Marc Shannon forwared a note to the list that he had gotten from LISTSERV@CMUCCVMA about the fact that it had denied itself privledges after 10 botched commands or something. The note he forwarded looked like the mangled headers all of us later saw this afternoon (US time)- I'm not sure how, but I think someone's server got tangled up rather badly on the note. I do not know if Eric's work with RFC 822 is related or not- it does look like something did some transformations like Eric was describing, but that's not definitive. (I do not mean to imply that either Marc or Eric are to blame here; I am merely trying to come up with a plausible explanation for events without considering cause too deeply.) Nick
