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…

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.
