Comment 6 for bug 1851804

Necropost here :)

I was not able to get running on RHEL8, I think due to 1.2.3 requiring pymilter 1.0.5, as this is not available (only 1.0.4 on RHEL8)

I *was* able to get it running simply on RHEL9:
- adduser --system --no-create-home --shell /bin/false --home /run/dkimpy-milter dkimpy-milter
- enable the codeready repo (command varies between RHEL and Centos)
- dnf install sendmail-milter-devel
- dnf install python3-pynacl python3-pymilter
- pip3 install -U pip setuptools
- pip3 install dkimpy-milter
- systemctl enable /usr/local/lib/systemd/system/dkimpy-milter.service
- systemctl start dkimpy-milter

Obviously need to configure the .conf file to suit.

Seems to work OK, just running in v mode for me at the moment.
