For background, there's typically a time in the summer where many user accounts are purposely disabled (generally near July-August, I think). From the bounce file dates, I wonder if this bounce-related issue has been happening for longer than I first realized. The issue is that sometimes the bounce runner dies. This can be from an OOM error or some other reason, but I have observed it even on systems I admin. The master SHOULD restart it, but it doesn't. See https://gitlab.com/mailman/mailman/-/issues/898. Anyway, it appears your bounce runner died sometime on or before June 7 (if you have syslog from then it might have a clue), and you didn't stop and start Mailman core until August 4 when the bounce runner started again and began chugging through it's queue. I.e., I think everything in your installation is OK and the excessive load was just due to processing the 34775 queued bounces that should have been processed gradually over the previous 2 months. Although 500 bounces per day seems like a lot, but if you have a lot of lists, and bouncing users aren't being disabled because bounce runner isn't running, this may be normal. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[MM3-users] Re: Mailman rewrite the Cc header incorrectly

I have started to work on this, but I have run into a snag. The patch at <https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message…> doesn't work. The problem is msg.get_all(header, []) does not parse the header and return a list of addresses. It just returns a list, the items of which are the raw values if the header instances in msg. I.e., if there is only one Cc: header, msg.get_all('cc', []) returns a list of one string which is the raw value of that header. If there were two Cc: headers in the message it would return a list of two strings with the two raw values. Thus, we would need to parse the strings returned into the individual email addresses. The simple minded way to do that is addrs = [] for hdr in msg.get_all(header, []): for addr in hdr.split(','): addrs.append(parseaddr(re.sub('[\r\n]', '', addr))) but that will fail if the header contains a quoted display name containing a comma such as "last, first" <user(a)example.com> So, I need to go back to using getaddresses, but do the unfolding first. Watch the issue for the final fix. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B. Dylan

With the settings you have the mother list puts the original From: in Reply-To: and it's own address in From:. Then regardless of what the daughter does with the incoming Reply-To:, it will add the incoming From: to Reply-To: so the Reply-To: of a message from the daughter will always contain the address of the mother. The best you can do, unless you are willing to set DMARC mitigation action: to No DMARC mitigations is what you started with which is First strip reply to: No on the daughter which will at least put the original From: to the mother in Reply-To: from the daughter along with the mother's address, but you can't remove the mother's address from the daughter's Reply-To: because DMARC mitigation will always put it there. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

This is not the case in MM 3. It probably should be, but isn't. Senders are or aren't notified per "Notify users of held messages".

Do you even have an MTA listening on localhost, port 25? You need to figure out what settings you need to be able to connect to your outgoing MTA and set EMAIL_HOST EMAIL_PORT and maybe some of EMAIL_HOST_USER EMAIL_HOST_PASSWORD EMAIL_USE_TLS EMAIL_USE_SSL EMAIL_SSL_CERTFILE EMAIL_SSL_KEYFILE appropriately so you can connect to the MTA. If outgoing mail from Mailman works, look in the [mta] section in mailman.cfg for the appropriate settings. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

That should be followed by a GET like "GET /3.1/domains/domain.tld HTTP/1.1" where domain.tld is a configured domain. Do you have any domains configured?/0.9'? I'm not sure what the issue is. You have an older version of mailmanclient < 3.2.3a1 which uses httplib2 rather than requests. https://pypi.org/project/httplib2/ says: HTTP and HTTPS HTTPS support is only available if the socket module was compiled with SSL support. but I don't think this can be the issue because the first 3 GETs work. You might try upgrading mailmanclient to 3.3.0.

One of the runners has died, most likely the `out` runner, but possibly another. The missing messages are stuck in a queue. Do ``` ls -laR /opt/mailman/core/var/queue ``` to see in which queue the messages are. The runner that processes that queue is gone or possibly stuck. Do ``` ps -fwwu mailman|grep runner= ``` when things are working to get a list of what runners should be there. Do it again when things aren't working to see what's missing. There also should be something in mailman.log about why the runner died, but if it was killed for some external reason, there may not be anything. Look in `syslog` for something like an out of memory (OOM) or other issue that caused the runner to die. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

Now it's my turn to apologize. I've been traveling. In your original post you wrote "I've tried removing it and reimporting it to no avail." What exactly does this mean. You removed the list how? Then you reran the import21. Was the list broken at that point, or only after removing the old owners and adding yourself? What if you try the following steps in order and try to view the list in Postorius after each step. - remove the list with `mailman remove list(a)example.com` and recreate it with `mailman create list(a)example.com` - run `mailman import21 list(a)example.com path/to/config.pck` - in Postorius, add yourself as owner. - in Postorius, delete one of the other owners. - repeat the deletion and viewing the list for the other unwanted owners one at a time.
