This is an attack mail bombing the user. The requests that result in the can come via web or email. Mailman's logging of subscribes has been missing most events through Mailman 3.3.10. See https://gitlab.com/mailman/mailman/-/issues/1143 which will be fixed in 3.3.11, but subscribes waiting user confirmation still won't be logged. However, the message with subject "Please Confirm Your Email Address" comes from Django allauth so it isn't actually Mailman sending it but rather Django allauth as a result of a request to sign up for a Django account at https://mail.example3.com/accounts/signup/. You can probably find that request in your web server logs, and you may find the user and/or email in the Django admin UI. Since django-mailman3 1.3.6, you can disable these signups by putting ACCOUNT_ADAPTER = 'django_mailman3.views.user_adapter.DisableSignupAdapter' in your Django settings, but then your users won't be able to sign up for web accounts. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

Actually, this occurs after the message has been converted to an email.message with policy=policy.default. Getting the Message-ID attempts to parse it and in this case, the dot_atom_text it's looking for is the 'local part' which doesn't exist.

HyperKitty's contrib/check_hk_import script didn't find this issue. The GitLab branch was updated yesterday, but that update is not yet released.

Maybe existing users and user rights. Dumping the databases from the old serverr and loading them on the new server should work.

This all looks like Mailman's receiving of the message via LMTP from Postfix. This is inconsistent with Postfix reporting Recipient address rejected: User unknown in virtual alias table which would have occurred before any attempt to relay the message via LMTP. In order to understand more about this, I'd need to see at least the output from `postconf -n`. I'm just guessing here, but https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.h… may be applicable in your case. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

How can I set up Hyperkitty to > behave more like the lists.mailman3.org archives where replies to topics > are filed under their respective threads? HyperKitty's threading is based solely on In-Reply-To: headers. It does not attempt to thread based on References: or Subject: matching. Usually this works, but it can fail if for example A posts to a list. B replies off list to A and A replies on list to B's off list reply. In this case, the In-Reply-To: of A's reply is the Message-ID: of B's reply which isn't on the archive, so A's reply starts a new thread, but this is unusual, and HyperKitty has a "Reattach this thread" feature that a list owner or superuser can use to attach one thread to another. However, if this non-threading occurs regularly, It may be that the replyer's MUA is not setting In-Reply-To:. I've seen some phone clients do this. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B. Dylan

I don't have much to add to what Steve has said except our recommended config includes transport_maps = hash:/path-to-mailman/var/data/postfix_lmtp in Postfix main.cf. This should contain (per your log message) things like ListName-confirm(a)ListServer.TLD lmtp:[127.0.0.1]:8024 to tell Postfix to deliver that address via lmtp to port 8024 on the local host. Dovecot should not be involved. There is something in your config that trumps this and delivers via lmtp to Dovecot for mailman3:[127.0.0.1]:8024. Does your transport_maps look like the above or perhaps like ListName-confirm(a)ListServer.TLD mailman3:[127.0.0.1]:8024 If so, I don't know where mailman3 instead of lmtp: comes from. Also, even if it is lmtp: I don't know that Dovecot can deliver via lmtp. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

This has nothing to do with whatever WSGI server (uWSGI, Gunicorn, Apache mod_wsgi, ...) is used to support the Django applications (django-mailman3, hyperkitty and postorius). I.e., there is always a Gunicorn instance configured and started by Mailman core, regardless of whatever WSGI server supports Django or even if one isn't running Django at all. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

The content is stored in the mailmanweb.postorius_emailtemplate table. As far as Mailman core and Postorius are concerned, that's the only place. I'm guessing, but my guess is it's cached in your wsgi server. I.e., upon initial creation an entry is made in the mailman.template table with a uri like https://example.com/mailman3/api/templates/list/list.example.com/list:user:… and when Mailman core wants the template, it gets that uri which I'm guessing is then cached in the wsgi server. Then, if the content is changed, the GET returns the old cached value instead of getting the new value from Postorius. If the template is deleted, the mailman.template table entry is deleted and at that point Mailman core will get the template from the file system following it's normal search rules, but if the template is recreated in Postorius, a new table entry is made with the same uri which may still get a cached template from the wsgi server. If this is correct, restarting mailman-web or whatever controls the wsgi server should fix it. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
