It's sole purpose is to accept mail coming into the box and hand it over to LISTSERV. It cannot send mail. Im assuming you're using a Windows box which means you have two options: 1. Point LISTSERV to an external mailer. Your SMTP_FORWARD= entry in the config file should have an IP address or FQDN that is not the local machine. And make sure the external mailer is set up to accept and relay mail from LISTSERV. 2. Consider using L-Soft's LSMTP mail software on the LISTSERV machine as well. It's the only Windows SMTP software that actaully works correctly on the same box. (And don't even consider trying the SMTP service on a Win2k or XP box....I have and it creates more mess than dropping a dozen eggs out of the carton.) -- Chazzozz!!
