Here is the page that under a minute of googling helped me find: https://lists.debian.org/debian-security/
To unsubscribe, enter your e-mail and click the 'unsubscribe' button. That didn't work? Maybe try taking the advice here: https://www.debian.org/MailingLists/#subglitches Short of spamming the entire mailing list (to which, making a conservative estimate, at least a few hundred people subscribe), you might want to try mailing the hostmaster if you can't figure out how to either unsub or make a gmail filter rule. "someone take my email off the list or I will report it as harassment." I know this is probably frustrating for you, but lay off the legal threats. For one thing, if you actually *did* follow through that almost certainly wouldn't go anywhere, but more to the point threatening people makes them less inclined to want to help you. "Unsubscribe me or I will spam your list" For a number of reasons, that would not be a good idea. One being that it's almost certainly a violation of Google's ToS, and this would be a very silly thing to get banned over. And no, I am in no way affiliated with the Debian project. -- "If you give me six lines written by the hand of the most honest of men, I will find something in them which will hang him." - Cardinal Richelieu
