Problem solved I think - thanks again to Andreas's suggestion. I won't know how a mail program can be so stupid as to fling everything back to the list, but the evil miscreant has been removed and (hopefully if I got it right) blacklisted. Michele - you saw "too many hops", thank goodness, because mail programs set a maximum number of points on an email's journey before they decide not to pass it on - usually around 18. This is to stop just this sort of thing: Sinister mailing to a mentally disturbed mail program that sends it back to the list, that sends it back to the program... In fact if I hadn't been sleeping I would have noticed that the bounced messages contained multiple footers indicating just this. Incidentally it may come as no surprise that the site concerned was using a Microsoft mailer... Oh and if you're receiving this and thought you'd unsubscribed - can I remind you to send sun/unsub requests NOT to this address but to: majordomo@majordomo.net I will NOT in general have time to do unsubscribes manually - too much (real) work (eh?). And if you close your email account: please unsubscribe from Sinister before! I know it's hard to remember but... spare a thought for my aching mailbox! I still love you all and want to have your babies. P ----------------------------------------------------------------------- . This message was brought to you by the Sinister mailing list. .
