I operate my own mail server. I followed the great instructions in "Run your own mail server" by @mwl
Last night I had the idea, that it would be nice to publish a public key for S/MIME in my #DNS like the stuff for #DKIM, #DMARC and #DANE. I would really like to automatically get #encrypted emails by other people.
Turns out, this idea isn't new, but #RFC8162 from 2017 is marked experimental.
Any news on this?
Please boost. I really would like new information about this.
@jeremiah_ @elb #NNCPNET, the new #NNCP-based email network, now has a bidirectional, opt-in, Internet #email bridge! https://salsa.debian.org/jgoerzen/docker-nncpnet-mailnode/-/wikis/bridge/intro
This gates Internet email to/from NNCP. The bridge is off by default. It is a full participant in #SPF, #DKIM, #DMARC, and #TLS in both directions.
Yes, now you can get Internet email straight to your #RaspberryPi ! (And even without this, your Pis can email each other!)

Week 8, The Simple Mail Transfer Protocol, Part III
In this video, we look at ways to combat Spam. In the process, we learn about email headers, the Sender Policy Framework (#SPF), DomainKeys Identified Mail (#DKIM), and Domain-based Message Authentication, Reporting and Conformance (#DMARC). #SMTP doesn't seem quite so simple any more...
Has anyone here on #fedi figured out the correct recipe for dealing with #OpenPGP, #DMARC and #mailman ?
The problem, by default mailman will modify messages and this will break the dkim signature.

Mailman provides two DMARC mitigation options (other option is reject or discard which is not useful in this case).
1. Replace the from address with list address
2. Wrap original message in an envelope
thunderbird flags 1 and fails 2.
