Hi, I created a new mailinglist and got during the test-process the following errormessage in my mailman.log after: ...

Missing whitespace in postfix_vmap after mailman genaliases
by Wolfgang Bock Sept. 23, 2020

Sept. 23, 2020

Hi, after creating a new list I got the following errormessage: mailman aliases -> postmap: warning: /var/lib/mailman3/data/postfix_vmap, line 17: expected format: key whitespace value /var/lib/mailman3/data/postfix_vmap # AUTOMATICALLY GENERATED BY MAILMAN ON 2020-09-19 07:44:34 .... xxxxxxxxxxx(a)lists.xxxxxxxxxxxxxxxx.de xxxxxxxxxxx(a)xxxxxxxxxxxxx.de xxxxxxxxxxx-bounces(a)lists.xxxxxxxxxxxxxxxx.de xxxxxxxxxxx-bounces(a)xxxxxxxxxxxxx.de xxxxxxxxxxx-confirm(a)lists.xxxxxxxxxxxxxxxx.de xxxxxxxxxxx-confirm(a)xxxxxxxxxxxxx.de xxxxxxxxxxx-join(a)lists.xxxxxxxxxxxxxxxx.de xxxxxxxxxxx-join(a)xxxxxxxxxxxxx.de xxxxxxxxxxx-leave(a)lists.xxxxxxxxxxxxxxxx.de xxxxxxxxxxx-leave(a)xxxxxxxxxxxxx.de xxxxxxxxxxx-owner(a)lists.xxxxxxxxxxxxxxxx.de xxxxxxxxxxx-owner(a)xxxxxxxxxxxxx.de xxxxxxxxxxx-request(a)lists.xxxxxxxxxxxxxxxx.de xxxxxxxxxxx-request(a)xxxxxxxxxxxxx.de xxxxxxxxxxx-subscribe(a)lists.xxxxxxxxxxxxxxxx.de xxxxxxxxxxx-subscribe(a)xxxxxxxxxxxxx.de xxxxxxxxxxx-unsubscribe@lists.xxxxxxxxxxxxxxxx.dexxxxxxxxxxx-unsubscribe@xxx xxxxxxxxxx.de The last line in the left part contains 48 chars. I solved the problem by adding a whitespace in the last line and I made a new postmap for postfix_vmap. But it would be better to solve the problem by changing the genaliases process in the next update. Regards Wolfgang

Re: cc'd e-mail addresses rewritten with @invalid.domain
by Williams, Peter B Sept. 23, 2020

Sept. 23, 2020

Hi Mark, Thanks for the help with this! Other list members will also see the e-mail as coming from user(a)invalid.domain<mailto:user@invalid.domain>. I will continue testing the other scenarios and will reply back as soon as possible. Thanks again for the help with this and have a nice day!

For example in the scenario above my e-mail that is cc'd is also a member of listserv(a)lists.test.org<mailto:listserv@lists.test.org>. In this case, where do you see this? i.e., do other list members see it in the message they receive from the list? I don't know why that would be. I'm certain that Mailman is not involved in this and the Williams(a)invalid.domain and Peter(a)invalid.domain addresses are in the Cc: as received by Mailman. > This issue does not occur if the user e-mail address is listed before the mailing list in the cc field. So for example, if the cc in the scenario above contained Williams, Peter; listserv(a)lists.test.org<mailto:listserv@lists.test.org>; it would route properly. Again, I think this is Outlook. What's in the Cc: of the mail that test_user(a)gmail.com<mailto:test_user@gmail.com> receives directly? What happens if you send mail in this way with To: test_user(a)gmail.com<mailto:test_user@gmail.com> cc: other_user(a)gmail.com<mailto:other_user@gmail.com>; Williams, Peter; Again, what's in the Cc: of the mail that test_user(a)gmail.com<mailto:test_user@gmail.com> and other_user(a)gmail.com<mailto:other_user@gmail.com> receive?

Mails are not archived at all -- how to check if Hyperkitty is running or not?
by Franklin Weng Sept. 23, 2020

Sept. 23, 2020

Hi, I set up the mailman3 services and lists, and we can send mail to the list successfully. However in the Archive section I couldn't see anything and all the lists were "inactive" and hence were hidden by default. I confirmed that api_key set in the /etc/mailman3/mailman-hyperkitty.cfg and /etc/mailman3/mailman-web.py is the same. I also confirmed that the apache2 wsgi module has been loaded. In the mailman.cfg database is set to mysql and in the mailman-web.py database is set to sqlite3. Does it matter? I tried to search but couldn't find any further information or discussion about this. There is no systemd service for Hyperkitty. How can I check if Hyperkitty is running or not? Thanks, Franklin

API timeout for one list

Problem with list creation
by Pawel Grzywaczewski Sept. 22, 2020

Sept. 22, 2020

Hi, We want to create thousand of lists. We use a simple curl command curl --user restadmin:restpass -X POST http://localhost:8001/3.1/lists -d fqdn_listname=nameOfTheList(a)example.com After creating ~2k of them we started getting errors in Mailman logs: ``` [2020-09-16 17:11:10 +0200] [4564] [DEBUG] POST /3.1/lists [2020-09-16 17:11:41 +0200] [1339] [CRITICAL] WORKER TIMEOUT (pid:4564) [2020-09-16 17:11:41 +0200] [4564] [INFO] Worker exiting (pid: 4564) [2020-09-16 17:11:41 +0200] [5019] [INFO] Booting worker with pid: 5019 ``` Since then creation fails in most cases. We increased timeout in mailman.cfg ``` [gunicorn] workers: 4 timeout: 900 ``` And we increased timeout in nginx ``` http { # MODIF UNICORN proxy_connect_timeout 300s; proxy_read_timeout 300s; # MODIF UNICORN ``` Where might be the problem? How to start investigating and fix it? Thanks, Paweł

cc'd e-mail addresses rewritten with @invalid.domain
by peterbw＠gmail.com Sept. 22, 2020

Sept. 22, 2020

Hi, We've recently noticed an issue where users who are cc'd in a message where a mailing list is also within the cc list are getting rewritten a user(a)invalid.domain. This issue looks like it may be related to Outlook and how user names are displayed specifically. Here is an example: To: test_user(a)gmail.com cc: listserv(a)lists.test.org; Williams, Peter; "Williams, Peter" maps to a user e-mail in the Outlook Global Address book. When the message is sent the list will send the message with the first name and last name separated, for example the message will appear: to: test_user(a)gmail.com cc: listserv(a)lists.test.org, Williams(a)invalid.domain, Peter(a)invalid.domain This only seems to happen with users who are cc'd who are also members of the list that is being cc'd. For example in the scenario above my e-mail that is cc'd is also a member of listserv(a)lists.test.org. This issue does not occur if the user e-mail address is listed before the mailing list in the cc field. So for example, if the cc in the scenario above contained Williams, Peter; listserv(a)lists.test.org; it would route properly. Do you know what may be causing this? Please let me know if there is any additional information I may provide regarding this and I will try to respond as soon as possible. Thanks and have a nice day! Peter

Template path
by Seth Seeger Sept. 21, 2020

Sept. 21, 2020

Hello everyone, I’m running Mailman from Docker containers, without much customization. (Postorius 1.3.3, Core 3.3.1, API 3.1, Python 3.8.5). I’ve created a list:user:notice:welcome template, and when I try to confirm a subscription, I get an error. I followed previous emails on this list which told me to set POSTORIUS_TEMPLATE_BASE_URL in /opt/mailman/web/settings_local.py, but that doesn’t seem to make any difference. (I set it to a different value and the error message didn’t change. I also tried setting it in /opt/mailman/core/settings_local.py to no effect. After each change, I restarted mailman-web and mailman-core containers.) From within mailman-web and mailman-core containers, I can reach “mailman-web:8000”. In the webpage, I see: Mailman REST API not available. Please start Mailman core. In /opt/mailman/core/var/logs/mailman.log, I get: [17/Sep/2020:16:23:29 +0000] "GET /3.1/lists/xxx.example.com HTTP/1.1" 200 416 "-" "GNU Mailman REST client v3.3.1" Sep 17 16:23:35 2020 (48) deque: Traceback (most recent call last): File "/usr/lib/python3.8/site-packages/urllib3/connectionpool.py", line 426, in _make_request six.raise_from(e, None) File "<string>", line 3, in raise_from File "/usr/lib/python3.8/site-packages/urllib3/connectionpool.py", line 421, in _make_request httplib_response = conn.getresponse() File "/usr/lib/python3.8/http/client.py", line 1347, in getresponse response.begin() File "/usr/lib/python3.8/http/client.py", line 307, in begin version, status, reason = self._read_status() File "/usr/lib/python3.8/http/client.py", line 268, in _read_status line = str(self.fp.readline(_MAXLINE + 1), "iso-8859-1") File "/usr/lib/python3.8/socket.py", line 669, in readinto return self._sock.recv_into(b) socket.timeout: timed out During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3.8/site-packages/requests/adapters.py", line 439, in send resp = conn.urlopen( File "/usr/lib/python3.8/site-packages/urllib3/connectionpool.py", line 724, in urlopen retries = retries.increment( File "/usr/lib/python3.8/site-packages/urllib3/util/retry.py", line 403, in increment raise six.reraise(type(error), error, _stacktrace) File "/usr/lib/python3.8/site-packages/urllib3/packages/six.py", line 735, in reraise raise value File "/usr/lib/python3.8/site-packages/urllib3/connectionpool.py", line 670, in urlopen httplib_response = self._make_request( File "/usr/lib/python3.8/site-packages/urllib3/connectionpool.py", line 428, in _make_request self._raise_timeout(err=e, url=url, timeout_value=read_timeout) File "/usr/lib/python3.8/site-packages/urllib3/connectionpool.py", line 335, in _raise_timeout raise ReadTimeoutError( urllib3.exceptions.ReadTimeoutError: HTTPConnectionPool(host='mailman-web', port=8000): Read timed out.

Redundant and load balanced Mailman3
by Pawel Grzywaczewski Sept. 20, 2020

Sept. 20, 2020

Hi, Can someone share some hints about how to deploy redundant and load balanced Mailman3? What are your recommendations and best practices? For example what components to put on the same VM? Can we have 2VM with Mailman core/Postorious/Hyperkitty/django-mailman/mailmanclient connecting to one (the same) database? How to load balance mail routing (incoming)? Thanks! Paweł
