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.

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.

Newbie User
by David Elliott 17 Mar '22

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 16 Feb '21

16 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 09 Sep '20

09 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

Very strange issue With Mailman + Exchange(?)
by Bruce Johnson 29 Jul '20

29 Jul '20

I am not sure how to figure this out. Lengthy explanation: Internally in our Exchange server, that address is a distribution group whose only member is the actual <list-name>@lists.pharmacy.arizona.edu, because the Mailman server is not our mail server. (we have a mildly complicated setup: hybrid OnPrem and O365 exchange + Barracuda spam appliance in front of all of it, which is our actual SMTP server. Outgoing email from the list server bypasses Exchange and is sent directly to the Barracuda SMTP server. For two users and ONLY these two users, somewhere between them and mailman and back, the Mailman list is being expanded to put all the members of the list on the CC line. It then gets held for approval with a ’too many addresses’ message. I have watched them send an email to the affected list; the list address is NOT in their local address cache, and they are NOT entering any other addresses in the email other than the list address. The only address that appears on the email in their Sent folder is the list address. Other users in our organization can send to these same lists without this happening. In fact one of the affected users can send to *other* lists on our server with no problems. These are two different lists. I don’t know that this is specifically a Mailman problem (because it’s only happening with specific users) but I cannot see how list members are getting stuffed on the CC line otherwise; because Exchange only knows the list address, not the members; only Mailman does. TLDR: Somehow the all the list addresses are getting stuck onto the list message which then holds it for approval for ’too many addresses’. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs

Mailman 2.1.34 released
by Mark Sapiro 10 Jul '20

10 Jul '20

I am pleased to announce the release of Mailman 2.1.34. This is a minor bug fix release and has updates to the Spanish i18n. See the attached README.txt for details. As noted Mailman 2.1.30 was the last feature release of the Mailman 2.1 branch from the GNU Mailman project. There has been some discussion as to what this means. It means there will be no more releases from the GNU Mailman project containing any new features. There may be future patch releases to address the following: i18n updates. security issues. bugs affecting operation for which no satisfactory workaround exists. Mailman 2.1.34 is the fourth such patch release. Mailman is free software for managing email mailing lists and e-newsletters. Mailman is used for all the python.org and SourceForge.net mailing lists, as well as at hundreds of other sites. For more information, please see our web site at one of: http://www.list.org https://www.gnu.org/software/mailman http://mailman.sourceforge.net/ Mailman 2.1.34 can be downloaded from https://launchpad.net/mailman/2.1/ https://ftp.gnu.org/gnu/mailman/ https://sourceforge.net/projects/mailman/ -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

Mailman error sending email when Mailman not installed
by markandrewellis＠gmail.com 30 Jun '20

30 Jun '20

Hello I have recently taken over management of a website for my advanced motorcyclists' group. The site is Wordpress based and we are setting up a mailing list using the WP Mailster plugin. However, when sending an email to the list I receive the following error: "This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: pipe to |/usr/local/cpanel/3rdparty/mailman/mail/mailman post committee_mbeam.org.uk generated by committee(a)mbeam.org.uk local delivery failed" As stated in the thread title, Mailman is not installed in Cpanel as our hosting provider does not allow it to be used. Speaking to the previous webmaster it seems that Mailman was used with a previous hosting provider, so I'm wondering if some configuration may have been copied across with the website to the new host server which could cause this error. I have searched the directories and found several one directory and several files with Mailman in the title or text. The directory is /.cpanel.mailmanconfig and contains files for each of the lists that were used with Mailman and each file contains text similar to: {"owner": ["lists(a)mbeam.org.uk"], "private_roster": 1, "archive_private": 0, "advertised": 0, "subscribe_policy": 2} There are two directories files in the cpanel cache from 2012 and 2017 that refer to mailman-list-usage. To test if any of these files were causing the problem, I renamed them with a bak prefix, but I still receive the same error. Siteground support has looked at the site for me and said that there does not appear to be any config file that should not be there, but as WP Mailster is third party software and they do not support Mailman, they can't help further. I should add that we have used phplist and that works without any errors. Any advice will be gratefully received.

"Message discarded" "spamdetect", why?
by Johannes Rohr 23 Jun '20

23 Jun '20

Hi, yesterday, I member tried multiple times to send a to a list, from a roundcube webmailer which is running on the same host as mailman itself. The message is in plain text without any attachments, no HTML either. Yet it was silently discarded by mailman. In /var/log/mailman/vette I find the message Jun 19 21:02:42 2020 (14835) Message discarded, msgid: <************@***>' list: ******, handler: SpamDetect The filter configuration for the list is: filter_mime_types = '' pass_mime_types = """multipart/mixed multipart/alternative text/plain""" filter_filename_extensions = """exe bat cmd com pif scr vbs cpl""" pass_filename_extensions = '' Can anyone say why mailman considered it to be spam? BTW, all messages are scanned by rspamd anyway, which does an outstanding job at spam detection, so mailman's rudimentary spam detection mechanism seems rather superfluous to me. Can't one just turn it off altogether? Cheers, Johannes

Occasional duplicate messages from a mailman list?
by howardpa＠sonic.net 21 Jun '20

21 Jun '20

I have a list with about 25 members. One of the members on the list gets duplicate messages most of the time. And yes, the '.. no duplicate' option is checked for the list. My only clue is that sometimes one of the headers in replying to a message sent by the list has 'bounce' in it: From: tcr-owners <tcr-owners-bounces+rblahblah=hotmail.com(a)lists.sonic.net> on behalf of Shelley Brown <sblahbla(a)mcn.org> What is generating the 'bounce'? All email addresses on the list have been checked for authenticity, and the option of sending 'bounces' to me (the admin) is checked and I don't routinely get any. thanks for taking a look at this post, Howard

DNSException: Unable to query DMARC policy
by Johannes Rohr 21 Jun '20

21 Jun '20

Dear all, lately my mailman instance has applied the DMARC workarounds an increasing number of mails. Looking into /var/log/mailman/error, I see a large number of messages containing the string "DNSException: Unable to query DMARC policy for [address]: connection timed out". We are running Ubuntu 18.04 LTS, the current mailman version is from 2018. Except from installing the occasional security updates, I don't see what has changed, that might be responsible for these timeouts. What command does mailman use to query for the DMARC status of an address? Cheers, thanks a lot for any hint... Johannes
