These should be the updates from the last two days or so. (except John's s/malicious//, already altered for next run) I found a few more places where the mmark/xml2rfc process was creating some improper output, I believe all for the "_report._dmarc" bits. -- Alex Brotman Sr. Engineer,

There is no universal definition of private data, so I don't think we should make universal claims about there being no private data involved. It's true that some concerns might be assuaged by such an assurance, but I don't think that's a good reason to do it as I don't think the statement is

Assuming for a moment that single user domains can't have a privacy violation (I'm not sure I agree), how about a two person domain? Three? Unless it's impossible to have a report that contains personal information, mail receivers (report senders) absolutely can't rely on the assertion in

John is not alone, I too can recognize single posts. However, I'd argue that in such cases there is no privacy violation. You violate privacy when you collect personal data of (several) people *different from yourself*. Best Ale On Tue 25/Apr/2023 18:36:34 +0200 Scott Kitterman wrote: My

My suggestion is delete all of it. It's accurate for some cases, not for others. If you want to keep any of it, I think it needs to be properly caveated. I expect that would be a Sisyphean task that's not worth the effort. Scott K On April 25, 2023 2:54:46 PM UTC, "Brotman, Alex" wrote:
