I'll chime in with some quick observations (I run sendmail 8.13.8 on
Solaris 9).  

The two first places I'd look are:

1.  The tcp-ip services file (/etc/inet/services on Solaris) needs a
line that says:
smtp     25/tcp      mail

2.  There needs to be a sendmail -bd daemon running.  That is the one
that listens for incoming smtp. 

I don't see anything specific to port 25 in the .cf files.  

I would also check any router/firewall between your sendmail client
machine to make sure that incoming port 25 traffic is not being
blocked; also any ipfilter setup.
