I had one just this morning from a person who says he can't get LISTSERV to respond to him <and> when he posts to the list it always says "From: Unknown Origin". Looking at his message to me I could see why: it didn't have a From: line. So either his mail program is hosed or his ISP's mailer is stripping the From: line. This might be what's causing your user's problem. BTW the list in question has ",Confirm" set so this is clearly a problem that has cropped up <since> he subscribed. Anyway you should check the headers of mail that he sends you for any abnormalities. >I get this from people all the time. I also get messages that they have >been confirmed (and are getting messages) and then still get this >failure message. I also am told about signing off (and receiving >confirmation of getting off) only to keeo receiving messages. When I >check, they are still there. > >I've always put it down to user error. If someone knows differently, I'd >appreciate knowing about it.
