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 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

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.

Reply-to addresses
by Michael Welch 29 Mar '22

29 Mar '22

Hello friends. We are using Mailman through Dreamhost, which doesn't allow us to change server-based list configurations, we only have access to the Admin's normal Options pages. After years of working fine, we'd recently been having bouncing problems specifically with gmail addresses. Thinking this was Dreamhost's problem, and not mine, I queried Dreamhost support, and they looked over a bounced message. Their suggestions are pasted below. I changed from_is_list to Munge From but now the reply to headers have both the list address and the original sender's address. So I assume the original sender gets sent two copies of responses, one from the list and the other directly to them. I've spent some time over the years trying to train them to not use Reply to All to avoid that double message situation, and now it's happening even with just a regular Reply. I'm hoping I can fix this easily. I know a little about this stuff, but I'm basically just a list manager, not a full-on sysop, so please be gentle in your terminology and instruction. From Dreamhost support: >Taking a look into the 're-wrenches-re-wrenches.org' list, the bounce >errors point to possible DMARC issues with the list post going out. But, >the 're-wrenches-re-wrenches.org' list does not look to have 'Munge From' >enabled on the list right now, so you'll want to log into the list and >enable that on the 'General Options' page for that list. > >Along with that, the list sub-domain didn't have our SPF, so I've added >it for you since the domain is managing DNS services with us as well: > >lists.re-wrenches.org. 300 IN TXT "v=spf1 mx >include:netblocks.dreamhost.com include:relay.mailchannels.net -all" > >That was setup on the 'Websites' > 'DNS Settings' page on your account >for the 're-wrenches.org' domain. > >Having both above set will help to better the outgoing relays of the >posts, so set the 'Munge From' and let us know if you're still seeing the >same bounce as before.

Auto Discard messages FROM list address?
by Bruce Johnson 25 Mar '22

25 Mar '22

I cannot think of any reason the list should be mailing to itself; I’m wondering about putting the list address on the ‘always discard’ list in Privacy Options > Sender Filters (just had to go through and discard another one of those stupid fake ‘I hacked your computer and watched you look at porn’ extortion spams from dozens and dozens of lists; which would be quite the feat for a virtual mailman server :-) These always come through addressed FROM the address they’re sent to: From:mylist@example.com To:mylist@example.com Is there any reason I should NOT add the list address to that group? -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs

Plus addressing
by robertowenberendt＠gmail.com 22 Mar '22

22 Mar '22

Does the list support plus addressing? Google and O365 support plus addressing. This allows someone to subscribe as myself+lists(a)mycompany.com when their real email address is myself(a)company.com. The problem is that when they reply, or generate a new message, it may be held or rejected because it is coming from an address different than they subscribed with. I am aware of the hack at: https://wiki.list.org/DOC/How%20can%20I%20post%20from%202%20or%20more%20add… However this does not appeal to the tinfoil hat crowd who thinks you are just going to sell both addresses. Nor do I want to explain to the masses this hack.
