Is it possible to block emails containing QR CODE?
Whilst we might like a SafeLinks facility that translates a QR code into a URL that is subject to the usual URL detonation tests (or even better, a header that we can hold our own council on) we will quite happily settle for a header that says "X-QR-code detected: true".
And when detecting that code, please don't assume black-on-white or some other two-tone color pairs; I already have psychedelic ripple-contrast codes dancing through my head; if the camera can read it, attackers will use it. I must have seen too many of the damnable things already.

ExMSW4319Agreed - at a basic level we need to know if a message contains a QR code or not. Detecting URLs, safelinks translation, etc would be nice to have. Detecting if a QR code exists or not is essential.
Fancy look codes gets much more crazy than just psychedelic colors - look up what people are doing with stable diffusion and QR codes. The good thing is, the whole point of QR codes is to be easily detectable. So, standard detection algorithms should do a pretty good job and keep compute resource requirements relatively low.
