Custom domains and FCrDNS

[HHH]

If you set up a custom domain as detailed in https://docs.hornbill.com/esp-config/customize/customer-portal/configure-custom-domain

Will this cause FCrDNS https://en.wikipedia.org/wiki/Forward-confirmed_reverse_DNS to get a positive response for the sending email domain for mails sent from Hornbill mailboxes.

I mean will FCrDNS checks show that mails with sender address email@mydomain.com, are sent from mydomain.com rather than hornbill.com so that the checks pass.

@HH
Thanks for the post. The short Answer is "No" , there is no relationship between custom domains for the portal and sending of email.
