I believe that configuring DKIM signing is pretty standard. There can be a
configuration in the default configure, but it will remain just an example,
and un-activated
because of the process required in generating the keys and the DNS records
creation.
The same can be said about DMARC. The packagers for the different platforms
could do this, but they are NOT gonna do it - because it's up to the Mail
Server Admin to do that.
DKIM+SPF+DMARC are not BASIC requirements for mail delivery. They are ways
to ensure "safe" mail delivery. I think of them as advanced methods of
ensuring the Internet is clean from spam, so they are actually addons for
mitigating spam.
It's the same way the default configuration does not include any bits to
use spamassassin/rspamd to fight counter spam - because the external
softwares require work by the MailAdmin., work which is out of the scope of
Exim itself.
