You have correctly updated your domain to use GoDaddy SPF. That's great! You can keep hosting this email address at GoDaddy, you just have to
- Use the Postman wizard to configure the server settings
- Or manually configure Postman to use NO authentication on port 25 to localhost OR WITH authentication and SMTPS security on port 465 to relay-hosting.secureserver.net.
But very little in terms of a workflow for the items i.e. Godaddy that go wrong
That's what the Wizard is for ;-)
So do I need a Gmail MX or SPF or both set up in the DNS file?
In order to host this email at Google, you would need to pay monthly for Google Apps for Work. But your current MX and SPF configuration now is correct (for GoDaddy) and shouldn't give you any problems.
BTW, when I said
Try configuring Postman with a Gmail address using the Gmail API
I meant use something like scotto@gmail.com (or whatever) instead of dahlrestaurantgroup.com. Not to try configuring dahlrestaurantgroup.com with Gmail. That's my mistake, I should have been more clear.
