Hi,
DKIM verfication of my emails has been failing for outbound email when
received by other systems. This email contains those signatures. I don't
check DKIM inbound so that's not a concern.
I created DNS entries for both rsa and ed25519 keys.
The public TXT DNS record of dk-rsa-20240404._domainkey and
dk-metis-rsa-20240404._domainkey only contain "v=DKIM1".
$ dig +short txt dk-rsa-20240404._domainkey.rbcarleton.net
"v=DKIM1"
$ dig +short txt dk-metis-rsa-20240404._domainkey.rbcarleton.net
"v=DKIM1"
In regards to metis.rbcarleton.net no TXT records show up at all.
$ dig +short txt dk-metis-rsa-20240404._domainkey.metis.rbcarleton.net
$ dig +short txt dk-metis-ed25519-20240404._domainkey.metis.rbcarleton.net
I've also done some
reading to sanity check my DNS. Any suggestions. I'm kind of
stumped.
It has to be a problem with your DNS. The public doesn't see what you
see/think you have put in.
