Editing Mailman's text files
by Pete Bell May 8, 2024

May 8, 2024

Hi. I'm a new member of this group but have been running an email list with Mailman for a long time. I am now setting a list up again and want to give a "look and feel" to the list which has more branding of my user group as a whole, and less of a Mailman-feel. I seem to remember that besides editing the public HTML pages, it is possible to edit the text files which Mailman automatically sends out for certain needs (such as 'approve.txt', 'adminsubscribeack.txt', 'invite.txt', and so on). A. Is this still the case? B. If so, where can I find them? (in case they've changed from the ones I have from long ago). C. Where do they need putting, so that Mailman can use them again? It's important that I should tell you that Mailman on my webhosts servers is a "server-wide" installation, and I don't get to edit anything which other clients to their servers need. This would be only for my own use, and as such I need to know where these files go in my own webspace, and how to get Mailman to use them instead of the default ones. I should also say that I have done this before, so unless the facility to do this has been ditched in recent years, I *should* still be able to do it ! Does Mailman perhaps look for these files somewhere in my webspace (which I have to give a specific name), and if it doesn't find them it goes on to find its default versions of these files? Thanks in advance for your help. Pete Bell, UK

Running two list with same email prefix
by Andrea Cappelli Feb. 27, 2024

Feb. 27, 2024

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 Nov. 17, 2023

Nov. 17, 2023

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 Aug. 10, 2022

Aug. 10, 2022

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

Re: [Mailman-Users] Automate Moderator Functions

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

Munge without CC or Reply-To
by Diez Feb. 22, 2022

Feb. 22, 2022

Hello. I'm new at this list. I'm trying to setup a list (I'm not the site admin), and I'd like to use Munge From setting, but I'd like not have Reply-To field or CC field, but I suspect is not possible. I was testing with anonymous_list, but the problem is that only a certain member should send some kind of calls, but with anonymous_list anyone could send it. I'm setting up with 2.1.23 version. Regards and thanks in advanced and sorry for my bad english

subscription flood, redux
by Karl Berry July 31, 2021

July 31, 2021

I was just hit with a subscription flood, along the lines of https://mail.python.org/pipermail/mailman-users/2014-May/076880.html https://bugs.launchpad.net/mailman/+bug/1082746 I've mitigated the current attack, but it's happened before and will happen again. I'm already using SUBSCRIBE_FORM_SECRET. I also saw Mark's patch in the thread above to disable subscriptions for a particular list, which is helpful. Still, trying to look ahead, I have two further questions: 1) The above mailman-users thread refers to using fail2ban. This sounds sensible. Does anyone have a a working fail2ban filter they can share for this? I'd rather not write one from scratch; my previous attempts at doing so have been rather uneven. (Not the easiest thing to search for, since fail2ban itself uses mailman for its mailing lists, it seems. I couldn't find anything, at any rate.) 2) At least in my cases, the floods try to subscribe the same address over and over (and over and ...). It occurs to me that mailman could silently discard a request to subscribe an address foo(a)bar.com if foo(a)bar.com already has a pending subscription -- that is, not sending out the confirmation request. Would this be doable? Mark, anyone? Although I realize that has downsides, for myself at least I'd prefer to minimize the backscatter pain for the random targeted addresses. Real people who are failing to subscribe can write the owner. Thanks in advance, Karl
