Ok, cool
I think my solution is to post a stub of a topic outlining the content. I let it get emailed / included in digests, then I’ll go back and adding in all the details that I don’t want emailed out.
In this case, it’s a list of malware, so the emails would get trapped in spam filters.. I don’t care if the people see the message, but if it were emailed, it’d hurt our sender reputation.
