Due to the huge number of variants in the wild, our AV software can't

antivirus, abuse, security, etc. which don't originate from our
management IP space where our people work. As a result, we have stopped
these phishing scams for our users dead in their tracks.

We did as well, but we did not yet find a solution for legit bounces..
it naturally breaks that.

It's a temporary solution to what I see that is going to become very big.

The bigger issue is that users simply don't trust any kind of "official communication" anymore and I don't see anything other than pki that could actually restore that.
