Ah. This is one of those areas I haven't quite got down: How do I

That gives me:
inetd 243 root 11u IPv4 477720 TCP *:smtp (LISTEN)
What program/daemon is listening?
I believe that this means that inetd is listening. I'm no guru, so those
that know better, please correct me, but I believe that inetd monitors
the ports specified in its configuration file (/etc/inetd.conf) and,
using the same config file, depending on the port, and type of
connection, starts whatever program is also specified in that file to
my /etc/inetd.conf file has the following line which tells inetd how to
handle smtp connections (the service names on the left are mapped to the
correct port using the /etc/services file, i believe).
#:MAIL: Mail, news and uucp services.
smtp stream tcp nowait mail /usr/sbin/exim exim -bs
Thanks so much! my /etc/inetd.conf has the same line. I'll see how far
I can get from there.
