Note that a significant percentage of reports come from external people (not list members), and a significant percentage of them are reporting an issue to one of these lists for the very first time. This is a reason why they may miss list policies stated on the wiki. They'd similarly miss "an agreed upon way to take disclosure dates", and it'd be a job probably for a human to notice and explain this to them. Well, maybe we could have a script notice the start of a new thread and the lack of a properly formatted proposed disclosure date in the first message, and that script would send e-mails complaining about that. > It is then simple to have a script that (1) > complains when (disclosure date - thread creation date) > max embargo > period (2) complains when a disclosure date has been exceeded without an > indication that there has been a public statement. To detect case #2, it'd need access to archived messages.

OK, a list member could run that script, entering their key passphrase once in a while (such as to read new mail and also to run the checks). I don't mind you giving this approach a try. Whatever helps you get the job done while not putting the sensitive info at too high a risk. > I would propose we use a system like: > > X-Disclosure-Date: 2014-06-01 > > To set/update the disclosure date for a given thread.

And someone (also a script?) should check that a posting to oss-security (on that very issue) has in fact been made (match by CVE ID mention, assuming there was one assigned? but sometimes there won't be, e.g. in case an issue is determined to be non-security, yet per policy needs to be brought to oss-security anyway). It gets tricky, I think to the point where doing it semi-manually is better. We're not processing a huge number of issues. Tracking the currently open issues e.g. via a tiny text file is viable. Someone just needs to do it consistently. > I can watch threads for now and make sure metadata is getting tagged but > hopefully over time all list members will participate making it not > depend on one person.

I suggest that you start by doing the job yourself, whether manually or with help of scripts you might write. As to all list members participating, I think this is overkill and it won't work reliably, just like it has been occasionally failing so far (when it's everyone's responsibility, it's also no one's). I want a specific person (or two, but not many) responsible for this. We can (and should) ask others to follow list policies, but this doesn't eliminate the need for some of us to ensure that policies are followed. Thanks, Alexander P.S. BTW, I think it's in fact better if you post from your personal address, because when you post from your Amazon address your envelope-from keeps changing, preventing whitelisting. And there's the DKIM issue you mentioned.
