I have not played with sendmail.cf files in MANY years, and that was before you used m4 to configure sendmail.cf.
The FEATURE() mechanism you mention is based on using m4 as input. I would ask on a sendmail forum - I would guess that there are more people who will be able to help there.
Just know, AIX does have m4 and the sendmail.m4 files for you to experiment with.
Hope this helps - a little bit

opendkim-testkey
opendkim-testkey(8) System Manager's Manual opendkim-testkey(8)
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 UnboundConfigFile. 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.
VERSION
This man page covers the version of opendkim-testkey that shipped with version 2.6.8 of OpenDKIM.
