I received the following mail rejection message from a gateway in the
 UK and wanted to warn other Listserv maintainers.  It seems that the
 gateway code constructs a mail header that Listserv doesn't recognize.
 Therefore the mail is sent to the list.  This could easily lead to a
 loop condition, but for some reason that didn't happen in this case.
 In any event, I've served off the gateway.
