DKIM signing via CNAME
I would like to be able to do is simply to let our clients add a CNAME record to the [domain] DKIM record (mx._domainkey.[domain], and then, when sending we could specify the signing domain for the DKIM signature.
For example: to align the domains in the example above, I would just create a CNAME record at mx.domainkey.domain2.tld which point to mx.domainkey.domain1. Then, the DKIM signature would declare the signing domain as d=domain2 instead of d=domain1
The benefits of this are:
- We don't need to continually create and manage new domains in our account.
- The domains are aligned by signing the message using the same domain as the From header.
Hi all,
Just wanted to provide an update here, this work is in progress and is scheduled to be completed in Q1 of 2024.

Any updates on this? It would streamline workflows a lot for the domain validation.
