Well, there ya go. There is no restriction that would prevent that
message from being delivered, so of course they get through.
At a very minimum, please add: 'reject_rbl_client zen.spamhaus.org' to
smtpd_recipient_restrictions. That'll stop quite a few of them as well
as a lot of other junk.
As far as SASL support, you can verify with postconf -a. Making postfix
aware of Cyrus or Dovecot is another thing that probably should be done
at some point.
See http://www.postfix.org/SASL_README.html#build_postfix or check with
your distribution/vendor for support if postfix was supplied to you in a
package.
