When you installed postfix via pkg, did you install postfix, or 
postfix-sasl?  The postfix port is flavoured:

$ pkg search -r FreeBSD -x 'postfix(-.+)?-3.7.2'
postfix-3.7.2_1,1              Secure alternative to widely-used Sendmail
postfix-ldap-3.7.2_1,1         Secure alternative to widely-used 
Sendmail (with OpenLDAP and Cyrus SASL support)
postfix-sasl-3.7.2_1,1         Secure alternative to widely-used 
Sendmail (with Cyrus SASL support)
