I don't get any log entries for incoming emails, it seems like it never even gets beyond initail handshake attempts. I'm not currently using tcp-wrappers or iptables, and I don't currently have any anti-spam daemons running.
The only entries in my maillog are for local mail delivery and outbound mail. I did see one entry about certificates that may be a clue, from when I stopped and restarted the daemon. Mar 28 13:35:33 <hostname> sendmail[16898]: STARTTLS: ServerCertFile missing
I think you're correct, Redhat / Fedora RPMS are buit with tcp-wrappers support. I already checked my hosts.allow and hosts.deny, both are empty. I've never used tcp-wrappers with sendmail support, I last used wrappers a few years ago for basic telnet, finger, ftp etc support.
In the hope of it helping, I added sendmail: ALL all: 127.0.0.1 192.168.1.0/255.255.255.0
to my hosts.allow. As I'm less familiar with this use of wrappers, I assumed that you menat 192.168.1.0, not .9.0. Does it matter that all: on the second line is lowercase?

I did try changing it to 0.0.0.0 to see if that made any difference, but it didn't. Any suggestions are welcome, even if it may be somewhat redundant, and at this stage, I'll try anything so I appreciate the attempts to help anyway. I've tried all the suggestions Alexander made, and emailed him some more info. Once I get this fixed I'll post the solution in the hope that it may help anyone else who comes searching the archives later.
What does /var/log/maillog show for inbound e-mails?
BTW: If sendmail is compiled with tcpwrappers (and I think the redhat supplied sendmail rpm is)... and you have ALL: ALL in /etc/hosts.deny, then make sure you add:
sendmail: ALL all: 127.0.0.1 192.168.9.0/255.255.255.0
to /etc/hosts.allow
