Hello Eric, on the large lists issue I have been reading the Site Managers manual and I noticed there is an option called SMTP_FORWARD that apperas to use another machine to deliver all mail for Listserv. If this is the case can all mail from lsv.xxx.org (where listserv is running) be forwarded to lsmtp.xxx.org for delievery (an NT box running LSMTP)? Are there any disadvantages/problems with this setup? Regards, David
