I have many accounts. One I use to collect notebooks and then ship them to another account. I then MAIL from that account. Hence on this account I am not signed up for LSTSRV-L but I am sending something to it. LISTSERV will not accept my SET NOACK from this account because I am not registered on this account (but am on another account). Soooooo, is there any way to get LISTSERV to 'shut-up' the ACKS about distribution when I am not registered on the particular list? Bob
