Yes, it is just that most emails I receive are sent through ISPs or from
commercial companies, and go through a bunch of internal relays.
Although completely standard, such direct emails are rare enough for me
that I noticed…
— There is a DKIM signature done by my own server (d=yalis.fr), which includes
the From header, and that header is @yalis.fr.
As Slavko said, check that the signature is actually valid. If it is, review
you exim config and see how they might have been able to get your exim to sign
the message. Maybe you have a flaw in your config?
If that is any help, my server is built using Ansible, and the whole
configuration is public:
https://yalis.fr/git/yves/home-server/src/branch/master/roles/dmz_exim/tasks/main.yml
Based on Archlinux packaging for Exim
(https://github.com/archlinux/svntogit-community/blob/packages/exim/trunk/PKGBUILD),
my exim.conf seems to be just upstream Exim 4.96 configuration. Then I
patch it using Ansible with various rules.
