This happens when people have their mail system misconfigured to send bounces to the header From: instead of the envelope FROM. If you receive them in the future, please forward them to listmas...@lists.debian.org with a brief explanation of which list you sent the mail to and when, and we'll unsubscribe (or try to unsubscribe) the offending address. [Debian mailing lists have bounce handlers which automatically deal with bounces which correctly go to the envelope FROM, but unfortunately there are an infinite number of ways to misconfigure e-mail servers.] -- Don Armstrong https://www.donarmstrong.com I'm So Meta, Even This Acronym -- xkcd http://xkcd.com/917/
