I'm talking exactly about "real", S/MIME digital signing of the message contents. As I have already mentioned, I routinely receive S/MIME digitally signed messages from companies that have actual reasons to write to me, like my bank, my phone operator, my ISP etc. Messages from them (for example informing about monthly bills etc.) are always digitally signed. Of course, there's no need to digitally sign a marketing message, because there's no critical information in it, that needs to be authenticated and verified. It's just blah-blah-blah. There's no need to use BIMI as well, other than purely marketing purposes, as I already wrote - to push the company's logo before recipient's eyes even if he/she decides to delete the message right away and don't open it. That's the real purpose of BIMI - "even if recipient decides not to read our message, let's force him/her to see our logo at least". It has nothing to do with protection against anything. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
