You fix it in your sendmail configuration by telling sendmail to listen for port 25 connects from anywhere. I can't tell you how to do that because I don't know.
Perhaps you can read some sendmail documentation or ask on a sendmail list.
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:
The tcp-ip services file (/etc/inet/services on Solaris) needs a line that says: smtp 25/tcp mail
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.
