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 28 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

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.

For some reason the crontab for mailman is gone. When I try run crontab for mailman on crontab.in there is no error but when I run 'crontab -l -u mailman' it says there is no crontab. Can someone tell me how to fix this? TIA.

mailman user problem
by Dennis Putnam 22 Mar '22

22 Mar '22

I don't know what happened but mailman is no longer working (CentOS 7). I don't think it is mailman per se but I don't know where else to turn for help. I am feeding mailman using fetchmail from gmail.com which has been working fine for eons. For some reason fetchmail no longer works as I get this error: Old UID list from pop.gmail.com: <empty> After considerable research I THINK I have traced the problem to the mailman account since fetchmail runs as mailman via cron. It appears that the crontab for mailman is gone and I cannot 'su - mailman' to run 'crontab' on 'crontab.in'. Although isn't that supposed to happen automatically? Nor can I run fetchmail as mailman. I get the error: This account is currently not available. The passwd file entry is: mailman:x:41:41:GNU Mailing List Manager:/usr/lib/mailman:/sbin/nologin I think it has always been that way but I'm not sure since '/sbin/nologin' means there is no shell and is why I am getting that error. I don't, at this point, see how it could have ever worked. In any case I need some help figuring out why mailman is getting that error. FWIW, if I run 'passwd -S mailman', I get this: mailman NP 2022-03-19 -1 -1 -1 -1 (Empty password.) TIA

> I am feeding mailman using fetchmail from gmail.com Have you done whatever changes need to be made to your "fetchmail" settings to enable OAUTH2 authentication for your gmail login? Google disabled third-party application access on March 11th, and requires access to be using OAUTH2 or 2FA now. I have no idea if fetchmail can do OAUTH2, I do know that getmail can do it, but it appears you have to renew things every seven days. Sigh. Cheers, Gary B-)

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

Messages being delivered to administrators who are not subscribed.
by Mark Dale 14 Mar '22

Hi, I have just created a new list and the posts from/to subscribers are being received and delivered as expected. All is well there. However the messages are also being delivered to the administrators who are not subscribed. And if the administrator is a subscriber, they receive two copies of the post. Have I missed a setting, or have I screwed up the plumbing somewhere? Nothing is leaping out at me from the logs. Any advice on where I should be looking would be much appreciated. Thanks, Mark PS.
