NAME

       opendkim-genzone - DKIM public key zone file generation tool

SYNOPSIS

       opendkim-genzone  [-C address] [-d domain] [-D] [-E secs] [-N ns[,...]]
       [-o file] [-r secs] [-R  secs]  [-S]  [-t  secs]  [-T  secs]  [-v]  [-x
       conffile] [dataset]

DESCRIPTION

       opendkim-genzone  generates  a  file  suitable for use with named(8) to
       publish a set of public keys.

       The dataset parameter should specify a set of data as described in  the
       opendkim(8)  man page.  It can currently refer to flat files, Sleepycat
       databases, comma-separated lists, LDAP directories  or  SQL  databases.
       The  dataset may be omitted if a configuration file (via the -x command
       line flag) is specified referring to a configuration file that  sets  a
       KeyTable parameter, in which case that value will be used.

       The database contents should be formatted as described for the KeyTable
       parameter, described in the opendkim.conf(5) man page.

OPTIONS

       -C contact
              Uses contact as the contact information to be used when  an  SOA
              record  is  generated  (see  -S  below).   If not specified, the
              userid of the executing user and  the  local  hostname  will  be
              used;  if  the  executing user can't be determined, "hostmaster"
              will be used.

       -d domain
              Restricts output to those records for which the domain field  is
              the specified domain.

       -D     Adds  a "._domainkey" suffix to selector names in the zone file.

       -E secs
              When generating an SOA record (see -S below), use  secs  as  the
              default record expiration time.  The default is 604800.

       -N nslist
              Specifies  a  comma-separated list of nameservers, which will be
              output  in  NS  records  before  the  TXT  records.   The  first
              nameserver  in this list will also be used in the SOA record (if
              -S is also specified) as the authority hostname.

       -o file
              Sends output to the named file rather than standard output.

       -r secs
              When generating an SOA record (see -S below), use  secs  as  the
              zone refresh time.  The default is 10800.

       -R secs
              When  generating  an  SOA record (see -S below), use secs as the
              zone retry time.  The default is 1800.

       -S     Asks for an SOA record to be generated at the top of the output.
              The  content  of this output can be controlled using the -E, -r,
              -R, -T options.  The serial number will be  generated  based  on
              the current time of day.

       -t ttl Puts  a  TTL  (time-to-live) value of ttl on all records output.
              The units are in seconds.

       -T secs
              When generating an SOA record (see -S below), use  secs  as  the
              default record TTL time.  The default is 86400.

       -v     Increases  the verbosity of debugging output written to standard
              error.

       -x conffile
              Names an opendkim.conf(5) file  to  be  read  for  LDAP-specific
              parameters  when  an  LDAP dataset is given on the command line.
              Not required for other dataset types.
