SPF records

[this example is “inspectionsupport.com” sends email on behalf of gfengineers.com. Add this as a txt record to the giles domain]

This allows domain owners to explain who is allowed to send email on their behalf. You can add the ISN to your SPF record for your domain by adding the following include:

include:spf.inspectionsupport.com

Thus, let’s say your SPF record is currently:

v=spf1 include:_spf.google.com ~all

After the update it would be:

v=spf1 include:_spf.google.com include:spf.inspectionsupport.com ~all

Thank you for the clarification. The Email Deliverability section in WHM relates to the hostname of the server host.digitalinfocloud.com. The respective SPF and DKIM records have been added to the DNS zone of host.digitalinfocloud.com, however these will need to be added at your registrar for the records to be properly seen by the internet due to the server having no authority over the DNS of the domain.

Any domain that would be sending from the server would have the same SPF record:
v=spf1 +mx +a +ip4:170.249.236.223 ~all

Any domains using the IP 170.249.232.173 can have this SPF record instead:
v=spf1 +mx +a +ip4:170.249.236.223 +ip4:170.249.232.173 ~all
