BSD Unixes have shipped with Sendmail for decades, much as BIND is also
included-- so yes, Sendmail is included with the base system by default.

The approved way is to simply leave things be.  Properly written software
will honor the links setup by mailwrapper(8) and use the Postfix MTA which
you installed instead:

If you really want to remove sendmail entirely, you can rebuild FreeBSD with

   NO_SENDMAIL=TRUE

...set in /etc/make.conf, which will avoid building sendmail at all.
