I am using Google Workspace with my custom domain email address. I am getting the following error:
spf
Action Needed: It doesn’t look like the SPF record required by Google has been added to your domain. Please check out Google’s SPF guide for details on how to add this record to your domain’s DNS.
Google’s SPF guide in Step 1: Create your TXT record for SPF, is asking for the third-party mail server’s IP address and domain names.
I have seen in several posts here that show the reluctance by WP Mail SMTP to provide SPF values to add to the DNS records. Although these emails are being sent out, there’s not guarantee that they won’t be flagges as spam.
