I have unsubbed the amazon.com address. Please let me know immediately if the problem occurs again, and I will then block amazon.com from the LyX lists. At this point I am just not sure if some people could have an email account at amazon.com.
The problem was--besides that amazon.com somehow got subscribed---that amazon does not bounce to the address it supposed to (the enevelope sender address) but to the address in the From: header. If amazon.com bounced properly, our list manager software, ezmlm, would have unsubbed it because of bounced messages. Mate
