We're having an hard time setting the DKIM record for our sender domain. I'll get into more details:
We have a valid key (check) for a sending subdomain (email.mydomain.com) with selector ESP1024 In the dns, the record appears to be set up properly (our registrar confirmed it) and DIG results confirms it as well.
nonetheless, whenever we send an email from that domain, the tests shows an error, finding no key for the signature: selector: ESP (instead of ESP1024) Domain:mydomain.com (instead of email.mydomain.com).
Any idea why this could be happening?
Thank you for your help
