opendkim-testkey - DKIM filter installation test
opendkim-testkey [-d domain] [-s selector] [-k keypath] [-v] [-x configfile]
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.
- -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).
- 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.
The test program will also complain if a private key file is readable by anyone other than the user executing the program.
This man page covers the version of opendkim-testkey that shipped with version 2.11.0 of OpenDKIM.
