1) I can "telnet localhost 25" on system "A" and that works (gets through
to sendmail just fine).
2) If instead I used the command "telnet A 25", I get the following: "telnet: connect to address xxx.xxx.xxx.xxx: Connection refused"
3) I get the same "Connection refused" message when trying to telnet
to port 25 on system A from any other system on the LAN (as I guess
I would expect).
These are all normal, and to be expected with a _DEFAULT_ (Red Hat) sendmail installation.
6) Since sendmail isn't listed amongst the xinetd daemons, that's not where it is enabled/disabled...
So what am I missing here???
You're missing the fact that a default RPM installation of sendmail only listens on localhost, nothing else. You need to remove, or comment out the localhost restrictions from sendmail.mc, and rebuild the cf file.
Sendmail (and a whole lot of other daemons) no longer use xinetd. Try 'chkconfig --list' and you'll see a bunch of stuff listed and what levels they come on or go off. That should help you a great deal.
