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.

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

Add "sender's name/email" to BODY of mail as header?
by Mal 17 Feb '21

17 Feb '21

I want all mails sent to the list to come from the list's email address... But, in this case, if the user forgets to sign their name at the bottom of their mail body, effectively the mail to the list is anonymous...! Is there a way to add the user name (or email address) to the top of each mail so that the mails have the name of the sender, while the mail itself comes from the list address? I have looked high and low for an answer, but noone seems to have the solution. Thank you! Mal

Non-member regexps
by Daniel Krause 11 Feb '21

11 Feb '21

Good Day We are using mailman 3, and would like to whitelist a domain for acceptance of messages as non-members. It seems possible from my online searches, I have also tried with an online python regex tester(https://www.regextester.com/94044), but I have not managed to be successful. Below are 2 examples I have tried ^.+(a)noldor\.co\.za$ ^[a-zA-Z0-9_.+-]+@(?:(?:[a-zA-Z0-9-]+\.)?[a-zA-Z]+\.)?noldor\.co\.za$ ^.+(a)gmail.com$ ^.*gmail\.com$ Regards -- *Daniel Krause* *Head of IT* *Office: **+27 87 238 4238* <0872384238> *Mobile : **+971 55 418 4733* <0971554184733> *Email: **daniel(a)noldor.co.za* <daniel(a)noldor.co.za> *Web: **www.noldor.co.za* <http://www.noldor.co.za/>

Archive Issue -- prune_arch doesn't remove detached attachments?
by Ralf Hildebrandt 22 Dec '20

22 Dec '20

Today I issued "prune_arch -l flohmarkt -d 30" and wondered about the immense size of the corresponding archive directory archives/private/flohmarkt du quickly showed me why: # du -s * | sort -n 4 index.html 4 pipermail.pck 84 2020-November.txt 296 2020-December.txt 332 2020-November 460 database 1168 2020-December 17280164 attachments Shouldn't prune_arch also clean out the "attachments" directory?

Google reCAPTCHA blocked by SELinux on Mailman 2.1.29 (CentOS 8)
by Ole.H.Nielsen＠fysik.dtu.dk 20 Dec '20

20 Dec '20

I have migrated my old Mailman server to a CentOS 8.3 server containing this Mailman RPM package: mailman-2.1.29-10.module_el8.3.0+548+3169411d.x86_64 I would like to enable Google reCAPTCHA in mm_cfg.py as explained in /usr/lib/mailman/Mailman/Defaults.py with: RECAPTCHA_SITE_KEY = xxx RECAPTCHA_SECRET_KEY = yyy I have created the prerequisite V2 keys on https://www.google.com/recaptcha/admin and restarted the mailman service. The Mailman list page now contains a nice "I'm not a robot" frame as expected. However, when I click "Subscribe", the confirmation page says "[Errno 13] Permission denied” (copied from my memory) and the subscription fails :-( It finally dawned upon me that this could be a SELinux issue, since I naturally want Enforcing mode. If I use "setenforce Permissive" the Mailman error goes away! The command "journalctl -t setroubleshoot" tells me: SELinux is preventing /usr/bin/python2.7 from name_connect access on the tcp_socket port 443. (lines deleted) If you believe that python2.7 should be allowed name_connect access on the port 443 tcp_socket by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'python2' --raw | audit2allow -M my-python2 # semodule -X 300 -i my-python2.pp I can confirm that the Mailman error is fixed by this workaround. Question: Is there a proper way to configure this SELinux access for python2.7, rather than making this workaround? Such a solution should be submitted as a bug report to RedHat/CentOS/Fedora. Thanks a lot, Ole

Manually incrementing bounce counters
by Matthew Pounsett 18 Dec '20

18 Dec '20

I occasionally get "Uncaught bounce notifications" where mailman has been unable to figure out which user/list to increment the bounce counters for, but where it's blindingly obvious to me. If it's just one or two bounces I'm happy to leave it alone, but in other cases I'd like to manually trigger the bounce processing lifecycle. Ideally I'd like to be able to just suspend these users as if they had hit the bounce limit for their lists, and let the notification process (and possibly the user's action to unsuspend themselves) take over. Failing that, the next best thing is to manually increment the bounce counter for that list/user combination to trigger suspension that way. Has anyone already got a script around for doing either thing? Failing that, is there some documentation somewhere on the object model that I can use to whip up a `withlist` invocation? The docs on this seem pretty thin. I can't find anything on list.org that describes the methods or variables available for lists or subscribers, or how to access them. The "Site Administrator's Manual" appears to have never actually been written, and the rest of the docs in the Site Administrator's section appear to be FAQs and install manuals, none of which address this (that I can find). The class level documentation returned by pydoc seems like it might be useful here, but there's a lot to wade through since pretty much everything appears to be accessed through the MailList class, and there's no example usage that I've seen so far. I'd prefer to avoid having to go line by line through the code if I can avoid it, so some pointers (to docs or examples I can reverse engineer) would be awesome. Thanks!

Using Mailgun with Mailman
by Jonathan M 09 Dec '20

09 Dec '20

I run Mailman 2 on a shared server. Over the years I’ve had occasional deliverability problems owing to spam from other users. In the long run I hope to migrate to Mailman 3, on a Digital Ocean droplet or similar. In the meantime, I’m looking at maybe using an email sending service. Is it possible to use Mailgun (or alternative services) with Mailman 2/3? Mailgun does its own bounce processing and I wonder how that might tie in with Mailman’s. If it is possible, in what circumstances (if any) is it advisable? Thanks for any advice. Best wishes Jonathan Sent from my iPhone
