opendkim-atpszone(8)					      System Manager's Manual					      opendkim-atpszone(8)

NAME
opendkim-atpszone - DKIM ATPS zone file generation tool SYNOPSIS
opendkim-atpszone [-A] [-C address] [-E secs] [-h hash] [-N ns[,...]] [-o file] [-r secs] [-R secs] [-S] [-t secs] [-T secs] [-v] [dataset] DESCRIPTION
opendkim-atpszone generates a file suitable for use with named(8) to publish a set of domains authorized as third-party signers for a local domain. The dataset parameter should specify a set of data as described in the opendkim(8) man page. It can currently refer to flat files, Sleepy- cat databases, comma-separated lists, LDAP directories or SQL databases. The keys in the named database are assumed to comprise a set of domains that are to be advertised using the experimental Authorized Third-Party Signers protocol as permitted to sign mail using DKIM on behalf of the local domain. Values in the database are not used. OPTIONS
-A Adds a "._atps" suffix to records in the zone file. -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. -E secs When generating an SOA record (see -S below), use secs as the default record expiration time. The default is 604800. -h hash Specifies which SHA hash algorithm to use. Must be one of "none", "sha1" and "sha256", with "sha256" being the default if it is available. -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. VERSION
