Interesting you should mention that, given that I just watched a video [1] discussing some of the ZIP format's pitfalls and oddities. [1] https://youtu.be/RYHYiXMJdZI Since archives may potentially even start with random data, I wonder how reliable the suggested sniffing is? If the sender of a DMARC report fails to provide correct content type information, which should be simple enough, how trustworthy are the archives themselves? -Ralph _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
