc.us>: Temporary lookup failure; from=<podcast-bounces(a)mailman.ihmc.us> to=<user(a)ihmc.us> proto=ESMTP helo=<mailman.ihmc.us> As it turns out Postfix 3 tightened up on relaying. In my postfix/main.cf I had both mynetworks_style = subnet mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 I finally found at <http://www.postfix.org/BASIC_CONFIGURATION_README.html <http://www.postfix.org/BASIC_CONFIGURATION_README.html>> that if mynetworks is present then mynetworks_style is ignored. So I commented out mynetworks and changed mynetworks_style = host and now mail from lists is being delivered again. Hope this helps someone else. -- Alan M Ordway

mailman not functional
by Steven Jones 20 Oct '19

20 Oct '19

Hi, Yesterday we had a major network outage that lasted 2 hours+ This morning I find that the mailman server has "stopped working" I have restarted mailman and now the server but mailman is not processing any emails. The load in top is 0.00 ~0.01 sort of thing, no no disk i/o, no action at all, disks are not full. ssh takes a long time to login but there is no load to cause this. I can see python is running in top but at like 0.3%. I run mail me@work and postfix sends fast so postfix seems OK, its like Mailman is in a coma, its has chocked to death but its heart is still beating....just seems odd. What can I do here? regards Steven

zero-length config.pck file
by David Newman 19 Oct '19

19 Oct '19

mailman-2.1.29_6, FreeBSD 12.0-RELEASE-p10 After an unscheduled power cut by our hosting provider, one of the mailing lists hosted on this server came back up with a config.pck file containing 0 bytes. The file's timestamp corresponded to the time of the power loss. As a result, bin commands such as 'list_lists' would return a corrupt database error, and overnight cron jobs wouldn't run. This was only for one list; other lists on the same server were OK. I've restored the config.pck file from a backup and things seem to be OK now. Just checking, though: 1. Have others encountered config.pck corruption from power loss? 2. (putting on my tinfoil paranoid hat) Is there any chance the file corruption occurred due to an intrusion attempt, and not the power loss? Thanks! dn

How to stop auto discarding when whitelisted and automatic discarding set to 0?
by Tom Corcoran 18 Oct '19

18 Oct '19

Apologies if this is a FAQ but I could not find the info. I have some mailing lists setup on cpanel. One address I have added to my whitelist in spamassain. I also have no auto discard set, with "Discard held messages older than this number of days. Use 0 for no automatic discarding." set to 0. However, emails from this address come in as auto discarded. I'd like to prevent that in the future and have the email delivered as normal. Is there an additional setting I need to configure? Thanks!

confirm_delay_cleared = yes vs. Mailman bounce management
by Ralf Hildebrandt 17 Oct '19

17 Oct '19

Today I received a lot of unsubscription notifications for a certain list. I grew suspicious and had a closer look. I found that Postfix was retrying the delivery for a lot of domains behind the same MX and was (finally) reporting the delivery after a long time of queueing for that MX host. This was due to my non-default setting: confirm_delay_cleared = yes After sending a "your message is delayed" notification, inform the sender when the delay clears up. This can result in a sudden burst of notifications at the end of a prolonged network outage, and is therefore disabled by default. The side effect was that these notifications increased the bounce score, although the delivery was successful. -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netzwerk Campus Benjamin Franklin (CBF) Haus I | 1.

Intendation of threads in archive too high
by Peter Wetz 15 Oct '19

15 Oct '19

I fiddled around with adding a timestamp to the (threaded) view and therefore edited HyperArch.py and archidxentry.html In HyperArch.py I changed the following lines at aroudn line 1073 as follows: d = { 'filename': urllib.quote(article.filename), 'subject': subject, 'sequence': article.sequence, 'date': time.strftime("%d %b %Y %H:%M:%S", time.localtime(float(article.date))), 'author': author } archidxentry.html looks like this: <LI> %(date)s  <A HREF="%(filename)s">%(subject)s </A><A NAME="%(sequence)i"> </A> <I>%(author)s </I> However, see that the thread in the archive of my list is indented at level 3. The thread should be at the very left of the screen (where the bullet points typically start), but this is not the case as can be seen on the screenshot: https://imgur.com/a/ab9WSuz I inspected the HTML code and can see that there are three <ul> tags before the first entry starts. However, I don't know where they come from. As can be seen above, they are not part of archidxentry.html. I also took a look at archidxhead.html and archliststart.html, but have seen nothing suspicious there. Can you help me please?

Re: [Mailman-Users] No archive files but 2 lists taking up 50MB in cPanel?
by Tom Corcoran 15 Oct '19

15 Oct '19

Thanks, Brian & Steve! I feel some context would be useful. I solely use mailing lists so both myself and my wife can get emails from schools, sports clubs, bills, etc. All emails that come in I want to forward to our 2 addresses with no archive so as far, as I am concerned ongoing admin having to accept messages from new addresses, is overkill and I would avoid doing it and accept all messages if that was possible. Also, sometimes some of the sports clubs for my kids attach a pdf. I have only edited the bare minimum of the mailman settings. 1. I looked at "Scrub attachments of the regular delivery message? (Details for scrub_nondigest)" which opens in a new window it's set to no already!2. In content filtering, I turned it on and changed nothing else. Hopefully, #2 means that attachments will now not be archived and I can achieve my goal of zero build-up of any storage with messages passing through? I guess I'll have to wait and see if anything accumulates! Thanks a million, Tom. [for some reason this post of 7+ days ago, never appeared on the list, I may have used the wrong from email] >

No archive files but 2 lists taking up 50MB in cPanel?
by Tom Corcoran 04 Oct '19

04 Oct '19

I have 3 lists, going to mailing list administration and clicking on Go to list archives gives Private archive file not found for all. But in cPanel mailing lists it says: list 1 usage 14.98 MB list 2 usage: 37.72 MB list 3 has usage in KB, which is what I expect. All are I believe setup identically I don't have command line access to my cPanel - just FileManager. How do I find out what these 50+MB are being used for and how do I recover the 50+MB? Thanks!

Mail receipt not working for multiple list members
by jannik.petersen＠posteo.de 01 Oct '19

01 Oct '19

Dear Sir or Madam, Multiple members of our cluster-strategy(a)ndc-cluster.net <mailto:cluster-strategy@ndc-cluster.net> mailing list have reported that they did not receive several emails sent to this list. Un- and resubscribing them did not solve the problem and neither did trying out the multiple options listed in the FAQ. What I did do just now is to disable automatic bounce processing. Could that be somehow related to the problem? Are there any common issues you have encountered that I may not know about and other options that I could try out to solve this problem? Thank you very much in advance for any assistance in this matter. It is greatly appreciated. Sincerely, Jannik Petersen
