There was a "security" reason for the change. Since local email is essential, for example for reporting the results of the "daily" scripts run out of crontab, you should either reenable your sendmail daemon on port 25 or reconfigure your local email to not route everything through the daemon. There are instructions for doing this somewhere in the sendmail documentation. I think it involves hacking /etc/mail/submit.cf. Note: the sendmail binary that comes with FreeBSD was built with libwrap.a support. That means it obeys /etc/hosts.allow and can be told to reject all non-local connections to port 25.
