User settings triggers error

If one of my users (including admin) goes to their user drop-down in the upper-right of Postorius and clicks Mailman Settings, it triggers an error: Here’s the error log: Internal Server Error: /mailman3/postorius/accounts/subscriptions/ KeyError at /postorius/accounts/subscriptions/ 'file' Request Method: GET Request URL: https://mail.pdc-racing.net/mailman3/postorius/accounts/subscriptions/ <https://mail.pdc-racing.net/mailman3/postorius/accounts/subscriptions/> Django Version: 2.2.12 Python Executable: /usr/bin/uwsgi-core Python Version: 3.8.2 Python Path: ['.', '', '/usr/lib/python38.zip', '/usr/lib/python3.8', '/usr/lib/python3.8/lib-dynload', '/usr/local/lib/python3.8/dist-packages', '/usr/lib/python3/dist-packages'] Server time: Tue, 16 Jun 2020 10:31:56 -0700 Installed Applications: ('hyperkitty', 'postorius', 'django_mailman3', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'django_gravatar', 'compressor', 'haystack', 'django_extensions', 'django_q', 'allauth', 'allauth.account', 'allauth.socialaccount', 'django_mailman3.lib.auth.fedora') Installed Middleware: ('django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.middleware.locale.LocaleMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'django.middleware.security.SecurityMiddleware', 'django_mailman3.middleware.TimezoneMiddleware', 'postorius.middleware.PostoriusMiddleware') Traceback: File "/usr/lib/python3/dist-packages/django/core/handlers/exception.py" in inner 34. response = get_response(request) File "/usr/lib/python3/dist-packages/django/core/handlers/base.py" in _get_response 115. response = self.process_exception_by_middleware(e, request) File "/usr/lib/python3/dist-packages/django/core/handlers/base.py" in _get_response 113. response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/usr/lib/python3/dist-packages/django/contrib/auth/decorators.py" in _wrapped_view 21. return view_func(request, *args, **kwargs) File "/usr/lib/python3/dist-packages/postorius/views/user.py" in user_subscriptions 307. memberships = [m for m in mm_user.subscriptions] File "/usr/lib/python3/dist-packages/mailmanclient/restobjects/user.py" in subscriptions 62. for address in self.addresses: File "/usr/lib/python3/dist-packages/mailmanclient/restbase/base.py" in __iter__ 221. for entry in self.rest_data: File "/usr/lib/python3/dist-packages/mailmanclient/restbase/base.py" in rest_data 197. response, content = self._connection.call(self._url) File "/usr/lib/python3/dist-packages/mailmanclient/restbase/connection.py" in call 99. raise HTTPError(url, response.status, content, response, None) During handling of the above exception (HTTP Error 500: b'A server error occurred.

Server 500 error for just one list, just one page
by kelly.close＠lrewater.com June 28, 2020

June 28, 2020

I am having a curious problem with just ONE list management page for ONE list on my server. Every other list I've checked, and every other management page for this affected list, seem fine. But when I go to the Subscribers page for this one list I get a Server 500 error, and I can't find anything in the apache or mailman logs to give me a clue (granted I'm not sure I know for sure where all the different logs are). So specifically this page: https://udfcd-lists.org/mailman3/postorius/lists/alarms-all.udfcd-lists.org… For a list called "alarms-all" obviously. Any ideas? I'm able to review the list, it's members, etc in the PostsgreSQL tables and I'm not seeing any members with funky characters in their address - the one thing I could think of to check. Thanks, ~Kelly

Null sender?
by tom＠gather.coop June 28, 2020

June 28, 2020

Does Mailman generally send email with a null sender? This is what I see in the log: Jun 28 02:37:45 2020 (14588) ('127.0.0.1', 52726) handling connection Jun 28 02:37:45 2020 (14588) ('127.0.0.1', 52726) Data: b'LHLO mail.example.coop' Jun 28 02:37:45 2020 (14588) ('127.0.0.1', 52726) Data: b'MAIL FROM:<>' Jun 28 02:37:45 2020 (14588) ('127.0.0.1', 52726) sender: <> Jun 28 02:37:45 2020 (14588) ('127.0.0.1', 52726) Data: b'RCPT TO:<techque-bounces(a)example.org>' Jun 28 02:37:45 2020 (14588) ('127.0.0.1', 52726) recip: techque-bounces(a)example.org Jun 28 02:37:45 2020 (14588) ('127.0.0.1', 52726) Data: b'DATA' Jun 28 02:37:45 2020 (14588) ('127.0.0.1', 52726) Data: b'QUIT' Notice the empty MAIL FROM. Sendgrid seems to be choking on that because it needs to check if sending domain has been validated. If there is no sending domain it seems to reject. Why does Mailman do this? Can it be changed? I've been trying to find the relevant section of the code to no avail.

Hyperkitty 403 Forbidden Error
by Phil Thompson June 25, 2020

June 25, 2020

I'm in the process of setting up mailman3. The only problem I seem to be having is getting Hyperkitty to archive messages. Rather than the authorisation problems people have previously asked about on the list, I am getting a 403 error... Aug 05 15:38:40 2019 (10229) HyperKitty failure on http://localhost/mailman3/hyperkitty/api/mailman/urls: <html><title>Forbidden</title><body> <h1>Access is forbidden</h1></body></html> (403) Aug 05 15:38:58 2019 (10222) HyperKitty failure on http://localhost/mailman3/hyperkitty/api/mailman/archive: <html><title>Forbidden</title><body> <h1>Access is forbidden</h1></body></html> (403) Any suggestions would be appreciated.

Relaying email from external SMTP server (office365 or Exchange)
by Waqas Ahmed Khan June 23, 2020

June 23, 2020

Hi, I have installed mailman3 with postfix. The server is working fine. To protect the IPs from blacklisting, I want to relay all emails from postfix/mailman to external SMTP servers like O365, Gmail, or our exchange server. Could you please confirm is this possible. And how to do its configuration.

Key Error when clicking on a list
by Jacob Bargery June 21, 2020

June 21, 2020

I looked back and tried to see if this is related to the Filter_Vhost = true error. In the email log I received at the bottom where it lists settings I am seeing Filter_Vhost = false. So I am guessing it is not related I could be wrong though. I can see lists populated that have been created, but when I click to open them it immediately goes to page titled "Server Error" and reading "An error occurred while processing your request.". This is part of the email, I can include the rest with settings if that will help.

Does mailman2 regular_exclude_list equal mailman3 receive_list_copy ?
by sunil soprey June 21, 2020

June 21, 2020

Question: Reduce cross-posting to multiple lists (either BCC: or To: or CC:) Use-case: User sends email ( to: their email) and ( bcc: list1, list2 ) The sender-user and target-user1 (and target-userX) have receive_list_copy = False, and receive_own = True Issue: For mailman 3.3.1, a user receives their email from To:, however target receipients receive multiple copies of the emails. This is different from mailman2 with the regular_exclude_list. Questions: * this is a configuration issue or expected behaviour ? * target-user is a "user" who is member on list1 and list2 (verified via api) * see list-config - any missing? { "acceptable_aliases": [], "accept_these_nonmembers": [], "admin_immed_notify": true, "admin_notify_mchanges": false, "administrivia": true, "advertised": true, "allow_list_posts": true, "anonymous_list": false, "archive_policy": "public", "autorespond_owner": "none", "autorespond_postings": "none", "autorespond_requests": "none", "autoresponse_grace_period": "90d", "autoresponse_owner_text": "", "autoresponse_postings_text": "", "autoresponse_request_text": "", "bounces_address": "duplicate1-bounces(a)mydomain.local", "bounce_info_stale_after": "7d", "bounce_notify_owner_on_disable": true, "bounce_notify_owner_on_removal": true, "bounce_score_threshold": 5, "bounce_you_are_disabled_warnings": 3, "bounce_you_are_disabled_warnings_interval": "7d", "collapse_alternatives": false, "convert_html_to_plaintext": false, "created_at": "2020-05-31T14:43:48", "default_member_action": "defer", "default_nonmember_action": "hold", "description": "", "digest_last_sent_at": "2020-06-04T00:41:35", "digest_send_periodic": true, "digest_size_threshold": 30.0, "digest_volume_frequency": "monthly", "digests_enabled": true, "display_name": "Duplicate1", "discard_these_nonmembers": [], "dmarc_mitigate_action": "munge_from", "dmarc_mitigate_unconditionally": true, "dmarc_moderation_notice": "", "dmarc_wrapped_message_text": "", "filter_action": "discard", "filter_content": true, "filter_extensions": [ "exe", "bat", "cmd", "com", "pif", "cpl" ], "filter_types": [], "first_strip_reply_to": false, "forward_unrecognized_bounces_to": "administrators", "fqdn_listname": "duplicate1(a)mydomain.local", "gateway_to_mail": false, "gateway_to_news": false, "hold_these_nonmembers": [], "include_rfc2369_headers": true, "info": "", "join_address": "duplicate1-join(a)mydomain.local", "last_post_at": "2020-06-04T01:17:13", "leave_address": "duplicate1-leave(a)mydomain.local", "linked_newsgroup": "", "list_name": "duplicate1", "mail_host": "mydomain.local", "max_message_size": 9990, "max_num_recipients": 10, "max_days_to_hold": 0, "member_roster_visibility": "moderators", "moderator_password": null, "newsgroup_moderation": "none", "next_digest_number": 5, "nntp_prefix_subject_too": true, "no_reply_address": "noreply(a)mydomain.local", "owner_address": "duplicate1-owner(a)mydomain.local", "pass_types": [], "pass_extensions": [], "personalize": "none", "post_id": 51, "posting_address": "duplicate1(a)mydomain.local", "posting_pipeline": "default-posting-pipeline", "preferred_language": "en", "process_bounces": true, "reject_these_nonmembers": [], "reply_goes_to_list": "point_to_list", "reply_to_address": "duplicate1(a)mydomain.local", "request_address": "duplicate1-request(a)mydomain.local", "require_explicit_destination": false, "respond_to_post_requests": true, "send_welcome_message": true, "subject_prefix": "[Duplicate1] ", "subscription_policy": "confirm", "unsubscription_policy": "confirm", "usenet_watermark": null, "volume": 1, "http_etag": "\"8ec001cb705f24c19f1a48de5b551a6a9653fcd6\"" }

Is there a "global" max_message_size?

I'm running Mailman under Docker (maxking). I've a test list with a max_message_size set to 0 (unlimited). I know it's not what anyone should be doing in production, but I still want to test this. I've sent a series of messages with increasingly larger attachments to the list. Going up in 5MB increments, I find that while a message with a 15MB attachement gets through to the list members, a 20MB one doesn't. The interesting thing is the message in the mail logs: Jun 19 11:44:50 venus postfix/lmtp[17630]: C0C7928564: to=<mj(a)lists.scss.tcd.ie>, relay=172.19.199.2[172.19.199.2]:8024, delay=109, delays=2.2/0.04/0.01/107, dsn=5.0.0, status=bounced (host 172.19.199.2[172.19.199.2] said: 552 Error: Too much mail data (in reply to end of DATA command)) So 172.19.199.2 is complaining about "Too much mail data". That's the IP address of the mailman-core container. I'm wondering why this is happening, and where the decision is being made, as it seems at odds with the fact that the mailing list has no limit on message size. Would be grateful for any insights, many thanks. Stephen Kenny
