Under unix, lsv_amin is a "bridge" program that is called by sendmail, via an entry in /etc/aliases, for each individual inbound mail piece. That makes it possible to pipe mail for LISTSERV to the lsv_amin program. Under Windows, lsv_amin isn't used. The SMTPL.EXE "listener" service performs both the inbound mail function and the "bridge" to LISTSERV all in one package, and it runs in the background as a service. You can't pipe mail to SMTPL.EXE, so you're typically left with using Blat (or a similar SMTP file sending program) to send the mail via SMTP.
