SPF Records

Hello Networking Wizards -

Let’s assume there is a Web Application which is an origin for emails for multiple domains. Currently, the mail sends from WebApp to emailSenderProvider via SMTP and then sent to clients.

Now, some of the email needs to go from WebApp to emailRelay to newSenderlProvider.

Here’s where my question comes in. If the SPF records are currently setup for the current scenario, will switching up the routing of those through the new relay server and emailSenderProvider affect those records?

Your SPF record should designate newSenderlProvider as the sender.

To the outside world, that’s the server responsible for sending that domain’s messages.
