This mailing list is not DKIM (DMARC) compatible

Gerben Wierda-2
The footer that is added to each message in this list is not DKIM (and thus DMARC) compatible. DKIM requires the ability to create a signature on a set of headers and the body. By changing the body, the DKIM signature fails and the resulting messages sent by the mail list may in the future be blocked by  more and more mail servers.

Maybe it is a good idea to make the list DMARC-compatible.

In addition: Lists should keep the From address, the Subject, and the Message totally unchanged. They should add a Sender header to indicate their relay role, and set at least the List-Id and List-Unsubscribe headers for mailbox rules and subscription management.

Re: This mailing list is not DKIM (DMARC) compatible

I wonder if something like this is the reason why I’m no longer receiving my daily arXiv emails. They suddenly stopped coming after 7-9-2019, except for two sporadic ones that arrived on 8-30-2019 and 9-4-2019. arXiv customer service claims that they are sending them out. On my end, I’m still using my old Earthlink email address, and my emails are still managed by Earthlink email servers, but I’m connecting to the internet via an AT&T modem/router and the AT&T fiber backbone. Earthlink support claims that they are not blocking them as junk mail, and I even whitelisted the arXiv email address in my Earthlink account. But maybe they’re not being blocked as junk but for some other technical reason by Earthlink, or even by AT&T itself or their modem/router whose firmware gets updated automatically every once in a while. It’s been frustrating trying to diagnose this.

I just realized that this is the first message I’ve gotten from OS X TeX since 8-31-2019. Am I not getting some of these emails as well? Usually this list is a little more active than this.

Re: This mailing list is not DKIM (DMARC) compatible

Miller, Andrew J.
Hi All,

It does seem like there’s been a lull in the traffic, but I assure your our server is still waiting patiently for you to send your messages to the list. :-)

To address DMARC compatibility, I must confess that I am not very familiar with some of the more recent email standards so we hadn’t thought to configure our server to cope with them. I did a little research and contacted Karl Berry who runs the multitude of lists over at tug.org and his recommendation, to minimize the amount of pain to users, was to adjust the dmarc_moderation_action setting for the list, but otherwise to leave the subject prefix and footers alone. The List-Id, List-Subscribe, List-Unsubscribe headers and the like are all set already.

If you have a subscribed address that you think is not receiving email from our list, let me know which address and I’ll take a look at our log files.

List archives are here https://email.esm.psu.edu/pipermail/macosx-tex/ if you want to see if you missed anything.

Hope this helps.

Re: This mailing list is not DKIM (DMARC) compatible

Gerben Wierda-2
My guess is that if you leave the change of body in place, participants that are sending through mail servers that support SPF will fail (because of the resend by the list) and support for DKIM will fail (because of the changed body)

You will still receive the 'list-forwarded’ messages from senders who do not use DMARC, you will start missing those that do. It is unlikely that you will suddenly stop receiving all messages from the list (e.g. mine will go through as I haven’t yet turned DMARC fully on, but as soon as I do, I will be unable to send messages via this list to those at the receiving end that do DMARC checking, and that holds for more and more users.).

The sender’s email manager will also get unnecessary reports of the list server illegally sending messages on their behalf.

Most list these days that I am on already have removed the footer, and leave the Subject: line alone. Sorting can be done on other headers than Subject.

Using dmarc_moderation_action means that you start to munge headers etc, which is not optimal:

However this is a poor use of email, since it’s misrepresenting who originated the message. Also email clients often have a degraded interface with respect to the Reply-To header. It’s usually not visible in the message list, not used for sorting, and not added to the address book.

But whatever you guys do, make sure you are DMARC-proof to prevent running into these issues later on.
