update on cox webmail filtering
something has changed.
I spent months creating filters that would whitelist (still works) known good email addresses, and reject bad email with reason "553: account doesn't exist". It used to work.
I also spent months marking all spam going to my spam folder as not spam.
so now the stuff I finally got to stop going to my spam folder has suddenly begun showing up in my inbox regardless of my filter to reject it. I did some testing this morning and confirmed that "reject with reason" and "discard" do nothing.
the best result I can get is to have bad email marked as "seen" and routed to the trash.
in 25 years of IT I have never had to deal with such terrible filtering or service.
