How to delete large numbers of held messages
by lists＠g1fef.co.uk April 21, 2022

April 21, 2022

We had a mail loop on one of our lists and ended up with over 51k messages in pending (held due to post not form a list member) Trying to delete them from the web UI will take forever, as the largest pagination you can view is 200 at a time. Tried to delete them from the Python interactive shell, but it looks like the API times out after a while. Is there another way to delete all these unwanted held posts? The problem comes after executing: <block> reqs = list(adminlist.held) </block> After a couple of minutes it comes back with: <block> Traceback (most recent call last): File "/usr/lib/python3/dist-packages/urllib3/connectionpool.py", line 699, in urlopen httplib_response = self._make_request( File "/usr/lib/python3/dist-packages/urllib3/connectionpool.py", line 445, in _make_request six.raise_from(e, None) File "<string>", line 3, in raise_from File "/usr/lib/python3/dist-packages/urllib3/connectionpool.py", line 440, in _make_request httplib_response = conn.getresponse() File "/usr/lib/python3.9/http/client.py", line 1347, in getresponse response.begin() File "/usr/lib/python3.9/http/client.py", line 307, in begin version, status, reason = self._read_status() File "/usr/lib/python3.9/http/client.py", line 276, in _read_status raise RemoteDisconnected("Remote end closed connection without" http.client.RemoteDisconnected: Remote end closed connection without response During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/requests/adapters.py", line 439, in send resp = conn.urlopen( File "/usr/lib/python3/dist-packages/urllib3/connectionpool.py", line 755, in urlopen retries = retries.increment( File "/usr/lib/python3/dist-packages/urllib3/util/retry.py", line 532, in increment raise six.reraise(type(error), error, _stacktrace) File "/usr/lib/python3/dist-packages/six.py", line 718, in reraise raise value.with_traceback(tb) File "/usr/lib/python3/dist-packages/urllib3/connectionpool.py", line 699, in urlopen httplib_response = self._make_request( File "/usr/lib/python3/dist-packages/urllib3/connectionpool.py", line 445, in _make_request six.raise_from(e, None) File "<string>", line 3, in raise_from File "/usr/lib/python3/dist-packages/urllib3/connectionpool.py", line 440, in _make_request httplib_response = conn.getresponse() File "/usr/lib/python3.9/http/client.py", line 1347, in getresponse response.begin() File "/usr/lib/python3.9/http/client.py", line 307, in begin version, status, reason = self._read_status() File "/usr/lib/python3.9/http/client.py", line 276, in _read_status raise RemoteDisconnected("Remote end closed connection without" urllib3.exceptions.ProtocolError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response')) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/mailmanclient/restbase/connection.py", line 107, in call response = request( File "/usr/lib/python3/dist-packages/requests/api.py", line 61, in request return session.request(method=method, url=url, **kwargs) File "/usr/lib/python3/dist-packages/requests/sessions.py", line 542, in request resp = self.send(prep, **send_kwargs) File "/usr/lib/python3/dist-packages/requests/sessions.py", line 655, in send r = adapter.send(request, **kwargs) File "/usr/lib/python3/dist-packages/requests/adapters.py", line 498, in send raise ConnectionError(err, request=request) requests.exceptions.ConnectionError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response')) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "<console>", line 1, in <module> File "/usr/lib/python3/dist-packages/mailmanclient/restobjects/mailinglist.py", line 123, in held response, content = self._connection.call( File "/usr/lib/python3/dist-packages/mailmanclient/restbase/connection.py", line 135, in call raise MailmanConnectionError( mailmanclient.restbase.connection.MailmanConnectionError: ('Could not connect to Mailman API: ', "ConnectionError(ProtocolError('Connection aborted.', RemoteDisconnected('Remote end closed connection without response')))") </block>

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.

Applying contradicting posting permissions at the same time
by Дилян Палаузов April 18, 2022

April 18, 2022

Hello, I want to setup a mailing list with following properties: All emails with explicit non-members with moderation option “Default Processing” are distrubuted to the mailing list. Emails from members are rejected. As example m(a)example.org is a member, and n(a)example.org is a non-member with Default processing moderation. An email From: m(a)example.org Sender: n(a)example.org shall be distributed, because n(a)example.org is а non-member, who can post. In my configuration however, the email is rejected, because m(a)example.org is a member and members may not post. Is it possible to configure a MM3 mailing list, which accepts the above email, but would reject it, if the Sender: header is missing? Greetings Дилян

The Hotmail complaint saga continues
by Jayson Smith April 15, 2022

April 15, 2022

Hi, Last week I wrote this list about a situation where I'd received an Email from staff(a)hotmail.com with the subject, "complaint about message from MYI.PAD.DRE.SS." Then later I received a second such message, identified both complainants as the same person, let her know she'd be put on No Mail if she did it again, and received a response from her saying she's never marked one of my messages as spam or junk. The other night I received a third such complaint, duly put her on No Mail, and sent her an Email about it. At that point, I was pretty sure these complaints were being generated by some automated process, since they always came in within two to four minutes of the original messages going out. However, this theory was somewhat squashed when she supposedly complained about the very message telling her that due to complaints she was on No Mail…then responded, indicating she has COVID-19 and is putting off everything not critical until later. I sent that message yesterday morning, and the complaint came in this evening, with her response coming about twenty minutes later. This makes me think she's doing something to cause a complaint to be generated, and doesn't realize she's doing it. My questions are as follows: 1. Is Linode, my VPS provider, also receiving these complaints? If so, I'm surprised they haven't at least sent me a notice telling me about them. 2. Does anyone know if having received these complaints might cause Microsoft to be more likely to add my IP to their infamous block list? If they do, I'm going to be in a bad position, because they'd be well within their rights to say, "You've received four complaints within the last three weeks, so no, we won't mitigate anything for you. Get your Email sending practices in order, then maybe someday we'll talk." 3. I haven't ever received such complaints before this situation started on March 24. Is Microsoft noted for somehow generating spurious complaints like this? If so, is that the reason I'm not getting hounded about it from Linode, the "Little Boy who Cried Wolf" situation? Thanks for any thoughts, Jayson

Unsubscribe functionality and Apple Mail
by André-John Mas April 15, 2022

April 15, 2022

Hi, I am not sure if this is the best place to ask, but I am noticing that depending on the mailman server I am subscribed to, Apple Mail shows me an 'unsubscribe' button, while for others it doesn't. One such mailing list where I don't get the unsubscribe button is macports-users(a)lists.macports.org, so I am trying to establish whether the behavioural issue is coming from? Is it from a header issue in the email or a mis-handling by Apple Mail. BTW there does appear to be a "List-Unsubscribe" header from what I can see, though I don't know enough to know if it is as expected. I am using Apple Mail 16.0 on macOS 12.3.1. Their mailman server is 2.1.29. Thanks Andre

List default options on mailman3
by Andre de Azevedo Cunha April 14, 2022

April 14, 2022

The mailman3 config has equivalent options for those of mailman2? ## Archive options # # List traffic archival policies. # Is archive file source for public or private archival? # # legal values are: # 0 = "public" # 1 = "private" archive_private = 1 (Or any way to disable the list archive for default in entire site) # When a new member is subscribed, their initial moderation flag takes # its value from this option. Turn this option off to accept member # postings by default. Turn this option on to, by default, moderate # member postings first. You can always manually set an individual # member's moderation bit by using the membership management screens. # # legal values are: # 0 = "No" # 1 = "Yes" default_member_moderation = 1 Att, --

ARC protocol in Mailman 2?
by Jayson Smith April 13, 2022

April 13, 2022

Hi, I've recently been playing with the OpenARC milter for Sendmail. I have it running, and it seems to be working properly, except for one thing. When a message is sent to one of my Mailman 2 lists, OpenARC adds an ARC set to the incoming message before it ever hits Mailman. Then the message hits Mailman, and on the way out, OpenARC adds another ARC set to the message, this one indicating the ARC validation failed. Now, if I understand the RFC correctly, any ARC-aware MTA that sees this failure is going to treat the entire ARC chain as though it never existed since the most recent ARC set indicated validation failure. If this is the case, then the whole exercise is pointless. Now some questions. OpenARC has a configuration option to treat certain hosts as trusted, and the Man page indicates that if no hosts are listed there, localhost is automatically added. If this is true, I don't know why OpenARC is processing messages on the way out of Mailman, since that should be a localhost to localhost connection. Is OpenARC the best Milter to use with Sendmail for this purpose? Is there something else I'm doing wrong or overlooking? Thanks, Jayson

Hotmail complaint about list message, but complainant says she never marked anything as junk?
by Jayson Smith April 6, 2022

April 6, 2022

Hi, I run a relatively low traffic Email list on my VPS at Linode. Twice within the last two weeks, I've received an Email from staff(a)hotmail.com with the subject "Complaint about message from XX.XX.XX.XX" where XX.XX.XX.XX is my IP. I'm signed up for Microsoft's Junkmail Reporting Program, and this is the first time I've ever received a complaint from them. Using message headers, I've identified the complainant to be the same list member both times. The actual Emails from staff(a)hotmail.com have nothing in the body, and the complained about message as an attachment. Obviously I can't have complaints tarnishing my Email sending reputation, so I contacted her to see if she was legitimately marking messages as spam/junk, or was doing it by accident, etc. Her response is that she has never marked any Emails from my list as spam or junk. In case it matters as far as the user interface goes, her Email address is at the msn.com domain. Obviously *something* has to be causing complaints to be generated, so if she's not doing it, what could be causing this? Are there any automated processes at Microsoft that could cause a complaint of this type to be generated? Is she somehow marking messages as spam or junk without realizing it? Thanks for any thoughts, Jayson

Step by step guide to installing Mailman
by Ali Savas April 5, 2022

April 5, 2022

Hi all, I have a server running Ubuntu. Is there somewhere a good step by step guide on how I can install and set up Mailman on an Ubuntu/Debian server? Possibly also with hints on what to look for during the installation. Quasi a guide for beginners. Many thanks in advance. Kind regards Ali
