Some/many people use DKIM signatures when posting to our lists, with or
without their knowledge. Once we have received a message, we make some
modifications - change Subject, append text, remove headers, which
invalidates the signature, potentially causing a reject.
I was wondering if anyone had any thoughts on $SUBJ ? as far as I can
see, it could potentially improve on the current situation, although I
have not heard of many problems. I suspect most mail admins are well
aware of the issue with mailing lists and DKIM, DMARC et al.
As an experiment, I have already implemented $SUBJ for a couple of our
lists, opensuse, opensuse-support and opensuse-factory.
