You don't need to remove the base system sendmail.  All you need to do
is set up /etc/mail/mailer.conf properly -- and installing the postfix
port should do that for you -- and then any reference to
/usr/sbin/sendmail, /usr/bin/mailq, usr/bin/hoststat etc. will run
postfix instead.  It's really very nicely done.

See mailer.conf(5)



PS. Alright, yes.  You can prevent sendmail from being built as part of
the base system by defining 'WITHOUT_SENDMAIL=yes' in /etc/src.conf, but
this supposes that you want to build the system yourself, rather than
using, say, freebsd-update(8).  See src.conf(5) and read in
/usr/src/UPDATING and the Handbook about the procedure for building the
system from source.
