Editing Mailman's text files
by Pete Bell May 7, 2024

May 7, 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. 26, 2024

Feb. 26, 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?

Excessive or fatal bounces issue
by Florin Pasăre Nov. 23, 2023

Nov. 23, 2023

Hello, I've been having some issues lately. We are using Mailman 2.1.15. I've looked over the FAQ but the only thing that I could find is to contact the ISPs and ask to be whitelisted - am I understanding this correctly? Here is a brief description of the issue: Our server hosts 5 listserv, the biggest one counts over 530 subscribed members from 55 different countries. We had received sporadic bounces triggered by emails sent to these lists since the install of the server in 2016, but in the last months the number of bounces we get has increased. We receive these bounce notifications informing us that the given *subscription has been disabled* due to *excessive or fatal bounces *(up to around 30 bounce notifications triggered by a single email sent to one of the listservs). Every time we get such notifications, we untick the bounce under “nomail [reason]" in the admin management site for each of the email addresses that haven been disabled by the system. Furthermore, it has happened several times in the past few months that a number of email addresses have been automatically removed from the listservs (at the same time, from different countries). We have not found an explanation for why this happens or a solution, so the only thing we are able to do is to manually add them back to the listservs. We have also asked these colleagues for which we have received bounces to check whether there is anything blocking the listservs’ emails from their side (note that many of them work in ministries or agencies with strong security features), and to add the server IP to the white list, but the problem persists. Thank you for your time, Florin Pasăre,

Hide list address?
by Ricardo Kleemann Nov. 16, 2023

Nov. 16, 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.

DOS vulnerability, gmail and yahoo
by Karl Semich Sept. 19, 2023

Sept. 19, 2023

Hi mailman-users, So you know, it looks like there is a vulnerability with mailman 2 where a third party can very aggressively spoof password reminder, unsubscription, or other requests using the web interface, queueing tens of thousands of unsolicited messages to any given subscriber. Worse, if this is done to a user of gmail or yahoo, the receiving hosts may block the mailserver’s ip address generally, preventing the delivery of legitimate list content to other subscribers using the same provider. There should probably be a rate limit on the web interface, although I understand mailman 2 is no longer developed.

Question regarding message-ids
by Ralf Hildebrandt Sept. 14, 2023

Sept. 14, 2023

We have a mm2 installation. A user is regular memeber on two lists: * A mail goes to both lists. * That mail is distributed via both lists. * The mail is delivered twice (to an exchange server), in two SMTP sessions, to the same user adress. I get two positive delivery confirmations. * since the message-id is identical, exchange is performing duplicate message elimination Since the mails are in fact NOT identical (different Subject -- each lists adds their own [foo] and [bar] prefix), I'd very much prefer a new message-id for the distributed mails. I'm sure I can hack something up in Postfix, but is there an easy way (tm)? -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netz | Netzwerk-Administration Invalidenstraße 120/121 | D-10115 Berlin Tel. +49 30 450 570 155 ralf.hildebrandt(a)charite.de https://www.charite.de

Problem with outlook.com
by pau.baiges＠csuc.cat Sept. 12, 2023

Sept. 12, 2023

We have a problem with some Outlook users who on the list return this error: Error: ‎550 5.6.0 CAT.InvalidContent.Exception: ExchangeDataException, Decoding of header Subject failed+ADs- raw value: +AFs-Ens+AF0- +AD0-?eucgb2312+AF8-cn?q?An+AD0-A8+AD0-A4lisis+AF8-i+AF8-adequaci+AD0-A8+AD0-AE?+AD0-; cannot handle content of message with InternalId 3332894626847, InternetMessageId There are Outlook users who, with the same subject, send the email correctly and everyone receives it, but there are others who get this error.

Identifying a subscriber from a masked FBL report
by Russell Clemings Sept. 11, 2023

Sept. 11, 2023

I'm trying to track down (and unsubscribe) a list member who keeps reporting list posts as spam. I have %(user_address)s and %(user_name)s in msg_footer, but the feedback loop reports are masking the local part of the user's address. The user_name appears to be empty. I tried both %(user_optionsurl)s and %(user_delivered_to)s but they're masked too. The FBL seems to be masking anything that looks like an email address and even some things that don't. Suggestions? I do have shell access but can't see where I could make any appropriate changes (aside from which my Python skills are minimal or less). -- =============================================== Russell Clemings <russell(a)clemings.com> ===============================================

Footers as Attachments
by David Andrews Sept. 7, 2023

Sept. 7, 2023

Some of my users have complained about getting an attachment with each message. The attachment seems to be the footer fort the list. It also looks like this may be an Outlook thing. Is this true? Is there anything to be done to change it. I would guess that changing to text-only messages would do it, but that isn't necessarily a popular option either. Dave
