NAME

       opendkim-testkey - DKIM filter installation test

SYNOPSIS

       opendkim-testkey [-d domain] [-s selector] [-k keypath] [-v] [-x configfile]

DESCRIPTION

       opendkim-testkey verifies the setup of signing and verifying (private and public) keys for
       use with opendkim(8).

       The test program will read a domain name and selector from the command line, configuration
       file  or a key table, then query and parse the resulting DKIM key(s), reporting any errors
       found.

       If a key path is also provided, the test program will  read  the  private  key  named  and
       attempt to confirm that the private key specified by keypath (or in the key table) and the
       public DKIM key retrieved match.

OPTIONS

       -d domain
              Names the domain in which signing is to be  done.   More  specifically,  names  the
              domain  in  which  the  public key matching the provided private key will be found.
              This parameter must be provided either explicitly, or in the configuration file, or
              via a KeyTable (see opendkim.conf(5) for details).

       -k keypath
              Specifies  the  path  to  the  private key file which should be used for this test.
              This parameter is optional

       -s selector
              Names the selector within the specified domain whose public key should be retrieved
              and  tested,  comparing  it to the private key if provided.  This parameter must be
              provided either explicitly, or in the configuration file, or via  a  KeyTable  (see
              opendkim.conf(5) for details).

       -v     Increases  the  amount  of  output  (verbosity)  of  the program.  May be specified
              multiple times for increased output.

       -x conffile
              Names a configuration file to be parsed.  See the  opendkim.conf(5)  man  page  for
              details.    The   only   values  used  are  Domain,  Selector,  KeyFile,  KeyTable,
              TrustAnchorFile and ResolverConfig.  The default is /etc/opendkim.conf.

NOTES

       The test program will also complain if a private key file is readable by anyone other than
       the user executing the program.
