	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.

	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!).
