There should already be an example in /etc/mail/freebsd.mc (no
linewrap):

dnl FEATURE(dnsbl, `blackholes.mail-abuse.org', `"550 Mail from " $&{client_addr} " rejected, see http://mail-abuse.org/cgi-bin/lookup?" $&{client_addr}')

Change the relevant information to use DNSBLs.  For example, here's the
one I use for the excellent XBL-SBL list:

FEATURE(`dnsbl', `sbl-xbl.spamhaus.org', `"554 Mail from " $&{client_addr} " rejected, site listed on http://www.spamhaus.org"')
