Try if the command your_machine% telnet your_machine 25 works. It should connect you to the smtp daemon. If you get a message "connection refused", you don't have a (inet) daemon running on port 25. >Which process in the SCO system is supposed to be monitoring this port, >and how do we get it started up? This is the Berkeley Internet Daemon. The inet daemon (/etc/inetd) listens to the port. When a connection is setup, inetd searches for a free socket and starts the local smtp daemon on that port. Your inetd configuration file (/etc/inetd.conf) should have a line like: "smtp stream tcp nowait mmdf /usr/mmdf/chans/smtpd smtpd /usr/mmdf/chans/smtpsrvr smtp" (this is ONE line!). -- Ronald van der Pol
