The &WHO and $INVOKER do not appear to be defined for the TOP_BANNER and BOTTOM_BANNER. I have not tried $MBX alone, but since &WHO/&INVOKER are not defined, when paired with them it returns nothing. A subscriber has pointed out that the mail originator ("real" from:) is not identifiable when the message is received (a problem with some of the receivers' mail packages, not listserv). Is it possible to embed, as a minimum the sender's email address and better, the "name" from the signup file in the TOP_BANNER or by other means in the body. running: listerv 1.8b under VM/CMS ESA Second question: When listserv sends mail to multiple addresses at a single node (through internet, not bitnet) does it send multiple messages or a single message with multiple recipients. Have some bouncing mail with no listing of who the problem id is and can't see it in the attached problem message. Thanks.
