                                 20 ; SERIAL
                                 7200 ; REFRESH
                                 600 ; RETRY
                                 3600000; EXPIRE
                                 60) ; MINIMUM

Note the use of the \ character in the SOA RR to specify the responsible
person mailbox "Action.domains@E.ISI.EDU".
