I don't think this is a problem. GPG or S/MIME signing with any software I know of only signs the message body (or a MIME part). DKIM message signing isn't going to care about the order of fields because DKIM canonicalizes the order (at least for the unique fields) according to the specification in the signature field, and that will be verified on the way in. Of course adding a Message-ID will likely break DKIM for the outgoing post, but Mailman as normally used breaks DKIM anyway. This can be partly mitigated by using ARC (authenticated received chain), which is supported by Google already, and possibly some of the other usual DMARC suspects (Yahoo!, AOL). > > Probably the more correct way to do it is only add a new header if it's > > missing, and if it's there, leave it alone. True, and I think this does it: headers_add = ${if def:h_message-id:{fail}{Message-ID: ... id generator code ...}} If you like that and test it, I would really appreciate feedback so we can update the documentation. One thing *I* would like to add to this recipe is logging. I'd be curious to see how frequently it happens outside of spam and junior high school hackers using netcat as their MUA. I don't see how to do this in Exim, though. Another is using a prefix other than "E" to indicate this isn't standard Exim behavior. Steve

No such users in the Django UI, but the web server logs have 252 attempts from 132 unique IPv4 addresses registered to different ISPs throughout Europe. So, even though Mailman support for more detailed logging of sub and unsub requests would be useful, it likely would not have helped with attacks from many source IP addresses. > > 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. I have made this change. As for not having web accounts, this just means new users cannot sign up to manage their Mailman settings, correct? I presume existing web accounts will continue to work.

by Allan Hansen

Thank you, Mark. By "However, all of the above can be avoided without any DMARC changes by enabling bounce probes." Do you mean that I can get rid of the 'From' mangling, which has been a frequent source of embarrassment because the list address is captured and reused by type-ahead when sending non-list messages and those messages instead going to 1000 subscribers. __ Allan On 2/1/23, 09:59, "Mark Sapiro" <mark(a)msapiro.net> wrote: On 1/31/23 22:32, Allan Hansen wrote: > Hi all, > > Apparently Google just started to get very aggressive about DKIM settings.

Will enabling them without the bounce score being reset just cause the server to disable them again. Yes, Google has started enforcing a policy which is effectively DMARC p=reject even for senders whose domains don't publish DMARC p=reject or quarantine. To avoid this issue, you may need to set DMARC Mitigate unconditionally to Yes as well as DMARC mitigation action to Replace From: with list address if it isn't already. As far as enabling without resetting the bounce score is concerned, I think you are correct that they will just be disabled again on the next bounce. This is a bug and should be fixed. However, all of the above can be avoided without any DMARC changes by enabling bounce probes. in the [mta] section of mailman.cfg, set ``` verp_probes: yes ``` Since the probe is sent From: the list's domain, it should pass googles SPF and DKIM checks and not bounce. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

Hello, Please pardon a slightly off-topic comment, but I would like to highlight a part of Odhiambo's post. Heavily nested inline replies also reflect the issue I wish to comment on, so I'm not going to. Granted, I am a slow learner, and perhaps already so mixed up after reading > the myriad HOWTOs for > installing MM3 that are available online. I am tempted to say there are > many like me who are likely to > miss "where to obtain" other settings from. and > Is it possible to modify the documentation to somehow make it obvious (in a > language that a layman can easily understand, I have seen this with several open source projects lately. There's no big picture, just 'hundreds' of cross-linked little bits of disjointed information that almost seem like documentation for individual modules. I once joined a large commercial project for a major US computer company (sorry, I won't share details). They were quite proud of their extensive documentation. The docs for their equivalent of the kernel syscall interface, when printed (two-sided) and stacked, would easily approach 2 meters tall. Yet, every bit of it was incomprehensible unless and until you called the developer and had them explain it to you. The problem that we all have, us humans, is that when we are very familiar with something, like the code we've been working on, it is very hard to describe its purpose to somebody who knows nothing about it. ("It's obvious to me, so it should be obvious to you."). So, a challenge for us all: When writing and reviewing your documentation, imagine that you're explaining your whole project face-to-face to your grandmother, or to anybody who never learned to program. From experience I promise that it's easy once you get the hang of it.
