In the event memory is needed, sendmail will be paged out or swapped out as the OS determines necessary. There is no "savings" from your change if you have swap space defined.
In addition, you have shown yourself concerned about security. Shutting down sendmail prevents you from seeing the results of security(8) output, which security-conscious admins should be reading every day.

I have also disabled the service ssh!

You were asked during install if you wanted sshd(8) to be started. Had you replied "No" sshd would not be enabled in /etc/rc.conf.local.
