Hi, this is the error I met, please kindly help. The operation document does not work, I can barely understand it.

And how to get this below page to appear once again:

Look forward to your reply.

This seems to be a global feature in Zendesk. We have multiple email sending domains. We're about to set up our first with DKIM in its DNS records. If we flip this global switch in Zendesk, will this negatively impact the other domains' ability to have Zendesk send email on their behalf? I.e. is it either DKIM for all or none or can we set it up for select domains?

Hello @...,

I see that this question/request was already taken into a ticket with one of your admins and that they are working on it.

Have a great day and stay safe!

Does anybody know if it is possible to have custom DKIM keys? We have a large institution and do not want to globally enable DKIM for the domain. We can't use SPF.

Hey Jason,
Thanks for reaching out on the community post, I hope you are doing well!
Unfortunately not, DKIM custom keys are not supported with Zendesk's workflow.
If you have any further questions around this, please reach out to us and we'd be more than glad to help!

HI

For multibrand do we just add each brand domain as per above?

Example for two brands:

zendesk1._domainkey.firstbrand.com > Points To > zendesk1._domainkey.zendesk.com
zendesk2._domainkey.firstbrand.com > Points To > zendesk2._domainkey.zendesk.com

zendesk1._domainkey.secondbrand.com > Points To > zendesk1._domainkey.zendesk.com
zendesk2._domainkey.secondbrand.com > Points To > zendesk2._domainkey.zendesk.com

And so on for each branded domain?

Hi @...

Below is our DKIM config in our DNS settings manager:

I had to attach a screengrab as this article editor is weird. I couldn't format text correctly.

Note that Namecheap will automatically append the domain so you have to use the following for the CNAME DKIM hosts:

  • zendesk1._domainkey
  • zendesk2._domainkey

Found the solution here after wasting several hours.

 

Similarly for DMARC you have to use just _dmark as the host rather than _dmark.example.com.
