Confirm DKIM and SPF flow with external DNS

Howdy, We control a cPanel server with a hostname of host.server.tld. There are many cPanel accounts on that server, one of which is website.tld. The DNS for website.tld does not point to host.server.tld. An A record on the DNS of website.tld makes web traffic resolve correctly. A lead form on website.tld sends emails through host.server.tld when a user submits the form. When the email is received, the from address looks like this: ='noreply@website.com'>noreply@website.tld via host.server.tld I'm attempting to set up DKIM and SPF in order to remove the "via" portion and to improve deliverability. I'd like to know if I'm thinking about this correctly. I think that I need to add TXT records to the DNS of website.tld and that the name portion of the TXT records should look like this:

• DKIM: default._domainkey.host.server.tld.
• SPF: host.server.tld.

My thinking is that when the email hits the user's email service, the DKIM and SPF information will be attached to the email headers. The email service will then check with host.server.tld to make sure that the email is authentic. Does this flow sound correct? If so, is it correct to use the DKIM and SPF values as found in WHM > Email Deliverability? Thanks!

  Hello @John Manning, Can you provide more information about the form? Does it use the PHP Mail function, or does it make use of SMTP authentication? Thank you.

  Hi @cPanelMichael. I think it uses PHP Mail- the site runs Wordpress and uses the Gravity Forms plugin. I don't believe that SMTP has been configured.

  Install a plugin such as WP Mail SMTP
