DKIM is Verified, DomainKeys are on, but mails are sent without DKIM and DomainKeys headers

Hi,

I'm using Zoho as a my mail provider, and using Amazon - Route 53 as a DNS Server. (my domain is myclubz.club)
I followed the guidelines, and added a new TXT record to the Route 53 record set named:
zoho._domainkey.myclubz.club dor the DKIM and  zoho1._domainkey.myclubz.club for the  DomainKeys.

However,
When I send mails from my site, using the Route 53 DNS, the mails does not have the DKIM nor the DomainKeys headers.

Note that when I send the mails directly from the Zoho mailbox, they do have these headers.

Can't figure out what is wrong
Can anyone help me with this matter. 
Thanks.
