Editing Mailman's text files
by Pete Bell 08 May '24

08 May '24

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 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 16 Nov '23

16 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

Munge without CC or Reply-To
by Diez 22 Feb '22

22 Feb '22

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

Re: Charter occasionally bouncing mail
by Michael Reeder -- Hygeia MS 30 Nov '21

Regarding Microsoft-hosted email -- they also frequently block ALL lists on the basis that the email was not specifically addressed to the recipient. I wrote a tutorial for my users about how to add my list addresses to the safe senders list (known elsewhere as a white list). It is found here: https://www.clinicians-exchange.org/fix-hotmail-and-outlook-to-allow-safe-m… At the time I was mainly thinking its a Hotmail problem -- but it's any email address on any domain hosted at Microsoft. They also seem to do this for any email forwarded from another address -- very annoying when lots of email is being auto-forwarded. Does not seem fixable by any setting that either the email account holder or the email company administrator can adjust. Michael Reeder Hygeia Counseling Services michael(a)hygeiacounseling.com (Now auto-forwarded to an address hosted at Microsoft so I have to safe list every blessed new sender!) ------ Original message------ *From: *Jon Baron *Date: *Mon, Nov 29, 2021 6:57 AM *To: *Jayson Smith; *Cc: *mailman-users(a)python.org; *Subject:*[Mailman-Users] Re: Charter occasionally bouncing mail I have had a lot of experience with these things. Here are some observations. I have a list of 4000+ subscribers around the world. I have SPF and DKIM but not DMARC. (I never say much point in DMARC, and it does not seem necessary.) Right now every single one of the 4000+ subscribers accepts the mail, most of the time. Occasionally I get msssages (from Europe) saying that the mail has been blocked because it is a "high probability of spam" or "looks like spam". This drives me crazy. These spam-blocking systems are unregulated. They are like snake oil. They should not be blocking mail without telling the recipients, and this is what happens. A few times, Microsoft has started blocking mail to ALL addresses with domains of outlook, hotmail, msn, or live. Sometimes this was the result of what you are talking about. I was told to sign up for various things, including "sender support": https://sendersupport.olc.protection.outlook.com/snds/ You can get data on what proportion of your mail counts as spam (if you have enough mail, as we do). When they block mail, you can complain: https://support.microsoft.com/supportrequestform/8ad563e3-288e-2a61-8122-3b… (the one that works for me) or just https://support.microsoft.com/supportrequestform/ If you complain, you will get an automatic reply saying that your problem does not qualify for mitigation and that they are almost always correct. Then you have to respond to that. After a few rounds of this, you will get a response from what seems to be a human being, who will tell you that they are taking your problem very seriously, yada yada. The last time this happened, they were completely blocking all make for over a week, because my IPV4 address (the one they use) was part of a range of addresses from which spam was being sent. Of course, I have only one ipv4 address (from a cloud server, Linode). The problem seems fixed for now, but I am warning new subscribers not to use Microsoft-controlled addresses. Of course they won't tell you HOW they decide that something is spam, as this information would just make it easier for spammers. (But I don't see what is so bad about spam. You just delete it; it helps if possible spam goes to a spefific folder, but any system I've seen makes many mistakes both ways, except spamassassin, which rarely makes a false positive. The real problem is phishing, and there have been no randomized control trials to see whether any system can immunize people against that. I doubt that these spam detectors do it effectively.) Some references: https://answers.microsoft.com/en-us/outlook_com/forum/all/hotmailoutlook-bl… https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… And there are several things like this: https://mxtoolbox.com/blacklists.aspx But the list called UCEPROTECT3 (I think) is now, happily, widely ignored, because it is based on spam coming from a large range of ipv6 addresses on a cloud server. Spamhause does something like this too, but you can fix it by getting a "proper" ipv6 address that specifies the range ("/64" at the end).
